Reg failure is pretty common when these gens sit a long time. From what I read here ,no load is required to kill reg. I've been on this site for 8 years, I have a similar design 7NHM gen. I believe connector on your BGD reg is/maybe different than one on BGE/NHE (Elemerald) regs. They are a very good company and even have a 2 year warentee on their regs. If that is good then likely reg is dead.I recomend Flight systems for a replacement AC voltage regulator. Sonmething like 7VAC out the B1,B2 leads (bat charging leads. If good, apply 12VDC (car bat) to F1-F2 lead ,should get: Rotor should be ~ 20.25-24.75 ohms, and no continuity to frame. with engine off measure resistance of rotor (F1-F2 leads) at gen connector going to reg. Typical for reg to die if gen sits a long time and sliprings get a coating then it's run without FIRST cleaning slip rings.īefore replacing reg I'ld test rotor/stator windings. I'ld make that switch a multi-contact one so it can also hot wire engine to run That way I can keep reg safe/off while I run engine so I can touch a pad to slip rings to clean them ( let engine do the work). I plan on adding a switch to pin 7 of voltage reg on my very similar design 7NHM. I believe connector on your BGD reg is/maybe different than one on BGE/NHE (Elemerald) regs, talk to FS they are good and will know. They are a very good company and have a 2 year warentee on their regs,and much more reasonable on price than Onan. If that is good then likely reg is dead.I recommend Flight Systems (FS) for a replacement AC voltage regulator. Look in service manual for wiring diagram and numbering of reg connector. When disconnect car bat windings will make ~ 1 inch arc, so don't hold the wires or you may get a BIG Dangerous shock, much worse than touching 120VAC. Something like ~7VAC out the B1,B2 leads (bat charging leads. ~ 40-50 VAC out the T leads (120V AC leads, ) ,hot wire engine so it runs, apply 12VDC (car bat) to F1-F2 lead ,should get:

With engine off, AC voltage regulator (reg) unplugged, measure resistance of rotor (F1-F2 leads) at gen connector going to reg.
