70 up charging system upgrade question

70 up charging system upgrade question

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.

I didn't know what you were referring to as far as the "MAD bypass". As far as the resistance on the ballast resistor I don't know what the acceptable range is. There has to be a plus and minus tolerance range as with anything else. Now you got me curious. If I come up with something I will pass it on. I have been informed that with the electronic ignition systems a ballast resistor is not really necessary. It was to help extend points and coil life span. It will decrease the coil life with out a resistor but it is supposed to provide more voltage at the spark plugs and there fore more power. I will be working on my ride tomorrow and will take some readings now that you got me thinking about it. I just completed converting the headlights to a relay switched configuration. Major voltage drop in the original wiring for them. I also converted my instruments voltage regulator to electronic and eliminated intermittent fuel gauge issues. Let me know if you are interested in that stuff if you havn't already done it and I will give you my info on it. What year Cuda do you have? Looks really clean from you're pics.
Cheers,
