Raider69 78 #1 Posted 9 hours ago (edited) Put a new brake pedal return spring on my '75 B100 Auto a couple weeks ago and when I was done the engine wouldn't crank with the ignition switch. No click, nothing, but I could turn the key to the run position, jump the solenoid and it would start right up and keep running. Switch tested good and I tried another known good one, same for the solenoid. The seat saftey switch was long gone when i got it. I replaced a sketchy looking splice in the lead to the solenoid and also put a new terminal on it. I did find that somewhere in all this the terminal for the battery negative cable had snapped off where it was fastened to the frame so I put a whole new cable on, still nothing. I had continuity across the switch but when I checked from the switch to the solenoid nada. I pulled the rectifier/ammeter mounting plate to take a look at the wiring to the switch from there. Ammeter had been bypassed years ago. I had juice from the switch to the rectifier but nothing to the feed running to the solenoid. I started to suspect the PTO safety switch...... That's when it hit me, I gave the PTO lever a pull and it moved backward, it had gotten bumped forward just enough to break the circuit..... put it all the way back, hit the key and it spun right over. Realizing I'm a moron never felt quite so good LOL. I did however take care of at least 3 future wiring problems so it wasn't a total loss. Thought I'd share that, always make sure everything is in the off position even if you "know" it is. All it took in this case was a few degrees of rotation and my total confidence it was an actual electrical issue..

Yep, and those problems probably would have popped up when I had 12 inches of snow to move in 10 degree weather and 25MPH wind gusts. I never gave the PTO a thought before today because I haven't used it in 10 years, I only use the tractor to plow snow. Now I hope the transmission problem on the Raider 12 I bought last week is something that simple. When we got it off the trailer and I was pushing it to the shed the left rear hub fell off and there was no sign of the key. The PO had rebuilt the trans and the 2nd time he plowed snow with it it quit moving. He thought he snapped the input shaft, I'm more inclined to think it is a key but I was thinking a key inside the trans not he axles. I would think it would have kept moving though as it's a 6 speed with limited slip and unless that key is sheared or missing too it should have transmitted power to that wheel. Assuming the LSD is working properly that nis. Share this post Link to post Share on other sites

Assuming the LSD is working properly that nis. The LSD is not really strong enough to overcome a missing key--“limited” being the operative word. In my experience, it is best thought of as a nice assist in “iffy” traction situations by giving some power to the low traction wheel. Worth noting is that the heavier duty JDs of the era (e.g the 318) featured dual braking or an actual differential lock. 2 Share this post Link to post Share on other sites

I wondered about that, I haven't had a functioning WH with limited slip in a long time. I vaguely recall my old Raider 9 didn't work all that great. 1 Share this post Link to post Share on other sites
