Thanks A833, I have done the HL relay upgrade as well. Noticeable difference! Link below for MAD amp bypass. Works great. Dunno if that's the issue I'm having right now or not. All gauges including FUEL works good, so im leaving IVR for now.
Never heard that ballast can be eliminated with stock elec ignition?? Maybe MSD etc?
Right now im trying to figure out where my voltage drop is. Everything has good ground VR, ALT, ECU.
I'm getting approx 0.8 V from ALT blue field to BATT +ve with all hooked up, key on car not running.
Approx same volts from side of ballast to batt.+ve.
These readings apparently indicate voltage drop/loss. What I've read is 0.2V MAX.
0 resistance in black wire from ALT to starter relay(unhooked).
About to double check bulkhead connectors for the umpteenth time lol.
Car is a 67 we went and picked up in Colorado in 2012.
Thanks for chiming in and kind words.
