Asked in Car Batteries What will happen if you place a wrench across a 12volt car battery positive and negative terminals without it being connected to a vehicle? It will throw sparks, melt a spot in the wrench at the point of contact and if it should stick, drain the battery and very likely ruin it. You do this just to check if there is juice in the battery and just for a second.

There are 2 terminals. The positive batttery terminal is covered by a red plastic housing. The negative terminal is not covered and is connected to the battery with a bolt that is a 10mm wrench. Take the bolt out by turning the wrench counterclockwise. Pull the terminal straight up. Its on the drivers side of the car. I believe the terminals take a 8mm wrench and then there is a support on top of it with a screw you have to remove that i believe takes a 12mm.If we can't tunnel through the Earth, how do we know what's at its center?

A dead short occurs which can result in the battery exploding A completion in the external circuit of the battery. Use a socket wrench and remove it. Disconnect the negative line first make sure it does not touch anything. Disconnect the positive again don't let it touch anythinglift the old battery out.

Install is the reverse. Asked in Car Batteries Is it right to remove the positive terminal ahead of the negative terminal? No, you should remove the negative first. That way if your wrench slips and hits a metal part of the car and the battery at the same time it will not spark. Asked in Car Batteries Do you hook up the positive or negative wire first on a battery? Always hook up the red or positive cable first, otherwise you could cause a short between the battery and the car through your wrench.

Ths of course could cause an explosion or other problems.

The black or negative cable goes straight to the engine and the car's frame, so your wrench can touch the frame when you are tightening the cable end on the battery with no worry. A loose negative battery cable can make a car hard to start. In fact it can make it impossible to start. If you don't have one you can go to a hardware or automobile supply store and purchase an adjustable wrench for a few dollars.

With that wrench, you can tighten your cable. That wrench is useful for a number of things. While you are at it, also get a piece of sand paper and clean the battery terminal.

Asked in Auto Parts and Repairs Why is it necessary to remove the ground cable first before removing the positive cable in a car? If you take a wrench and short the positive battery terminal to ground the following will happen: A large spark The Wrench will weld itself in place The wrench will turn red hot and so will your hand.By purpletexanMay 19, in Boat Talk.

I installed a new primary battery in my Sunesta which I have done many times. While tightening the nut on the positive terminal, the wrench touched the negative battery terminal, sparks flew and I dropped the wrench. No need to tell me to connect the ground first or to use wing nuts, I know I know The positive cables were on the positive battery terminal loosely, not tight and the ground cable was not connected.

Of course there were little burn like spots on the wrench where it touched the terminals but I figured no harm no foul. Now when I turn on my ignition, nothing, dead, no gauges, nada. The stereo still works so I think I must have zapped something specifically tied to the ignition, but the question is, what did I zap? I pulled the relays and the fuses on the top of the Volvo Penta 5. Is there another fuse someplace I need to look? I can't find anything, nor anything in the manual.

I also have two additional batteries for running the electronics with a Perko battery switch for "All", "1", or "2". I tried all three Perko switch settings but still nothing. Any help would be a benefit as I don't want to take it to the shop unless it's something WAY over my head. My mercruiser has a breaker on top of the engine.

If I manually trip it all engine power is off. Maybe you have one of those somewhere. Just trying to help and my response may be wrong since I know nothing about volvos. Yep, the Volvo Penta also has a little breaker box on top of the engine and I looked at those fuses and none were blown.

There were three relays one for ignition, one for engine, and something else that I couldn't tell if they were good or not since they were just black plastic little boxes, but there was a spare in there and I tried that one and still nothing. I'm wondering if there is an "inline" fuse on a cable someplace that I'm not aware of. My old Merc 5. Blew mine once doing something similar, don't know if there is one there on a VP. This may be obvious, but is the ground wire now connected?

As far as wing nuts go, they are not a good choice, as they tend to come loose. I use stainless nuts with lock washers. I also have rubber boots over each terminal, to avoid the inevitable. You'd like to think a breaker or fuse blew, not frying the ecu but I think it would still turn over.

You might check those relays too just in case. Yes brick, all cables are connected.

Like I said, the sparks startled me but I just figured no harm no foul, the battery didn't blow up in my face so that's a good thing! First thing I did was turn on the electronics and they worked fine, so didn't think much of it until I tried the key, totally dead. I agree on the wing nuts, actually had them on there prior, but the new battery came with regular nuts so I just used them. Thanks bob and betsy.

I don't know about 5, not even sure where that is exactly. Shouldn't be 20 as I pulled those fuses and none were blown.I don't quite understand the question because you didn't say if the contact was a good one or how long the wrench stayed in contact.

I'll make an attempt to answer. You would only have to to replace the battery if your action made a good contact and the wrench stayed in contact. If the contact was of very short duration, like a second then you most likely didn't do much to damage the battery.

