BMW R80/7, help needed doing re-wiring
Posted: Mon Mar 17, 2025 1:55 pm
Update: So figured it out. In original wiring there is "starter relay" that could be deleted when installing M-unit, as starter has it's own solenoid which is driven by the Mo-unit "Start" x2, IGN -> Coils and load to OEM alternator light could be just taken anywhere basically.
Could you help me to fill up my own wiring diagram what it comes to wiring starter relay, as I think I cannot get it done without it? As far as I understand, pin 85 goes to M-unit IGN and 30 goes to coil as in original Boyer setup. How about rest? I know that I have to have that charger filament light or 330ohm resistor to get charging working right.
