I have a 2010 Newmar Canyon Star 3920. Pulled in today (in 100+ heat) turned on the generator and then the a/c. It ran for awhile and then nothing. I now have no power at all ?? Everything was working fine earlier today and yesterday.

I checked the obvious things like circuit breakers, battery disconnect switch etc. All ok.

Any suggestions ?

generator quit running & won't start ?

or its running but NO 120v ?

what about your 12v lights etc.

if you have NOTHING, NO 12v power,

#1 bad battery cable connection, positive or negative

#2 blown catastrophic "main battery fuse"


Options, always have options, and the journey goes much smoother

Hi,

There is a circuit breaker on the generator, that might have tripped? What about the fuse inside the inverter? Do you have 120 volt power from the inverter circuits?

When you say no power, like asked above, do you mean no power to the engine? No 12 volt power, or just no 120 volt power?

Have you pulled into a campground and tried to use shore power?

It is possible that your generator was a bit overloaded by the heat, and this might have tripped a 30 amp circuit breaker on it, because the air conditioners do use more power when it is warmer outside.

start with shore power. if that works . how about inverter power? if that works start with gen. see if it puts out . then the transfer switch. does it click when shore power is hooked up? follow the voltage from generator to your master 120 volt circit panel. some place in the line up you are disconnected.
now if gen dont work ... get an expert.

assuming you have a voltmeter.

again check battery voltage . then start gen. see if voltage on batteries increase a bit. try it on shore power... that indicates you have 120 volt power . wreite for moree questions.

Is this a gas Onan?

Does it have 2 circuit breakers on the generator?

Might also have 4" square box in the gen compartment with two "pop up" circuit breakers. Push them.


Yep, actually drove to all of these places---in the last eight years. Missed Rhode Island and New Jersey.

Luke, Yes, it does have 2 circuit breakers on the generator. Didn't see the 4" square box you talked about but will go now to have another look.

Am at an RV Park now - plugged in - have power ???

Thank gawd for a/c !! It's already 82F and it's not even 10:00AM !

But still don't know what the problem is ??

Talked to a local RV service guy - can't get anybody until Tuesday 'cause of the holiday weekend.

UPDATE: The local RV Service tech guy came out this afternoon - shudder to think what that's gonna cost being it's a Sunday on a Holiday weekend...

He located the 'wire' that he said is the source of the problem and said now has to follow it back to see where it is shorting out. Seeing as it's 102F here right now he suggested that I find the wiring diagram for the 'house' part of the Coach as that will help him follow it back faster. I have to bring the rig into his shop Tuesday morning where he said he will find the problem and fix it.

I've gone through (quickly) the mountain of Manuals that came with the rig. Any suggestions where I would find this wiring diagram ????
