Looking at the manual it seems pretty archaic.  I know my bus is not charging right now but the PO messed pretty hard with the electrical.  I never have had too much luck in the past with generators especially the regulators,, and have always replaced them with alts.  Does anyone still run the gen and reg or is it too much trouble?  Seem I would not even need that high an amp alt as the bus is just doing light service and all my fixtures are propane.  Thoughts and input as always appreciated.  Patrick. 
p.s. is it stupid to just rig up a car alt and leave it at that?

My 4104 was converted to a 160a truck alt when I bought it and I have been very happy with it even though 160a is extreme overkill-60a would be more like it.

The old gen is heavy, has oil and water hookups, takes up a lot of engine comp space and is probably impossible to get parts for. I can't think of even one reason to keep it. If you do you are welcome to my old reg which was still in my bus.

Unless you need to charge a huge bank of batteries 60-100a should be plenty. I have two Gp 31 house batteries and two Gp 31 start batteries so I don't need anything like the 160a I have.

I'm still running the original gen and regulator on my 04 and mines not charging right either. After 2 to 3 day trips I notice my volt meter showing low batteries so I put the charger on them. I bought an accessory drive last year so I could convert to an alt, but haven't got around  to installing it yet. I see no reason to keep the old stuff as it's a constant maintenance headache.

Highly recommend you change to a truck type alternator.  I know you can get a new 130-160 amp Delco, or Leece-Nevil for around $250-$300 new with the regulator built in.  Course these are negative ground-I know the 4104's were positive ground, but many were converted over to negative ground.  Personally, I would switch the electrical over.  Good Luck, TomC
