ebinmaine 63,214 #26 Posted September 24, 2018 Ahhh.... Assuming they are both good switches that would be true. You did test the one so they probably are both okay. So now it is time to back up in your circuitry to a previous position. Share this post Link to post Share on other sites
ryanmfairbank 26 #27 Posted September 24, 2018 When you turn the key to start, are we only activating the solenoid to send 12 volts to the starter motor, or is something else happening? I just trying to figure out what to check... Share this post Link to post Share on other sites
ebinmaine 63,214 #28 Posted September 24, 2018 I don't quite have enough trust in my own electric knowledge to answer that question but I will do this. You could run a continuity test on each one of those separate wires treating them as two separate issues and try to move the circuit around in your hand while you're doing it to see if there's any breaks in those individual separate wires Share this post Link to post Share on other sites
pfrederi 17,147 #29 Posted September 24, 2018 You have continuity in the switch...but do you have voltage at the B terminal all the time and also at the S when the key is in start.??? Back probe them to find out. We may have to work back towards the battery maybe you have a problem feeding the switch So you have an ammeter on the tractor??? 1 Share this post Link to post Share on other sites
ryanmfairbank 26 #30 Posted September 24, 2018 @pfrederi The ammeter was never connected and I haven’t got to doing that yet...okay, so if I back probe the “B” terminal, there should always be voltage? And only at the “S” when I turn the switch? That’s what you’re saying? Share this post Link to post Share on other sites
pfrederi 17,147 #31 Posted September 24, 2018 Yes but if the ammeter isn't hooked up the system will not work at all. All battery power goes thought it on the way to switch!!! Either install it or connect teh two wires to it to each other (bypass it) Think we finally found you r problem!! 1 Share this post Link to post Share on other sites

pfrederi 17,147 #33 Posted September 24, 2018 Do you have voltage at the B ignition terminal??? Share this post Link to post Share on other sites
ryanmfairbank 26 #34 Posted September 24, 2018 That’s what I was just asking you to clarify...if I back probe the switch at the “B” terminal, you are saying that there should be voltage without turning the switch? you’ll have to excuse my ignorance...I’m very green when it comes to the electrical aspect of small engines...

pfrederi 17,147 #37 Posted September 24, 2018 That explain a lot. OK lets work logically. Start with eh big terminal on the solenoid the one with two wires on it. Got voltage? Follow the small wire you should come to a fuse Got voltage there, then keep going probably to where the ammeter is got voltage there? Some where between the solenoid and ethe ignition switch there is a problem with the small wire.... 1 Share this post Link to post Share on other sites
ryanmfairbank 26 #38 Posted September 24, 2018 Just to clarify, the ammeter has never been connected, and I’ve run this motor on this tractor for 2 years... Share this post Link to post Share on other sites
pfrederi 17,147 #39 Posted September 24, 2018 IThey must have bypassed it some how and maybe yo didn't restore the jury rigging tehy did. Bottom line if you have voltage at teh solenoid terminal one with 2 wired then there is fault between there and the switch you will lahve to find it or run a jumper wure Share this post Link to post Share on other sites

ryanmfairbank 26 #42 Posted September 24, 2018 Okay, that’s what I’m using...and I don’t have voltage at the solenoid, so what do I check next? Share this post Link to post Share on other sites
pfrederi 17,147 #43 Posted September 24, 2018 You said you could jump the solenoid (the two big terminals and it would crank if it did yo musy have voltage at teh terminal with 2 wire...or did you jump from the batter + to teh solenoid songel heavy terminal Share this post Link to post Share on other sites

ryanmfairbank 26 #45 Posted September 24, 2018 Yes, I have voltage at the battery...I can jump from the large terminal to the small terminal on the solenoid and the motor will turn over... Share this post Link to post Share on other sites
pfrederi 17,147 #46 Posted September 24, 2018 Studied your picture ...you wired the solenoid backwards. Share this post Link to post Share on other sites
pfrederi 17,147 #47 Posted September 24, 2018 The lighter wire is on the heavy terminal that goes to the starter. it should be on the other one the one that comes from the battery!! Share this post Link to post Share on other sites
