Cat Lift Trucks (& Caterpillar) NRR40:
Line Filter Fuses Blowing

I have a Cat NRR40 that keeps blowing 15amp fuses. The fuses are on the Line Filter and there is no common time or function happening when they blow. It could be days or seconds, the fuses just blow.

I have replaced several bad coil drivers however the fuses continue to randomly blow. Any ideas? No one has been able to tell me what happens when a power conditioner fails.

I did replace several coil drivers that caused blown fuses on the PPDA board on the right side of the machine, top of the electrical mess.

"Thanks mwjago... crank and cam sensor can both be changed out at the LH rear tire under neath... Again, make sure the wiring is good... I also had a unit with a broken intake manifold so check that too."
