Thread: 36 volt battery system

You can also go to an automotive or battery store and they will load test the batteries for you.

Quit guessing, take em all out or at least unhook em, no wires connected, charge em and load test em. Just checking volts after charging don't mean crap, LOAD test em. If they are all good ohm test all wiring, if good clean all connections and put it back together. It aint rocket science, fairly simple just a pain. Good luck, hope its just a bad wire or connection.

Do a voltage check on each battery. Is this the system that you just replaced one battery in awhile back ? Its not a good idea to just replace one battery.....to do so you just bring your new battery down to the level of your older weaker ones and shorten your battery life.

Rees is right about the load test also. Measure specific gravity in each cell with a hydrometer... if it passes that then load test.

Just take em to any parts or battery store like Tommy said and load test em and replace if defective. Simple!!!!!

I am gonna check them myself, THEN take them to get them checked but haven't had time to even look at it since I found the problem. They need to be at a full charge before they can test anything any how. I went to work at 6 AM yesterday, worked til 6, drove to Florence and taught class til 9 last night. Then back to work at 6 this morning. Do you see any time on there to do anything else? LOL

One thing is it MAY be the TM. I'm going to get another Jumper and hook it from 1 to 3 and try that. It'll come on with 24 volts. Helps narrow down the problems. I just wish I'd have gone ahead and gotten a new TM when I got this one. Paid $700 for it used and I've put $500 in it one time and $300 in it another. I just couldn't afford $1300 when I got it. I got what I could afford at the time.

Had problem with my truck battery and Torch load tested it should have 800 CCA only had 500. Needless to say it got replaced. So LOAD TEST them!
