I need some help /o/ I did some research but ill ask you fags

Yep. Battery is done.

Wire brush and water mix with baking soda to neutralize any acid. Check the voltage, if less than 12.5 volts try to put it on charge and try to start it again.

can i use this to check it or will it explode in my hands

>>14693889
put it on DCV 20, it should read around 12v for a charged battery...if it's charged, just cleaning and tightening the battery terminal could fix it....how old is the battery

If its old, adding distilled water to the cells might help.

Clean your cables properly and remove them from the battery. That corrosion was once your terminal(s)

car battery voltage is usually around 13.4V fully charged
12.5V is 85%

I have the same question, my car won't start.
I turn the key and It just goes one click.
I have replaced the battery with a new one but that didn't seem to be the problem.
I was thinking it might be the starter, but I don't know what to actually do with it. I have heard they are extremely reliable pieces and you only switch it about once in a cars lifetime.
I also tried jumping the car, but it only just went 1 click. Are there any other possibilites than the starter making trouble,and what measures should I take if it is the starter?

Grab a huge gallon or so jug of warm water and pour it on the battery until all the corrosion dissovles

baking soda and water is best for cleaning battery terminal corrosion with a small wire brush. Fully charged battery is 12.6V volts, I wonder what your voltage drop from your terminal to ring is.

Grad a piece of wood or something to reach the starter and try hitting the starter (not too hard) while someone turns the key. If it turns on, you know the problem is with the starter.

This helped me many times in my Jeep before I got around to replacing the starter motor.

12.6 is fully charged..there are 6 cells of 2.1 volts each

This. OP should just recharge the battery and have it load tested

Same happened to my car. Needed a new battery and cleaned up the terminals (mechanic did the latter so idk how to personally do it)

Water and baking soda mane. Hell, you can even use a can of coke

no, it's way higher. do i have to grab my repair manual?

>>14694266
I'll check it out, but not sure what can I do about it. Does it need to be replaced or just cleaned with a metal brush?
>>14694310
Which part do I try to hit and how gentle/hard should I be? Like a harder tap or something or like a decent hit a metal would have taken?

The car in question is 26 year old Corolla.

Tap the solenoid, on the casing near where the positive terminal connects to it, probably.

Hit it about as hard as you would knock on a solid door. A few solid taps, nothing too hard.

The idea is that if your solenoid is sticky, some tapping can help dislodge it and get the car started. Not a permanent fix, obviously.

If you're alone you can try to tap first then try to turn it on, but I doing it at the same time seems to work better.

>>14694744
Thank you for your input, I can't wait to test it out tommorow.
As for a permanent solution, I guess I should switch the whole starter out?

>>14694766
Make sure you get a new solenoid too.

>>14694766
>I guess I should switch the whole starter out?
You could probably get away with the just solenoid, but the whole starter and solenoid set would be best, since its an old car the motor is probably worn. It shouldn't be that expensive.

Please... Please try harder with the faux content.

i like using a electric toothbrush over a wire brush.

>>14694101
that's a surface charge, gives false positives. Now what the OP needs is a carbon pile tester to check for dead cells.

In my country we use a lemon , it does the job

Didn't mean to post twice, but you can go fuck yourself :^)

12.6

>>14694537
It shoulsn't be higher 12.6 is fully charged. Unless your shit is about to blow up.
