cliffyk Posted March 12, 2021 Share #392 Posted March 12, 2021 20 hours ago, Travis said: I don't think i posted this, but the other day when it acted up, i unplugged the trigger wire, and got a screwdriver and went from the BIG + on the Starter solenoid, and shorted to the trigger TAB on the starter solenoid. And of course that big + is able to provide more amperage than the trigger is. it started right up. and the way this starter system works is when the trigger gets voltage, it pulls the solenoid in and the solenoid has a piece that pushes the starter gear out to mesh with the flywheel, now of course the flywheel and starter gear aren't going to be properly aligned every time, so the starter gear is free to spin one way independent from the starter shaft. If the solenoid is getting enough power through the trigger, it should be enough force for the gear to move enough to mesh with the flywheel, i think instead the trigger isn't pulling the solenoid hard enough and when it isn't meshed just right, it can't overcome that friction. I could just start doing like Fred Flintstone.... cut the floor board out of it, LOL I am surprised the starter uses an automotive style solenoid operated pre-engagement type drive. Most modern bikes and such have constant mesh starter drives with one-way clutches somewhere between the starter and the crankshaft--the starter can turn the engine but the engine cannot turn the starter. Nonetheless, from what you describe it's obvious there is some connection/component in the starter switching circuit that is not delivering sufficient power to pull in the starter solenoid and engage the drive pinion or electrical contacts to power the motor--that's progress. Now completely disassemble the starter switching circuity wiring, clean all connections, and examine all components and wiring. If the starter itself is not the problem than it has to be a problem in either the high current feed to the starter or the control circuit. It's a "ground up" restoration of the starter wiring... 1 Quote Link to comment Share on other sites More sharing options...
Travis Posted March 12, 2021 Author Share #393 Posted March 12, 2021 I ohmed the 2 wires that come from the key switch to the relay, Both showed 00.1 ohms, Keep in mind this didn't test the key switch as the switch plugs in to the harness, so i had to in plug it and measure from the female harness end to the relay plug in end.

Travis Posted March 12, 2021 Author Share #394 Posted March 12, 2021 Same for the trigger wire from the relay plug in to the end of the wire at the starter.00.1 ohms Quote Link to comment Share on other sites More sharing options...
Travis Posted March 12, 2021 Author Share #395 Posted March 12, 2021 i also checked voltage on the 2 wires going from the key switch plug in, to the relay plug in, when i turn the key on, it shows 12.45 volts, when i turn to start it goes up to what the battery reads currently, 13.2. same for trigger. of course who knows how many amps it's getting, its probably not a whole lot of amperage, its only 18 or 20 gauge wire. so probably around 4 amps or so? One thing i can say for certain, is after replacing the big main + cable, a few weeks ago, the issue is nowhere near as persistent as it was for awhile.

Travis Posted March 12, 2021 Author Share #398 Posted March 12, 2021 okay so this is funny, Starter clicked today, so i decided to, while the was held in START, to wiggle some wires around, first i started where the ignition switch plugs in, no worky, then wiggled and pulled at the relay, no worky. i got back to the solenoid, to wiggle the trigger wire. the trigger wire was warm and the solenoid was HOT. i couldn't lay a finger on it. starter was warm, but it felt like residual engine heat. so, wonder why the starter solenoid was that hot? the whole time of wiggling wires, before i discovered it was hot was about 10 seconds. the relay was also a bit warm. i felt of the main + and - cables on the battery and they were cool. EDIT: Went out to start it again, and it hit, so i held the key down for about 15 seconds and it didn't get hot, like before. Quote Link to comment Share on other sites More sharing options...

Travis Posted March 15, 2021 Author Share #400 Posted March 15, 2021 So i guess if the ignition switch don't work i'll start on new wires for the starter circuit and connections. Quote Link to comment Share on other sites More sharing options...
kenfain Posted March 15, 2021 Share #401 Posted March 15, 2021 You should carry your multimeter on the mule. Next time it does it, test that solenoid again. While it's doing it. I still think there's a pretty good chance it's a bad solenoid. That thing getting hot seems suspicious, since everything else is pretty much new. 1 Quote Link to comment Share on other sites More sharing options...
Travis Posted March 16, 2021 Author Share #402 Posted March 16, 2021 It's done it with 3 different solenoid, but that is a good idea. Test, don't assume. Quote Link to comment Share on other sites More sharing options...

