Have been working on a 1975 Century Arabian with a Chrysler m440. Dropped the engine back in the boat after redoing the stringers and am working on reconnecting everything. Plugged in the wire harness and went under the dash for a while to test gauges and such with the key in the on position. After about 10 minutes went back to the harness to trace a wire and he ballast/resistor was really hot and the coil was warm. Voltage on the gauge reads 11 volts and if I remove the ignition wire it jumps up to 12.5.
Understanding the purpose of the ballast is to resist current to the coil - but should the voltage read that low while the key is in the "on" position. Thanks.