The best answer to give you is to see if the battery still works. If you did damage it you have two consequences. You could have totally drained the battery when you shorted it. If the short lasted If the short lasted long enough the large current produced would have caused enough heat to damage the battery. Your also lucky the battery didn't explode. If the large current damaged the battery you will need a new one. The other problem can be fixed.

Then the battery can be recharged. Put the battery on a charger at a high rate for a short time then reduce the rate for a long time. Test the battery by watching the voltage while you start the car. If the car starts your OK, if the voltage comes back after the car starts.

If the voltage drops and the car doesn't start when the battery didn't take the charge. Then you will need a new battery. Do I replace the battery? Happened to me as well… Had to replace the wrench. Considering that a fallen wrench does not make a very good contact, the chances are that a diesel car draws more current when the glow plugs are energized and you start cranking.

However the wrench can be melted or damaged at the point of contact. There should have been a short spark after which the wrench falls of the battery. Its possible that your battery is ok, the chances of it being damaged are small.

Check the voltage with a multimeter, if the voltage did not drop seriously than the battery is all right. Sign In. I dropped my wrench on the battery terminal touching both terminals.

It's impossible for a spark to happen between the ground and body of a vehicle.

Touching the negative terminal will not create a spark. Are you sure it was the negative terminal? If so and the cable was connected, something is very wrong. However, if the positive cable was connected but the negative was off for safety the grounded wrench touching the negative post completed the connection and the inrush current made the sparks.

Sparks flew because the battery connection was loose until you tightened it, and you might have a short or some accessories were turned on.

Why wouldn't it be? Shorting out the battery terminals is only bad for the battery. It wouldn't cause more power to magically go to the car's electronics. Answer Save. KY-Clay Lv 7. Jason Lv 5.

I don't know what i was thinking. I wanted to make sure the connections were tight on my battery and I started to tighten the positive terminal with the little wrench included in the toolkit and as I was making sure the little bolt was tight, LOTS of sparks flew and crackling and it scared the hell out of me.

The negative terminal was connected as well at the time this happened. Also, the car was off it was not running. After I settled down I started up the car and everything seems to be ok. Thanks guys. Also, just curious Take the car to the dealer now!!!! Are you playing around with me, Albo? I know you guys have a knack for a sense of humor on here but I'll tell ya right now I am extremely gullible. Just kidding. Your car is fine. It was just scary as hell.

I honest to god thought something was going to catch fire. I'm just curious though Don't mess with the battery cables unless it's absolutely necessary. The cable is not as important as the anode. The spark happened because the wrench closed the circuit between the cathode and the anode.

Not knowing the make-up of your battery I could only guess on the cause of the spark. Maybe it was a chemical reaction on the metal surface of the wrench, maybe it was an overload of negative particles so the system couldn't hold it them longer. When you work on your car you rarely have to disconnect the battery.

For all of us Be very careful working around a car battery, as they can explode if there is enough acid vapor hovering over the battery. This is not heresay as a family member of mine had this happen to him.By purpletexanMay 19, in Boat Talk. My car battery " died " that way. It sounds like you lost your helm hot buss bar. Does the sterio run off the same buss bar or one down in the cabin?

Check for in-line fuses or fusable links. Sometimes they look like a connector in the harness, not a fuse. Check the harness and hot feeds to the helm. Start tracing each battery cable from connection to connection and test with a multimeter for continuity or high resistance. If you rule out all that, as a last resort, do you know anyone with the same boat? Try swaping out the ECM. Since your negative was not hooked up, it is probably not the ECM, but those things are touchy.

Did you fry your battery switch? Good luck. Hmmm, is your stereo wired to a house battery? That is, a battery dedicated solely to powering the stereo? Have you connected these two to the starting battery as well? Unfortunately I've exhausted the troubleshooting within my mechanical capacity so I took it to a repair shop this morning. After describing the situation, the guy at the shop said it could be a blown breaker 20 from Bob above in that the reset button didn't click when pushed so it could just be fried and he said that's no big deal.

Seems to me that the breaker's job is to trip and not fry but I'm keeping my fingers crossed it's that simple and inexpensive and will update here when I find out more. When anchored I put the switch on "2" to only draw from the two I use for the stereo. So, I have stereo power even when the switch is set to "1", thus only using the new battery that I shorted out which is I suppose my primary engine battery.

Hope that answered your question. If no ground wire was connected, then there was not a complete circuit, and you would expect only battery damage. If there was a ground connected, then a fuse, wire or electronic device fried. Cyclops2 and I mentioned, "Shorting the battery terminals creates the current thru the wrench.

Not anything else. Brick, question I just don't see how the battery is badly damaged when 1. I'm confused as all get out If the ground was not connected, than no.

A path or circuit needs 2 things, a way in and away out. In your case, only the POS was connected. As mentioned, and forgive me, it only went though the wrench. I think you must have left a wire disconnected some were OR we are missing a piece of the puzzle that you are leaving out not knowing. I had a Crownline that had a 10g wire connected to the 2 battery.
