During a nice fall drive, I noticed my turn signals worked only occasionally. I first suspected the charging system although my amp meter was on charge. When I got home, I revved the engine and the headlights got brighter ( a good sign). I replaced the flasher and still had an intermittant problem with the signals. Recently, I really investigated the problem. I had just rebuilt the gen with a new arm & field coils. It was polorized and putting out a good charge. I also "motored" the generator and it was fine. The volt reg is a nos auto-lite that also tested fine. The voltage at the battery (new) is 6.30 the voltage at the flasher is 5.89. The flasher recieves it's power directly from the horn relay( as well as ignition and a few acc.) The power at the coil was 5.89. Going into the relay, I got 6.28. Going out of the relay with the relay energized I got 5.92volts. I filed& cleaned the relay points, adj the air gap and points gap and still only get 5.89. Is this a bad relay? Only orig elec part on the car! Ps: all new wiring.
