ERC040AFN is a 4 wheel sitdown 36v counterbalance.
i presume the fuse it is blowing is the control fuse in the fuse panel? then start back probing till you find the short, it's either wiring chaffed and grounding or a bad component or something along those lines.

I highly doubt it's a battery cable, if it is that, you will definitely see sparks and fire and smoke so finding one of those cables shorted should not be too hard. ;o)
