new to horses 1 #1 Posted October 28, 2023 I need assistance in knowing if this solenoid is hooked up right??? Also when I try to start it as shown the red wires with the fuse get hot, not crazy hot, I can still touch them. Is that normal? Share this post Link to post Share on other sites
Rick3478 377 #2 Posted October 28, 2023 Looks right. The little red wire carries all the current to everything but the starter, and also the charging current. I wouldn't expect it to get hot, though. Maybe something else wrong, like shorted rectifier/regulator, safety interlock, or even hour meter? Share this post Link to post Share on other sites

I should add it blew a 20 amp fuse… it should have a 25 amp fuse I know but I didn’t have one so I replaced it with a 30… Edited October 28, 2023 by new to horses Share this post Link to post Share on other sites
953 nut 51,970 #5 Posted October 29, 2023 The electric demand without lights on should be minimal. Your charging currant should be less than twenty amps and your ignition (if it has a Magnum engine) is self powered. Check all of your wires tom seem if something isn't pinched or abraded where it will make contact with ground. Share this post Link to post Share on other sites

Not to sound like an idiot but I’m at my limit with electrical… I’m terrible with it and have limited knowledge on what to do next. Share this post Link to post Share on other sites

Need to figure out where all that current is going. I'd arm myself with a wiring diagram and a meter with a high current range. In the absence of meter, a 12V incandescent light bulb can serve as a current indicator. Substitute light bulb for the fuse and observe brightness. Start unplugging things, and if the bulb dims or goes out you know a bunch of current was going there. My money's on the rectifier/regulator, but you could have worn through the seat switch wire somewhere, and there are other possibilities. Found diagram elsewhere on the forum. 1 Share this post Link to post Share on other sites

oliver2-44 8,880 #10 Posted October 30, 2023 Those bypasses may be a good area to look for poor wiring work by the previous owner 2 Share this post Link to post Share on other sites
