Now for the fun part of tracing all of this down with the wiring diagram. Smitty The PLUG will work. The WIRES.... well have fun. That plug uses a Delco/Delphi (?) Wire end. Here's a pic of my own. 3 Share this post Link to post Share on other sites

smitty316 24 #30 Posted August 5 I'm making a little progress on the wiring situation. I wanted to make sure that my pencil is pointing at the LOW OIL RELAY in image 2224 before I go any farther. I have a new ignition switch ordered so I'm trying to get it cleaned up first. They cut and spliced several wires to make the other switch (kind of) work. My goal is to get the critical wires correct so it'll run and then go back and replace and rewire the safety switches. These have all been cut out of the system.

Bill D 1,916 #31 Posted August 5 (edited) How comfortable are you with wiring? I built my own replacement wiring harness from scratch with mostly new wires. I kept the wires that go to the clutch switch as I didn't have a good source for those 90° terminals. I based my wiring on a 1982 C165. Very simple wiring with just the basic safety switch, seat, clutch and PTO. Since my tractor has a Magnum engine I used a 5 pin relay to kill the engine.

smitty316 24 #32 Posted August 5 Thanks Bill, I'm comfortable enough to get myself into trouble. I think I'll stick to the wiring diagram and keep it as original as possible. I wanted to make sure that the pencil in my picture is pointing at the Low Oil Relay. Thanks, Smitty Share this post Link to post Share on other sites

smitty316 24 #34 Posted August 5 Anyone know where this Pedal Interlock Switch is located? Thanks, Smitty Share this post Link to post Share on other sites
smitty316 24 #35 Posted August 5 Also, A second opinion would be greatly appreciated. It looks to me like the wire from the LOW OIL SWITCH goes into the LOW OIL RELAY, and then into the PEDAL INTERLOCK SWITCH and then through the PTO INTERLOCK SWITCH and then into the START TERMINAL of the IGNITION. If this looks like it's the case, I'll just run a temporary wire from the LOW OIL RELAY down to the START on the IGNITION. I just don't want to burn anything out.

Handy Don 12,204 #36 Posted August 5 Any of (or any combination of): - the PTO switch (PTO engaged--the tan/purple connection), or - the pedal interlock (pedal not depressed) or - the low oil relay (not enough oil in the engine) will prevent the starter solenoid from energizing. Any bypass of these adds risk to both the operator and the engine. 2 Share this post Link to post Share on other sites
smitty316 24 #37 Posted August 5 I totally get that and this is why I plan to replace all the safety switches at some point. It's just that the previous owner cut them out of the system and rearranged wires to make them work on the wrong ignition. I have a new, correct ignition switch coming so I'm trying to get all the main wires connected first just to get it running. Then I'll go back and do the switches one at a time.

953 nut 55,163 #40 Posted August 5 5 hours ago, smitty316 said: make sure that my pencil is pointing at the LOW OIL RELAY Yes it is. The low oil switch will be OPEN if the Oil Level is good and the relay will NOT be activated. If oil level is low the switch will close activating the relay and preventing the solenoid from closing. 1 hour ago, smitty316 said: Anyone know where this Pedal Interlock Switch is located? Thanks, Smitty I believe the clutch switch is located in the tunnel between the operator's legs on the right side. You can seer the switch from the outside by removing the belt guard. The rod that goes back to the clutch arm has a tab on it that activates the switch. 1 Share this post Link to post Share on other sites

I just acquired an Allis Chalmers B-110 which was built between 1968 and 1972. While coaxing it back to life, it playfully reminded me that it had no safety switches by starting to climb onto my foot with the front wheel while I was jumping the starter. Forgot to put in neutral before I started to work on it. Think I'm going to add a starter relay with a safety switch on the clutch so it needs to be depressed before engaging the starter. 3 Share this post Link to post Share on other sites

If your intention is to just get the engine running you can remove the wire that connects the low oil switch to the relay and the relay will not prevent the starter from turning over. 21 hours ago, smitty316 said: I didn't really follow you on that 953 nut.

A member posted a video a couple years back of getting a round hood soil plow tractor stuck. He hopped off to free it and then restarted the tractor standing next to it. It started fine but it was in gear and he was not on solid footing. Narrowly avoided getting run over by both the tractor and the plow. I realized later that the videographer was not paying attention either--focused on the shot and not the situation. 1 Share this post Link to post Share on other sites
smitty316 24 #45 Posted August 7 The next thing I need to do is clean out the fuel tank. Does that valve just pull out of the tank? Or how do you get it out so I can flush the tank out. It's full of rust and crud. Thanks, Smitty Share this post Link to post Share on other sites
smitty316 24 #46 Posted August 8 I just watched a YouTube on how to use a weed eater line to get it out. Should I automatically plan to replace it if I remove it or can I put it back in without it leaking? Thanks, Smitty Share this post Link to post Share on other sites
