Everyone is going to want some more info.

You have a 36v GC charger right?

What type of 12v batteries?

If you are running 6 12volts you are running 72 volts.
Thus blowing up everything on your controller.
If you are running 12v, then you only need 3 batteries.

i do not have 72 volts. i have 36. two banks of 3-12 volt batteries in series, giving me 36 volts, then those banks are in parallel, giving me twice the amperage. i have a resistor cart anyway so there is no controller blowing.

yes, it is a standard 36 volt timer GC charger.

i have 12v gel cell batteries by datasafe. they are now golf cart batteries but they work. my only problem is charging them.

If you have them wired for 36v and charger is 36v wire as if they were 6 6v. One lead from charger receptable to first battery, other lead to last battery in pack. It will take longer charging times.

Can you draw us a diagram of how you have these wired. I am curious. There could be some problem with drawing from one bank more than the other and the same with the charging circut.....

if i wire the 6-12 volt batteries as if they were 6-6 volt batteries then i'd be charging 72 volts. the way i have them is in fact 36 volts. my charger was working fine but when i went to charge it the other day, i turned the timer knob and it started but then shut off and not even the timer worked. not to mention it smelled really bad. i took the cover off and as far as i can tell, it's ok but it wont work. that is why i am questioning it.

OK, now we get the root of your problem. Saves time if you "tell all" in the first post. ;-)

Is the charger in question a Total Charge? More info on the charger and maybe someone can help you troubleshoot your charger.

Are you running 12v backup batteries?
