96 CC 48v Charging issues??

[tmck]

I have a 96cc 48v. I have had the batteries checked and replaced 3 of them. The charger worked fine the first 2 or 3 times I charged it. Now, the charger just clicks and humms with no charge indicated on amp meter. Every so often it will decide to charge and when i come back to check it the little fuse on the bottom right side of charger is tripped. Any Ideas????

powerdrive charger? heatsink and diodes....and replace the breaker.......................

How long does it charge before it trips? A bad heatsink will usually trip it within 5-6 seconds

It is a powerdrive charger. I have watched it for 10-15 minutes and it never trips while i'm watching. I don't think its a charger issue. I think the problem is in the cart. I have hooked the charger up to other carts and it works fine.

check all your batteries, load test them...even if you think they are good test and load test them , than clean everything every post ,cable end, and plug on charger where it plugs in and same with cart receptical............get those 2 as best you can.....also go over wiring and do resistance test on battery cables......could be a cable going bad under the insulation that you can,t see............................

I'll load test the batteries, check the cables and let ya'll know how it turns out.

I just left the golf course and thought i would plug in the cart to see if it would charge and what do you know, it came on and is charging fine. I am going to go back and check it later( to see if it is still charging and to see if fuse on charger is tripped) . Any ideas why it sometimes charges and other times it doesn't?

It doesn't sound like a heatsink problem at this point... It's probably just a bad circuit breaker in the charger. Sometimes the spring inside them gets weak and will randomly trip for no reason.
