    after chasing multiple dead ends thinking my onan emerald plus generator might have carbon build up and too stiff to start, just determined I had insufficient amps at starter. Got wiring schematic from Winnebago (very user friendly) and it looks like problem must be at R/V battery disconnect relay. How does it function and can I test it in any way. Generator runs fine using chasis ground side if I supply 12 volts to genetator start switch directly from battery. Any thoughts or do I just replace the battery disconnect relay and hope it works.

    Attempt to flash the unit. Ensure you have good batteries and good connections and good grounds. Your manual should cover flashing.

    I have an Oman generator model number 5.eghem/340. The motor runs great but not generating any electric. I took the cover off where the wires come out of generator and no power to terminals. Based on this is there any common problem to check before taking to a repair facility and spending a huge chunk of cash?

    Sorry, we would recommend contacting the manufacturer of the pump to see what range of serial numbers were used for pumps on that Onan 7000.

    Need to find the nameplate somewhere to find at least what the generic engine is. It could be on the underside of the sheet metal or in the mobile home manual. Sorry, we can’t help more.

    Looking to reduce our inventory of Onan and other Generator parts, we are a Generac Dealer and provide service for Gnerac and all other brands. Over the years we have purchased parts for jobs that have been canceled or have made the mistake in ordering the wrong parts. These parts have outgrown our stock needs and we are looking to cut back. We are trying to sell as bulk. Email me for inventory lists and pictures.

    Thank You.
