   We can not figure out why our 3150 keeps blowing the 10amp fuse closest to the fuel tank. With this fuse out you can start and run the machine but cannot raise and lower the reels. We checked the diode by using a different one off another machine and still didn't work. Any advice would be appreciated.

   We Found the Issue! We unplugged every wiring harness one at a time to see if the fuse would still blow and it would until we got to the wire that goes into the hydraulic tank. I think this is a low level sensor. Anyway if we leave that wiring harness unplugged everything works fine.

   I agree, I recently had the same issue and it was coming from the hydraulic sensor. Anytime there is a problem follow the circuit and do a voltage drop test as it points right to the problem without unhooking a bunch of wires and getting dirty. You may need some of the small connect pins for the volt meter for back probing some of the plugs but works really well. I also find the Power-Probe works well, and if that doesn't locate my problem quickly I'll do a voltage drop test. There are some very nice videos on You Tube to show and help you under stand voltage drop testing.
