A friend has a 1993 Case 2wd 1100 series tractor w/ a mounted Woods 165 front end loader which can’t be dismounted. I was told the husband disconnected the OSHA required safety equipment. 9 years ago, he was mowing with a brush hog and the tractor died. It would not restart. It was towed to the shed and sat. He passed away not long after this. Several mechanics, (?), have looked at it. The wife was told it needed a new wiring harness, I looked at it but didn’t have a test light or multimeter. I turned the engine over with a wrench on the crankshaft nut. I installed what I was told was a new battery. I checked the cables, Positive goes to top post on starter and negative goes to frame under the battery, Terminals look good and no rust on negative cable mount to frame. None of the gauges, light that flows on preheat or the lights work. The starter does not engage. I checked for a battery disconnect switch and found nothing. Not knowing the condition of the battery, I hooked up my jump pack. No difference. I found a remote starter switch and hooked it from the top terminal of the starter to the small male spade terminal on the solenoid behind the starter. Starter didn’t engage. Not knowing if the remote starter switch was good, I tried a screwdriver, starter didn’t engage, no spark or noise. I found the fuse box, it has 4 fuses, top to bottom, 20 amp, 10 amp, 10 amp, 20 amp. but the bottom 20 amp fuse was missing. The other 3 fuses are good. I took the top 20 amp fuse and put it in the bottom 20 amp holder, no difference in gauges, lights or starter. My jump pack was still fully charged when I got home. Any ideas where to start? I was dumbfounded when I jumped the starter, and it didn’t crank.
