Power Drive Charger won't come on

[Loosewire]

Last week I installed 6 new Trojan batteries in our (new to us) '01 Club Car. On Fri., I charged the batteries and everything worked fine this weekend. Now, after using the cart a few times, I can't get the charger to even come on. All connections are clean and tight, I have 50.4 volts across the bank and have followed the instructions to reset the OBC...twice.

I checked the fuse on the gray wire and it was broken, not burned out but the glass was cracked. However, the large glass fuse on the (-) charging terminal is fine. I replaced the 3/8 amp fuse with a 2 amp just to see if the charger would even come on until I get a 3/8 amp fuse tomorrow. Still no sign of life from the charger.

Is there anything I am missing? Does it sound like my charger is bad?
