Thanks

It is pretty consistent. A friend has a regular PowerDrive and it has no difficulty charging the batteries, regardless of their level of charge.

Thanks Steve, do you know how to confirm if there is a short? If it is the transformer, I'm guessing I'm better off replacing the entire charge - right?

90% of the time, A shorted transformer or rectifier will cause the breaker to trip before 30 seconds of charge time. I'll be you've just got a weak circuit breaker in the charger. I'd try changing that and see if it helps

. . . agree . . . I'd replace both the circuit breaker and the rectifier as they are the two cheapest parts to throw at it (about $35 total from CC dealer) . . . my friend had similar problem, so he thought he would jump out the circuit breaker . . . bad decision . . . smoked the rectifier and associated wires . . .

I picked up the circuit breaker and 2 heat sinks, but forgot the rectifier. Headed back for it now. Just looked at the circuit breaker and it seems to be larger than the original. Lists a capacity of 20A. This must be for a different charger.

Also, how would a heat sink go bad? If it was going to break, wouldn't I be able to see the problem?

Heat sinks installed, 15A breaker installed... now the charger clicks, but does not draw any amps. Fuse doesn't pop, but nothing else happens either. I'm thinking it may be a situation where the batteries are too low to charge.. that seems to be a commonly discussed topic here. I'm bringing them back up using a float charger and will try again. Has anyone else ever experienced the "single click, nothing happens" issue?

Thanks,
Matt

What's the pack voltage ? Charger only needs 30 something volts to kick on

Where did you buy the heatsinks? I'm willing to bet you ended up with two of the same heatsinks. That's your problem. People think these chargers have two 1015914 heatsinks in them but they don't. The diodes are completely inverted from one to the other. You need to order a 103517401 Double Diode board. Not "Two" 1015914 heatsinks.

Understood, but wouldn't this "fix" of two of the same heat sinks then replicate the previous issue? Now I have an entirely new and different diagnosis.
