partsman86 3 #1 Posted April 21, 2020 (edited) ammeter went bad burnt wiring. I replaced entire harness with a new genuine wheelhouse harness. lucky to find one. tractor won't turn over it does if I jump solenoid but won't start. it acts like when the mower blades are engaged and it keeps it from starting. is there a way to jump that switch? witch terminals do I jump? when turning over by jumping solenoid there is no power at the coil should there be? help thanks. I've also tried a new solenoid and ignition switch Edited April 21, 2020 by partsman86 Share this post Link to post Share on other sites
briankd 819 #2 Posted April 21, 2020 (edited) could be one of the safety switches my c 120 had one on clutch one on the pto lever i got rid of my switches just 2 wires put them together check the points had one would crank but not start and the points was burnt and the condenser shorted out .my ignition switch went bad and burnt the wiring up. make sure you have the correct ign. switch there is a battery or magneto one they won't interchange i found out the wrong way Edited April 21, 2020 by briankd 1 Share this post Link to post Share on other sites
Achto 29,253 #3 Posted April 21, 2020 First make sure that you are getting battery "+" power to the "B" terminal on the switch. Turn the switch on, you should have power at the "I" and "A" terminals on the switch. The "I" terminal will feed power to the + side of the coil as soon as you turn the switch on. Turn the switch to the start position, you should now have power at the "S" terminal on the switch. The "S" terminal will feed power to one of the small wires on the starter solenoid. Power from the "I" and "S" terminals can be interrupted from their destination by safety switches. 1 Share this post Link to post Share on other sites
partsman86 3 #4 Posted April 21, 2020 Is there away to jump over these safety switches? The pto switch has a 4 or 5 pin plug how do you bypass that? Share this post Link to post Share on other sites

Look through the manuals for a manual with a wire diagram for your tractor, this will help you out a lot. Is the 4 or 5 pin plug connected to a relay? If so you need to figure out which wires close the coil on the relay & which wires are the switched wires. You will need to tie the switched wires together to complete the circuit/by pass the switch. . 1 Share this post Link to post Share on other sites
