Has anybody heard of the MAD electrical upgrade to bypass factory ammeter. (www.madelectrical.com) . They have numerous articles but this one caught my eye. Basically running juice from alternator directly to starter relay instead of through firewall connector and all up through the dash. You fuse the thick red and black wires where factory ammeter used to sit. You still need this loop to feed ignition switch, etc. This loop is also attached to starter relay. They also by pass the fragile firewall connector for these two wires. Supposed to reduce risk of melt down greatly. And of course then you need to install an aftermarket voltmeter in place of the now absent factory ammeter..MAD isn't just Mopar but this upgrade is specifically for Mopar. They do it on a 79 Dodge truck but it should work on the older stuff too.neal
