Help Solenoid or OBC

orions empire

Hi,

I am very grateful with such great community (BGW).

I have a 48V 96' 6-8v batts

My readings are 7.2v each batt, total 42 volts in the pack (actual readings, unable to charge).

My cart was running just fine, I tried resetting the OBC just to make the charger stop by it self. Everything went just fine. Charged a cpple of days, and used it and run for a week or so. The other they I tried to used it, and it only moved like an inch or 2" forward or reverse.

*** Current Issues:
Wont charge
Wont run, only an inch front or back.
Solenoid no Click

*** Testing Done:
Re-reset the OBC. (Not charging or running)
By passed OBC, Grey wire with fuse, jumped to negative at batt 6. to see if charger will work (Charger turned on for a sec and the shutdown. No run)
Replaced Solenoid (No run)
Jumpered two Solenoid Post. (runs, no charge)

HELP!!!! BTW, thanks in advanced!

OE

BGW

Sorry, I can't help with the Often Bad Component, but I will advise you to charge your batteries with an automotive 12V charger before they are ruined from sitting discharged! Take two batteries at a time ( that are connected in series ), + to + / - to - on the 12V charger. Charge each pair for a few hours then switch the pairs. I'll post a chart of what the charged voltages should be. You do not need to disconnect any of your cables to do this!
Here's the chart: I am told you can charge one 8V battery with a 12V charger! I won't recommend this, but if charging them the way I just laid out doesn't bring up your voltages enough to get your charger to engage, you may have to use the one battery charging method. I think " Shadowman " knew how to do this. I'll try and find his post for you. In the meantime, start charging in pairs! You can leave the charger on and it won't hurt a thing! :)

Thank you for your prompt response, however, my batts are 8v, if I pair them, they are 16v, can I still charge the pairs with a car charger 12v?

simple man

Yes, you are not going to obtain a full charge, though. I would do this until you see no more rise in voltage on the ones you are charging and then switch over to charging one battery at a time with the 12V charger. Here's the link to the posts I mentioned earlier:

Sounds perfect, will do right now. How do I fix the issue of no running at all, and the charging issue?

simple man

First step is your batteries! They must be properly charged to run any tests and a certain voltage is required to allow the cart charger to engage.
Also with the voltages you posted the cart will not budge!
We have a few experts on the OBC system ( which I am not ), and they can guide you on the diagnosis and repair of that system.

ohhh... LOL, well, they are charging already, one at a time, for 20-30mins at 12v@2amp. Will post in 3hrs, when cycle has been completed. Thank you for all your help. :) I am going to grab a beer, cheers...

simple man

Sounds like a winner to me!
Make sure you watch that charger!!!
Here's a sticky on how to reset the OBC, once your batteries are charged:

yes do one battery at a time and do not let it out of your sight in case anything happens, 20 minutes each one, but if your at 42 volts thats more than enough for charger to come on so if your sure charger is ok........replace OBC..........................

Everything happened when I tried to reset the **** OBC, everything was working fine. :S
