Hi and welcome to FixYa. I am Kelly; a retired electrician.

The battery lead heating up is not necessarily an indication of a short. What it is telling you is that the battery lead is no longer capable of carrying the amperage necessary to crank the starter. The leads over time break down due to corrosion often right at the battery connector or where the chassis ground connects. Other times strand in the lead break from vibration so you have fewer strands trying to carry the same amperage as before and the end result is a hot battery lead.

Inspect the negative battery lead at the battery terminal and at the chassis terminal for signs of green or white corrosion and broken strands. If you find anything that appears like corrosion go buy your self a replacement battery lead.

If you need more assistance feel free to respond here and I will get back to you as soon as possible.

Thanks for using FixYa.

My Vy commodore battery goes flat over night RACQ jump start me they checked the alternator it's not the alternator No lights have been left on Does anyone know where the power could be draining from?


Hi Jessica, A fully charged battery is 12.6. The links below are a couple of youtube video on how to find out if a car battery has a power drain, The 1st video starts with the guy loosening the negative lead to the battery then turns the multimeter on and sets it to 20 DC, plug bottom of lead to current mode and places 1 multimeter lead on top of the terminal inside the negative lead and the other multimeter lead on the negative lead and wiggle the negative lead off the battery, The current being drawn from your battery should be less than (5.0) 50 mille volts..... The reason he takes the negative lead off after connecting the multimeter this is to save any codes from the car as technically the battery isn't disconnected.. Also, There's videos down the right side you might find helpful as well.........CHEERS..

My 1999 toyota camry changed alternator twice and my battery is still losing charge what else could cause my battery to lose charge


If your battery is the original one, it is probably getting very weak (that's 13 years old). Batteries last approximately 4 to 6 years then loose potential rapidly from that point on. If that is not the case, then you have a short somewhere in the wiring that is draining the battery.

Battery is getting drained and car refused to start after 4, 5 days.


Grab a volt meter and check to make sure your battery reads at 12.6 volts. If it reads anything less than that then then your battery is bad.
or
sounds like you have a wire grounding out somewhere. It could be any where but some of the main areas to check is the radio if it has been replaced with something other than the stock one. Also follow both negative and positive terminal leads going away from the battery, checking for loose or disconnected wires that could be touching a piece of metal. Check both positive and negative leads from the starter for the same thing as well.
Hope this helps. Best of luck.

Our 1995 GMC Suburban that isnt holding a charge


Several mechanics have looked at it, but has any automotive electricians......

what you have (sounds like) is a current drain.....what you need to do is disconnect the negative terminal from the battery and place a mutimeter in parallel,...(one lead on negative post on battery, and one lead on negative lead)...and set to current reading...it should be 0.05 amps or less...it will jump high first but will settle down.....if it is higher than this amount after a minute, something is causing a drain...

Now I have found that it could be something as a glovebox light not turning off when you close the glovebox, or interior somewhere....or it could actually be the alarm after all......

if you do find a drain, start pulling fuses to determine what might be causing it, if you pull a fuse out and the current goes from 1.2A, down to 0.05A, then you know which circuit could be at fault......

I hope this helps

New starter, alt, and battery but battery drains over night boost car and runs all day next day no start. manual transmission so i roll down hill and it starts but not when battery is totally dead


there are not a lot of computers that could be causing the drain, so baring any aftermarket accessories you should start searching for an indirect short to power

prop hood and leave the doors open... this is important because you do not want to wake the computers once you start your test

next, unplug the negative battery cable and insert a DVOM in series

drain should be less than 80mA after 30-90 minutes

if drain is higher, start pulling fuses until the drain is isolated

1990 Toyota Camry has electical short


with the aid of a test light disconnect the negative terminal to the battery and connect one end of the test light to the battery and the other end to the terminal cable if its lit there is a draw begin by pulling 1 fuse at a time until the light goes out and that's the draw most likely a glove-box switch not making full contact or a trunk switch even the dome light adjust the switch as necessary either try a shim or possibly bend the fixture forwards or remove the bulb all together if you desire
