onan generator

[pawpawboyce]

i just got my mh out of the shop and figured everything would be ok for a while. service worked on the information center and put in a new board to get 50 amp service working again since it would only display 30amps.

today, i tried to start my genset useing the start button in the the dash. when i engaged it, there was a loud shrill whistle noise for a second and then quiet. i tried the switch in the back and same thing. after 3-4 more tries with same noise it started. i ran it a while and shut it off. restart was successful. WHAT WAS THE LOUD SHRILL HIGH-PITCH NOISE? any comments would be appreciated.

The teeth (gears) from the starter bendix are not engaging with the flywheel. If you are lucky the flywheel is not damaged. This problem could be from a sticking bendix of something as simple as the mounting bolts of the starter need tightening. Salt air (rust) could have caused the bendix to not engage. Do not continue using it.
I did a quick search.

Onan Emerald Plus won't start

i've been checking out more systoms and i think my genset is trying to tell me my 6v batteries may be weak. with coach ignition off, i push the dash start button for the genset and all i get is a shrill whisstle sound at the power center located in the mid coach. still with the ignition off, i switch the above courtesy light on and it is very dim.
now i go and turn on the ignition, start the coach wait about a minute and the genset starts. runs fine as long as i wish and then i turn if off. the only thing i haven't done is enter the coach go back to the power center and press the check house batteries button to get a reading. i guess that will be tomorrow. it's a shame to go for service at the rv shop and then something else goes wrong after i get it home. has anyone had this shrill whistle sound off in the power center?

well, the problem is solved. coach batteries are shot! the shrill whistle sound was the propane alarm trying to tell me there was no power. the alarm is right below the fridge and i finally zeroed in ot it. the dim lights, and the fact that the onan wouldn't start was all evidence of bad batteries. while my mh was in service, the crew/someone left the bathroom vanity lights on for days finally draining the batteries. thus the reason the mh had to be jumped so i could bring it home. the regular 12 volt batteries survived, but the coach batteries didn't make it.
