I posted a question yesterday about my factory tach not working with a stock points distributor on my 69 with an AAW breakerless conversion. I didn't get any response so I'm assuming I stumped everyone also. I did however do some reading on the site with other posts and there seems to be alot of talk about this resistor wire thats with the yellow wire that comes off the "+" side of the coil. I understand that the starter needs 12V to crank but when the engine is started the resistor wire comes into play cutting the running voltage down to 9V to avoid frying the points, which I no longer have. Am I correct so far? When my engine runs it seems to shake alot at idle, smoothing out at 1500RPMs and above, and yes the factory tach doesn't work at all. I have a blueprinted L88 427 and L88 people tell me because the cam is so big it does shake alot. I think this engine is shaking more than it should, it just doesn't seem right. I was wondering if all these problems could be from that resistor wire? If I was to eliminate the resistor wire what would be the best way to do this? I would like to avoid just cutting it until I can pinpint my problem. The only posts I've found reguarding eliminating the resistor wire are talking about MSD, Mallory and Pertronix systems, nothing about that AAW breakerless conversion. Any input would be greatly appreciated. Thanks again guys.
