Re: IH 674 Bypassing alternator safty switch

Wire diagrams found, I think I burnt the resistor/diode, I just want to bypass it, Alternator shop told me to run the small wire to key switch, I guess I can try and find the diode/resistor and just bypass it.

Should I place a 12 volt bulb going to ignition that's what alternator shop recommended, It will act like a fuse as well? is it safe to strait pipe it?

Bypassed the red light integrator for charging and its now works . :dance1: Don't really need it because I have a volt meter in the dash. Plus can't find one online
