trwebb26 Posted October 5, 2006 Share Posted October 5, 2006 I've been fighting my car for a couple of months now. My latest problem is that my car won't run if the alternator wire is hooked up. I'm running the GM 1 wire alternator and if you disconnect the wire - it runs fine. With the alternator hooked up - the car can idle - but won't rev up due to dropped timing events. A little more about my setup: 78' 280z megasquirt v3.0 running ms&se 280zx turbo dizzy gm 1 wire alternator msd 6a running to msd blaster 2 coil to taylor "spiro-pro" wires The investigation I've done so far has been with an oscilliscope. It seems the signal from the megasquirt to the MSD box is good - but if the alternator wire is hooked up - the signal leaving the msd box is junk. To remedy the problem - I tried installing MSD p/n 8830 - an inline capacitor that is supposed to shield any RF noise from the MSD unit. It didn't do anything. Please help me troubleshoot this thing. I'm desperate. Quote Link to comment Share on other sites More sharing options...
