My 70 Dart is having the same problem, high voltmeter readings and flickering lights, while engine is running. But when I hook a jumper wire from the battery to the DKBL regulator/ ignition terminal then it works fine. So i will install the relay as outlined. Now normally the ignition switch feeds 12 V to the center terminal of the regulator, as well as the blue field wire going to the alternator, correct? So with this fix, the ignition switch now activates the relay. Then the relay sends voltage directly from the battery to the regulator as well as the blue field wire on the alternator. Is that right? Thanks, mine has been a source of distress too.
