Since you are installing an alternator that has internal voltage regulation, you MUST remove the OEM Reg/Rect unit.... if you don't you can cause a fire in the wiring because it will attempt to shunt the new alternator straight to groundSince I cooked a brand new stator last summer, (Got a whole whopping 137 miles on it before it keeled over) I'm going that route also. I plan on going with the internal voltage regulator unit also. My question is- what to do with the current voltage regulator already on the bike. Do you leave it in or remove it? In my searches on doing the poorboy, no one has said what to do with it.
