I think we **may** be on to something here. I am not going to get my hopes up though....

So with the ley in "run" I have ~11.7V on the blue side of the ballast resistor and ~4V on the brown side. This is quite a drop. I measured resistance across the resistor and it shows ~2 ohms which should be OK....

I am guessing this means there must be a huge draw on this circuit somewhere that is causing such a drop on 2 ohms! This is with choke disconnected. The only other two things I have are the ignition wire for the fan relays, the ECU, and the blu field on the alternator. Must be one of the three shorting to ground or the wires themselves....

Also, I have ~1V on the "-" terminal of the coil in "run". Is this normal or supposed to be grounded (near 0 V)?
