'76 pulsing headlights & swinging ammeter - pic
I have a 76 FJ40 that I have replaced the alternator & battery &
voltage regulator. (I first tried a new rebuilt Toyota VR and then a
Transpo solid state unit - alternator is new Toyota OEM rebuild, battery is new Optima)
My headlights pulse, brighter & dimmer and my ammeter swings wildly at idle and less so at speed but the ammeter is never steady. Any ideas on how I might smooth out the electrical system to get stable lights and calm down the ammeter?
My only idea is that maybe the wires into the alternator are not set up right. (see pic of old alternator but wire set-up is the same on new one)
