Hello Guru's of the Green!
I have scanned and tried suggestions from a couple forums for my issue. I have the tech manual and have tried as best I know to diagnose the electrical nightmare I've stuck in. Any help or suggestions will be attempted and reported on. Thank you in advance.
Here we go:
Background: I purchased 2005 2305 in Oct of 2014 with a possible issue of blown head gasket. Turned into a cracked head with #1 & #2 having cracks between the injection and intake ports. I enjoy getting grease under my nails and did get that fixed up $1200 in parts later.
It had run great up until about 3 months ago (been struggling with diagnosing) when I had tried to move it for some errands in the yard. I had warmed it up for about 10 minutes before moving it about 30 feet and it quit. I turned the key off and turned it back on without trying to start. Noticed the fuel gauge did not move. I check under the hood quick and found the 15A fuse blown. I checked all others under and they were good. At this point I came to the forums. Checked the V4 diode, as well as all others, and found a couple that were bad and replaced them. Put another fuse in, turned the key on for the glow plugs, the fuel gauge moved, and I cranked it up. It started and ran for about 15 minutes. I then went to move it again and it blew the fuse again. I hit the forums again and tried to diagnose the K3 & K5 relays (replaced both), I changed the fuel filter (did have some water in the bottom) and fuse. Turned the key on, gauge moved, plugs warmed up, and it started up again. Warmed up about 10 minutes again and tried to move and it died again after about 30 feet. I was wondering if it was related to extra stress from turning the steering wheel or raise the 3pt hitch. There were a couple attempts between the 1st and this last attempt that seemed to point that direction. This last attempt includes replacing the fuel shutoff solenoid, fuel shutoff timer and fuel shutoff relay. I have rechecked all the diodes (7). The seat switch is by-passed for testing. The PTO is off, not used since I've owned it. The replaced parts include many 15A fuses, K3, K5, A1, K2 & Y2. The only part I have not tested (or found yet) is the neutral safety switch.
I have tried to follow everything in the schematics that touch the F2 fuse. Not sure where else to turn, unless I got a bad safety relay from the shop (K3 or K5). Will try to find the neutral safety and test, but would like some more thoughts, if there is something I may have missed.
Thank you again for any assistance.
