I have had the pleasure of working in the local BMW shop for the last few months and have lately come accross an interesting problem. We're working on a custom /6 with custom wiring. There is no GEN lamp, it has been removed and i suspect that the wires are possibly shorted together, or the resistor mod was done. We will find out more on Tuesday when we look deeper into the issue but would like to prepare mentally before we tear into it. The question is this: lets asume that you remove the GEN light and short the wires together. What will happen, what symptoms should i expect? The bike is currently not charging, but it did before. We replaced the rotor a few weeks ago as the old one had no continuity. The replacement now shows no continuity, bad luck maybe . We replaced it with another good rotor, still not charging. End of the day so we went home, we'll continue it on Tuesday, starting with ruling out the regulator, diode board and brushes. Thing is without an actual GEN light, i smell a rat. Your thoughts?
