417A no crank issue

[ALEX ANZALONE 0]

I could use some advice on my 1986 417A. I suspect I have a faulty clutch pedal safety switch as my the tractor will not crank when I turn the key. The clutch pedal indicator light goes on with no other indicator light lights on. The battery is good. Could I connect the two wires going to the switch to bypass it in order to verify the switch is bad. Also is there a replacement for this switch as it seems unavailable everywhere. Thanks, Alex.

Welcome to the forum.

Yes join the switch wires to temporarily bypass the switch.

 

110970 no longer available

Wondering if 103480 could be made to work?

As a last resort try disassembling the switch and cleaning the contacts and bending the arms if necessary to make connection.  That's what I did and it worked.  There is a plastic cap that you can remove to allow access to the contacts.  It may snap back on or in my case I had to glue it back.  Worth a try if no switch available.  The switch itself is removable by pushing it out through the side panel then disconnecting the wires.  The wires are extremely difficult to remove/reinstall from inside.

There is a blue wire connected to the black wire that is on the left side looking straight down on the switch. The wires are connected with a spade terminal on the blue wire and a thin piece of metal pushed into the black rubber boot of the black wire. I believe it was not the black rubber boot connecting this combo to the switch but it was the spade terminal. The parts list does not show this wire set up. Any idea what it is? Thanks, Alex.

There is a wiring diagram here. Click on the picture.

The 2nd wire may be for the idiot light circuit. If the idiot lights do not function they will not affect the operation of the rest of the electrical.

Unfortunately, all the idiot lights work but the tractor does not. I have headlights and taillights and all other safety switches seem to work. I will try to bypass the clutch pedal switch as mentioned before. If that does not work, could possibly be bad connectors going to clutch pedal switch which then I guess I would cut wires in areas where I could resplice them in order to bypass connectors. Also will replace main 25amp fuse just to eliminate that possibility. Hope I am not forgetting something simple. Thanks for the input.
