I told him to get the new alternator and we'd put it on. In the mean time, I ran a fused and dedicated circuit to the headlights with a relay triggered by the ignition switch and using the factory headlight switch. No more backfeed or interference now to the gauge cluster. Thanks for the replies...

It is definitely related. I found something in the electrical manual that shows what that other circuit is for, it's for the "Exciter Circuit" for the dash and also to power the lights and accessories. I had never heard of an exciter before, but I'm guessing it uses the diode so that if voltage...

Totally agree, I told him to buy another alternator, but I wanted to diagnose it and learn, rather than throw parts at it. I think they are related, I would just like to know/learn why. I've spent about 4 hours in this electrical manual, I'd like to come away with something to show for it :)

I did. It puts out 13.9v consistently. There is also another wire that will output 7v, only when the alternator is rotating. The battery light is still on though? When I turn on the headlights, it will trip the emergency brake too. I've bypassed the main key switch, the headlight switch and the...

Ok, and for reference, here is the schematic portion of the alternator http://s4.postimg.org/lduehwspp/john_Deere240_Alternator_Schematic2.jpg

Thanks for the reply. Strangely enough, it triggered the battery light in the gauge cluster when it was switched, but the loader ran anyway and he was able to finish plowing, so we left it then but now are trying to fix it. I'm going to tell him to buy another alternator, but I would like to...

Hi, My brothers skid steer had an alternator stud break and he was able to transfer the broken wire from stud #1 (see picture link) to stud #4. I can't find anything online that specifies what both of those studs do and why they would both work? Does anyone know the difference between the two...
