Question Newb with a generator question

[Cbc8]

Hello all,

Thanks for the add to the forum.

Had a 30 TT for a few years and loved it. We had a buddy who bought a class C Thor majestic from Cruise America and had nothing but awesome experiences.

So we sold the TT and got a 28A Thor majestic. Overall it’s been a good rig. We’ve had it about 2 seasons now.

first winter we had it the batteries die. After that I haven’t been able to get the generator to run. I fires up, runs a few seconds and dies. White smoke comes out of the exhaust. I keep getting a code 45.

So far I’ve replaced the carburetor, fuel pump, fuel filter, spark plug, fuel line, air filter. I’ve also replaced both batteries and have a full tank of gas.

The code 45 (according to Google Gemini…I know I know don’t flame me too bad) says it might be the brushes. I’m tired of throwing money at this thing without it being fixed and I know to get to the brushes I’m going to have to pull the generator and a bunch of stuff off it.

I’m looking for some sage advice lol. My local Cummins place said it’ll be $230 an hour and a minimum of 4 hours for diagnostic. Heck that’s almost 1/4 a new one with a 3 year warranty.

Looking for some help

Thanks in advance!

Also, we have a trip planned in 5 weeks going across the country with our 5 kids and 2 dogs in it….soooo I need to figure this out asap hahaha

I think it's too late for sage advice as you've kept throwing parts at the problem rather than get to the root cause. Try to find an independent diesel mechanic, they're every bit as good if not better.

Pardon the ignorant question….i know Cummins is mainly diesel however the generator is just gas….are you saying a diesel mechanic would still know his way around a regular gas Cummins engine/generator?

Apologies, I saw Cummins and I immediately thought diesel. I think your options just opened up as many small engine repair shops should be capable of the fix.
