Crown FC-4000:
FU1 fuse blowing

Hello all, I have a Crown FC-4020- 50 and it keeps blowing the FU1 fuse, sometimes the fuse will last a month and sometimes the fuse will last a few hours. I am hoping someone can point me in the right direction, I have not even started to diagnose the truck, so I am hoping to have a little bit of direction before I start spending a bunch of time on it.
As always thanks in advance, you all are a great help.

I don't think that is the case but I will check it. I was thinking more along the lines of contactors getting stuck and causing a direct short.

Check the condition of the battery. High amps in the drive circuit. Maybe the operator is pushing pallets? 36v truck Shouldn't drop below 30v under load.
