SOURCE: Cummins ISB 5.9 in RV ,seems to not have any power starting out

The turbo on those engines are not electronicaly controled. You have a boost or exhaust leak. Don't give up on a Cummins. Good luck..

Rv onan rv runs but now makes a rackett when running was real quiet


Contact www.advanced-power-technologies (Cummins Dealer) with exact model and spec number. Also there are cold weather options, and cold weather models. Many people buy the RS units of the net, only to find they have been stuck with warm weather models, and they don't start. Does it show a code, or a code 45.

If it runs while start button is pressed but stops when you let go?
Check the rotor bruhes, slip rings are clean on the rotor. If you want to get deeper check and ohm the resisitance of the rotor, and stator both for continuity and ground shorts. Check plugs and wiring on control board. Failing that replace control board

ONANS ARE PRETTY QUIRKY AS IT IS NOT CONSUMER FRIENDLY. THE GENSET IS DESIGNED FOR ROUTINE AND SIMPLE MAINTENANCE PERFORMED BY THE OWNER, AFTER THAT, U WILL NEED TO TAKE IT TO THE NEAREST DEALER OR CUMMINS DIESEL REPAIR SHOP.
