New information on genreator

I've been a member for 12 years and had the same Gulfstream Vista Cruiser all that time.
Recently I was trying to start my propane Onan 2500LP genset and it suddenly quit cranking. I took it to an Onan service center after replacing the coach battery and tracing the wires as best I could without finding anything.
They dropped the unit out from under the floor and tested it, it cranked perfectly. So, they checked the battery wire and found a small (1-1/2" x 3/4") 50 amp inline circuit breaker over by the water pump.(that's 4 feet from the battery)
So, I learned a $450.00 lesson (they only charged me for 3 hours and had 6 in it) that the generic books that came with my van, said nothing about the existence of this breaker.
Frankly I would have never thought this little piece of plastic was a circuit breaker.
My genset has 59 hours on it and looks like new and now runs like it.

    The first big lesson I learned is that what the client tells you is usually in good faith, but don't rely on it at all. Recheck everything. The OP tried to resolve the issue and I admire that. But, he's not a professional. It isn't like another tech at the shop stated that this list of items were checked, so the second tech shouldn't do it over again.
    If I understand correctly, they actually worked 6 hours to find that it wasn't getting power! Glad it wasn't a complicated problem!
  • reading through- the owner tried to check it himself.


    it could be that he gave information or direction leading them to drop the genny.

    sometimes it is better to saw ' the genny cracked and then stopped cranking' and leave it at that


    then they start at page 1

    if the owner says "i traced all the wiring..."

    then they assume his checks were good

    Your posts are always so positive, and uplifting. :R
  • For 8 years my inline fuse would blow while trying to start the generator. Finally this year I replaced the fuse and have had no further troubles. I should have fixed it long ago.

  • I agree, no power to the starter so they pulled the generator? The didn't do a very good diagnosis.

    The repair dealer didn't install it in the RV, how would they have known it was there?

    Very true, but any troubleshooter that has a starter that doesn't turn over should first check for power. If the breaker was bad there would be no power to the genny. No need to pull the generator in that case, so they did not do a good job and shouldn't have charged for the removal, IMO.