If you can establish that it's working properly, while the mule still doesn't start. You can move on to the next test. But a bad solenoid does sometimes cause these exact symptoms. And the solenoid did get hot. I'm pretty sure it isn't supposed to do that. Considering how the solenoid works internally handling a good amount of current to the starter. There's only a couple ways that it could make heat. High current draw, or some kind of short internally. I'm certain that it's not current draw, since the starter wasn't turning at that point. So it seems some kind of short is all that's left. Though I have no idea how it could be the same across several solenoids. When you install the switch, you should inspect, or even replace that trigger wire. Maybe there's crud inside the terminal. Or something like a nick in the wire. Maybe an intermittent short. 1 Quote Link to comment Share on other sites More sharing options...
cliffyk Posted March 16, 2021 Share #404 Posted March 16, 2021 I think we need to establish a taxonomy for this discussion--specifically re: the often misused term "solenoid". Classically a solenoid is an electromagnetic device in which current flowing through a coil attracts an iron armature to create motion--not specifically an electrical switching relay, though all such devices are technically solenoids. Solenoids do mechanical work often without switching contacts. Remote door and trunk locks are activated by solenoids typically with no switching function. Umfortunately in automotive terminology it has come to be the term for the high current relay that switches power to an engine's electrical starting motor--with no other function. However in the instance of the 2001 Mule which has a somewhat "old school" (for a motorcycle type engine) pre-engagement drive starter the solenoid has two functions: 1) to mechanically position the starter's pinion gear into mesh with the engine's flywheel; and 2) to close electrical contacts to supply power to the starter's armature. Here's what that puppy looks like: The big round thingy on top of the starter motor is this starter's solenoid. Battery power is permanently (I.e. not switched) supplied directly to the topmost large terminal--the bottom-most terminal is connected (through brushes) to the armature. The small 1/4" male spade connector is where power is applied to activate the solenoid so that it will push the pinion gear into engagement with the flywheel, and close the main electrical contacts connectin the top and bottom terminals to power the starter motor. Typically is this configuration there is another somewhat high capacity relay that switches power to the starter's solenoid. these other relays are also often called "starter solenoids" which can and often does lead to confusion in trouble-shooting discussions. I do not have a 2001 Mule schematic at hand, however I suspect it might included such a high capacity relay for supplying +12 V to the starter's solenoid. In our discussions we need to make sure we differentiate the two--perhaps "starter relay" and "starter solenoid". Further confusion comes about because with the contemporary constant mesh starters there is typically a remote mounted high current relay often also called (sometimes even in factory parts lists) the starter solenoid where technically it is just a high current relay. Starter mounted solenoids can of course bed replaced ad hoc, but typically they are an included component of a new stater. 1 Quote Link to comment Share on other sites More sharing options...

cliffyk Posted March 16, 2021 Share #406 Posted March 16, 2021 Cool... Pretty much as I expected it to look. That neutral switch could be a culprit too--a simple test would be to jump or connect that light green wire at the neutral switch to ground. That will bypass the switch ruling it out as a bad guy (or proving it to be the bad guy)... 1 Quote Link to comment Share on other sites More sharing options...
Travis Posted March 16, 2021 Author Share #407 Posted March 16, 2021 I actually replaced it last year due to it went bad, as it totally cuts power to the solenoid at the relay. But i will try that. Quote Link to comment Share on other sites More sharing options...
Dan B Posted March 16, 2021 Share #408 Posted March 16, 2021 It's extremely common for solenoids to switch electrical contacts through magnetic forces. We call them relays and contactors. A solenoid can't do any work unless the iron core is connected in some way (mechanically or through magnetic attaction) to a device. Just about every electrical appliance in your home, your car, your water heater, your AC unit has a relay or two. Without solenoids closing relay contacts, that switch would have to be designed with extremely heavy contacts and run ALL of the battery power directly to the starter (which is technically a motor, not a starter). It boils down to a matter of semantics and generally accepted terms for laymen. Engineers view these much differently. Quote Link to comment Share on other sites More sharing options...
cliffyk Posted March 16, 2021 Share #409 Posted March 16, 2021 That's pretty much what I thought I said.. My specific point was that we (and I am as guilty as anyone) have been using the term "solenoid" to refer to both the electro-mechanical device on the starter motor that both causes the starter motor drive pinion to engage AND closes the heavy duty contacts (typically a copper disk and the terminal bolts heads) to switch power to the motor.

cliffyk Posted March 17, 2021 Share #419 Posted March 17, 2021 Joe, I likely overreacted--it is a topic I am a bit peevish about--on Labor Day of 2019 the family had a celebration of my accomplishment when my drunken 27-year-old step-grandson¹ stood in the centre of it all, and declared for all to hear; that he "didn't think it was that big a deal" His mother ad father very nearly died right there on the spot. My wife says I bring it up too often--she's probably right (why are they so damned right so often?)--but for me it represents the likely "end posts" of nearly 50 years of work and aspiration--it is an accomplishment I am quite, and no doubt overly; proud of... ---------------------------------------------------------------------------- ¹ - Whose life accomplishment after dropping out of UCF is being a part-time barmaid at Starbucks in Orlando.
