head lights pulse after bypassing my bulkhead

................... Then I ran a jumper from the battery positive to the 12 volt input to the regulator and everything was just fine--nice steady 14 volts. I found a 0.5V drop between the battery voltage and the voltage at the regulator input wire. All the wiggling of the bulkhead connector wouldn't clear it up so I put a relay in and all is well. .

VERY GOOD!!!!


No, bad diodes won't cause this. I actually PURPOSELY ran with only 3 diodes "back in the day"

My alternator had quit, I tore it apart and don't remember, I think one phase was screwed up. I vaguely remember I had one that vibrated the insulation off, LOL

So I was broke "till the end of the month" and ran without one phase of the alternator. You could NOT LOL listen to the radio!!!!! There was little else (at the time) that was electronic. This was in the 69RR, around 1970
