charger - puff of smoke

[go EZ]

Just got another junker cart. An old Yamaha. The old owner said he had it for 2 months and all was fine until one day the charger went up in a puff of smoke. I lifted the seat and saw 4ea 6V batteries and 2ea 12V batteries.
Does anyone know if hooking a 36V charger to to a 48V bank might have been what smoked it?

I would think that it should never have come on! I have an old Textron 36V charger that is timed charge. It will provide current when it is on whether or not batteries are connected to it. I hooked it up on my cart ( was 48V ) and it charged the batteries enough to get the cart on a trailer to bring it home! IMHO, I don't think that's what blew your charger

I just had a thought! Possibly the two 12V batts were in parallel with each other in the circuit. Then the total would be 36V. In that case the charger just succumbed to old age!

Maybe, depends on which charger it is.

If it is an automatic charger and the transformer isn't where the magic smoke escaped from, it is probably worth fixing.

They were connected in series and he said the cart was fast as heck. I told him I suppose so.
