ok here it goes.
My cb starts and runs for about 20 to 30 minutes. Then the headlight starts dimming and it dies. I charged the battery and stated it. Im getting less than 13v at the battery when its running. I checked the ohms of the stator and field coil and they seem ok. Then load tested the battery. Again ok. How do I check a voltage regulator? This bike was the victim of an electrical fire. I rewired it and its correct. Any help at all would be appreciated.

check your fuel tap. it could be blocked. might be enough fuel drain through for it to go for that long then stop. Hope this helps.

Fuel wont make the lights dim.
its a mechanical regulator, should be able to take it apart and check contacts. If bike has been in a fire them could easily be stuck.
probably best thing to do is start saving for a solid state reg/rect.
