Over Voltage
Take a volt meter and check for resistance drops at each point in the field circuit...master switch, alternator switches, alternator circuit breakers, and any wire junctions or connectors. The smallest bit of resistance can cause you to have to adjust the VR's too high. Adjust the VR's to 28.5 volts. I find the best way to adjust them is to remove them from the firewall, and mount them on a board. I have a wiring harness that connects to the wires in the engine compartment, and I can have the VR's in the cockpit with me while I make the adjustments. The adjustments are VERY sensitive
