Lane Huls 146 #1 Posted May 29, 2016 Ran onto my trailer, get home and I won't start. Has fuel, only sparks after I let off the key? Share this post Link to post Share on other sites

953 nut 51,720 #3 Posted May 29, 2016 Presuming the electrical system on your 877 has not been altered you should have 12 volts going to the + terminal of the ignition coil when you are in the start position and the run position. Check it out and see what you have. here is a manual with wiring diagram for you. Share this post Link to post Share on other sites
Lane Huls 146 #4 Posted May 29, 2016 Tester is currently in my broken down car not with me. It was started several times in front of me. The wiring has all been replaced. So altered is my retry much a yes. Turning over I have no spark. But the second I let off I have spark til it stops turning. Share this post Link to post Share on other sites
squonk 38,936 #5 Posted May 30, 2016 I'm thinking the contact of your switch in the start posistion is shot. Being a starter/gen model, if there is no starter solenoid on the tractor to handle the load that contact would take lots of abuse. Share this post Link to post Share on other sites
Lane Huls 146 #6 Posted May 30, 2016 Just tested a confirmed good switch. Same deal. The switch in it looks brand new. Only have 3 wires though. S L B, all connected well. Share this post Link to post Share on other sites
Lane Ranger 10,495 #7 Posted May 30, 2016 I had to clean the gunk, paint and corrosion off the A terminal on the Starter/Generator of my 701 today to get a complete hot wire connection to start the tractor. I was surprised but pleased to find the solution! A check light should help. 2 Share this post Link to post Share on other sites
Lane Huls 146 #8 Posted May 30, 2016 One of those terminals was loose, but I tightened it up. I'll clean up some. 2 Share this post Link to post Share on other sites
Lane Huls 146 #9 Posted June 2, 2016 To revisit this, I ran the coil wire from the switch straight to the battery and I have spark like I should! The real question now is I tried 2 confirmed good switches. 1 new even, along with the old one. None of them are getting 12v to the coil while cranking. What gives?
