So I recently bought an 85 535i and I have been experiencing charging issues. Has anyone else had similar problems? I have replaced the idiot light bulb in the cluster but its still not coming on. wondering if i have the alternator ground strap in the wrong location and its possible that it is causing my issue. ( I replaced the alternator recently. ) tried even finding the circuit for the idiot bulb and bypassed the cluster but still no luck. Found power on both sides of the bulb in Key on, Engine off when I am suppose to have ground on the blue wire. I should only have power on both side of the bulb in ignition position KOER. Any thoughts?
