Onan 4000 Generator Emerald 1 Wiring Diagram - Welcome, thank you for visiting this simple website, we are trying to improve this website, the website is in the development stage, support from you in any form really helps us, we really appreciate that. We will share this website for you articles and images of wiring diagrams, engine schemes, engine problems, engine diagrams, transmission. RV Emerald Plus. ▫ Vacu-Flo cooling system plus Thru Flow generator. BGE: (LPG) Onan patented LP vaporizer with demand regulator. See Installation Manual for details.
I have an Emerald Plus out of a 1993 motor home with a bad voltage regulator. The slip ring resistance was high so most likely needs cleaning as well. The generator seems to run well, though I have to choke(?) it to rev it up to speed at first to get it going, but it puts out around 150 Volts, 60 Hz.
I was quoted almost $400 for a new regulator from Cummins, and I've seen flight systems ones for $225 which still seems like a lot for a handful of components.
I don't know much about Onan generators - getting the impression they are pretty finicky and expensive to service.
Has anyone seen the circuit diagram for any Onan BGE AVRs and the pins? I'm curious whether I can bypass the shorted pins (test procedure says they should be open) and workaround the problem with an external component.
