stacisweeney Report post Posted August 18, 2020 Hey FMCA family, my husband and I are new RV owners and we had a small mishap with our generator. We have a 1997 Tiffin allegro bus with an onon marquis 7000 generator. my husband went to turn the generator off and thinks he may have accidentally hit the start switch while the generator was in the process of turning off. he also managed to hit some kind of 12 volt switch. since then when we go to start the generator it makes a horrible grinding sound. we've checked the oil in the generator and the oil is fine. does anyone know if there is anyway for us to fix the generator ourselves or do we have to bring it to an rv repair shop?? keep in mind we have an appointment with a repair shop for September 1st but itll take 5 to 7 days just for them to look at Rv once its there and we are keeping our eyes on a system that may potentially make it into the gulf this week which is of some concern as we live in louisiana Share this post Link to post Share on other sites

First question is does he have some good mechanical skills? Like doing his own lawn tractor or mower service. Rich. Share this post Link to post Share on other sites

stacisweeney Report post Posted August 18, 2020 Hey Rich, Thank you for responding. He does have mechanical knowledge and know how. He's worked on lawn equipment before and actually has some aviation electronics knowledge. Would this be a somewhat easy fix ?? Share this post Link to post Share on other sites
stacisweeney Report post Posted August 18, 2020 I should also probably mention its a gas generator and not diesel. Share this post Link to post Share on other sites

Remove the starter and check the gear. Share this post Link to post Share on other sites

desertdeals69 Report post Posted August 18, 2020 On mine the starter gear assembly was broken so I priced the Onan replacement parts and they were fairly expensive ($60). I looked on EBay and found a complete new starter with the drive gear for half that. It was an import. I ordered it and installed it and it works fine. I machined some replacement parts out of aluminum and repaired the original starter which I carry as a spare now. Share this post Link to post Share on other sites
stacisweeney Report post Posted August 19, 2020 Thank you so much desertdeals69 wow thats pretty cool that you can machine some of the parts. We ordered the starter assembly today from Amazon. My husband feels fairly confident he can fix it himself Share this post Link to post Share on other sites

With your feedback and DD,s feedback I feel the job is in good hands. One should have a meter that checks the AC frequency and ac voltage. Keep one plugged into an AC outlet at the kitchen counter where it monitors the generator and shore power when connected to the grid. Just a quick glance offers good line condition information. Stay safe and welcome to the RV life stile ! Rich. Share this post Link to post Share on other sites
stacisweeney Report post Posted August 19, 2020 Thanks so much rich. There is actually a monitor mounted next to the a/c control that monitors everything. I check it all the time lol. I do really appreciate everyone's input and cant thank yall enough. The new starter should be in on Friday. Share this post Link to post Share on other sites
