Took all day to change two fuel filters, get a replacement alternator and, later, a replacement battery. Last evening, the GMC began sputtering and it got so bad, I decided we would likely not make it home. Figured ethanol had loosened more crud in the fuel tanks/lines. Stopped in Baytown, only 32 miles from home. However, the alternator-used in my trailer that I replaced the O'Reilly one with, was not putting anything out, so we were running only on the new battery-definitely would not have made it home. Found, fortunately, an RV park in Baytown so had roof air.....had no water all week, the pump did not work and I blame that on the RV shop which may have turned it on by accident and it ran dry and also ran down the deep cycle batteries. Then, upon hooking up in Patterson, a copper line separated from a copper "T" and the plumber said he could not fix it. Also, the Onan did not start-fuel pump not pumping. JimK said use a auto store replacement, but I will look for an original Bendix. Thank God the dash air now works better than it ever has so we were okay.
The little test gauge I have shows the new alternator putting out at 13 volts which it regards as "low". Somebody update me on what that is all about. The engine turned over with a grunt first rather than the usual grrr,grrr,grrr! Yes, I did get the alternator pulley changed.
Well, it is time for a shower and a late meal before heading out in the GMC for College Station Texas tomorrow and my 50th college class reunion. Wish I had been smart enough to study mechanical engineering.......Thx, Michael at GEMRECS
Fuel tanks are coming down after that!

Yes Michael, 13 is low. It should be up around 14.2V. Unless it's extremely hot out then it might taper down into the 13s but 13.0 is low. Good luck.

did you try "jumping " the fuel pump on the control board?

Hi, Michael.
What sort of "test gauge" did you use to check the alternator output?
As somebody else answered, you should be looking at alternator
output of around 14.2 VDC. You need to look at that voltage with a
reasonably accurate DIGITAL voltmeter/multimeter.
My 50 year college reunion would have been last year, but I have
never heard of one being held. I am NOT on any of their begging
lists, thankfully!

There is a fuel filter in the bottom of the Onan fuel pump. Any reason it wouldn't be clogged up just line your "prime mover" fuel filters?
The Onan pump is rather simple. Besides the filter, it has a piston and two check valves. IIRC: Those are the only moving parts in it. I have had good luck with disassembly and cleaning with carb cleaner. I would try cleaning before replacement.
