Re: GC2410 Neutral Switch? Engine Died
PARTIALLY SOLVED! With the schematic in hand, I found the single accessory circuit - traced from the ignition switch - that powered all the potential problem sources: fuel pump, safety and seat switches and the dash. I checked the 10A fuse for that circuit and sure enough, it was blown. Replaced it and it blew as soon as I turned the key. Went to get more fuses and decided before toasting any more fuses to check the harnesses going to the safety and seat switches - mostly because this occurred soon after I had been using the backhoe, necessitating the moving of the seat back and front. First harness I checked - the seat harness - was cut in two. BINGO!
I unplugged the harness to isolate the short and put in a fresh fuse, and the dash and fuel pump came to life. YAY! Of course, it wont start that way, so I repaired the harness for the seat switch, tested the switch for continuity, and reinstalled. Sadly, it got me no further. Dash lights up, fuel pump clicks, but no start. Drat!
I'm following the circuits for the other two safety switches to see if they have continuity. The PTO switch was turned on its mount so it was not able to be engaged when the PTO clutch was engaged, so I straightened that out. I will be checking it for continuity, but the tractor was running with it that way, so... The neutral switch harness disappears under the seat assembly into a jungle of linkages, and I haven't found the connect point yet. I will next remove the seat assembly in the hopes that uncovers the harness. If not, it looks like the fender assembly would be next. Hopefully I won't have to go there.
Still miles to go, but the schematic was the key to getting this far.
