Okay, so I replaced my mechanical VR with a electronic when I did the Mad conversion and headlight relay mod. I ungrounded the one field connection to the alternator (always had a 2 field connection alternator) and bought the new style regulator from Advance Auto and mounted it with star washers and also ran new wiring to it. Not long after that I noticed a flicker in all of the lights as well as the voltage gauge. I checked.the difference in ground potential by measuring (with the engine running) from the engine block (my battery is in the trunk) to the regulator and only measured a difference of 0.1 Volts. To be safe I ran a ground wire directly from the alternator to the regulator, no change.. I checked the voltage with my Fluke meter and found it was 15.7 Volts!!!! Not Good. I did some checking online and found out that that voltage regulator that Advance Auto sells, a lot of people are having trouble with it and it appears to be due to the fact that you can't get a good ground on it through the anodized coating. I then went and ordered anot her brand new regulator from Napa Auto Parts for $35. I installed it with the same results. I then ordered and adjustable regulator online (Ebay) and was able to set the voltage to 14.2 volts and the lights are no longer flickering. By the way, it only cost me $20 with free delivery. Hope that this helps everybody else
