Rebuilding Generator--is it worth it?
I'm at the Cummins-Onan shop, with my 1999 Onan 7500 Quiet Diesel generator. It seems that, when I started it this spring, there was a lot of clunking inside, so I shut it down. It wouldn't crank over after that. It gave a 33 code, Service Required.
I just got an estimate of $3,600 to replace a damaged Stator assembly, rotor assembly. and fan. It would cost an additional $1,750 to include a new inverter in the package, but I'll gamble that the old one will still work. By the way, there are only 987 hours on the genset.
I've used the generator a total of 3 hours this past year, so I toyed with not spending the money to repair it. DW said don't fix it, but after joining the Cummins club, we've gotten the price down to around $3,000, so I decided to go ahead with the fix. For what it's worth, about $300 of cost is for removal and reinstallation of he generator.
It's painfully obvious that neither I nor any prior owner, has run the generator monthly, as recommended by the manufacturer. I figure, for the cost of these repairs, I could have exercised the genset for 2 hours a month for more than 13 years. Another expensive lesson learned.
But the question was, is it really worth repairing a generator on a 19-year old motorhome. DW contends that most folks will simply plug in somewhere and won't use the generator, just like us. For my part, I prefer that, if I have a generator, I want it to be operational, even if I seldom use it. I must admit, however, that, had the cost to rebuild been a little higher, I wasn't going to spend the money.
The moral of the story: EXERCISE YOUR GENERATORS.
