My name is ***** ***** I am going to assist you with this.

Ahhh, a fellow Minnesotan ( I was born and raised just outside St. Cloud).

What is the full model number of the genset, exactly as it is written on the data label?


Customer: replied 2 years ago.

I can only make out a few letters. It seems a few were rubbed out. It states: 4.0 BGE-???00

S/N: H870918501


Hope this helps.

On a BGE, I really need the rest of those numbers. There are 21 variations of the BGE - and they are not all the same.

But for the most part, I am not convinced you have a genset issue.

The BGE series units will not keep running if they are not producing power.

Exactly where and how did you check for voltage coming out of the genset?

Did you make sure the breaker on the genset was turned on (you didn't specify if you checked the genset breaker or the main breaker in the coach)?

Does your unit have an automatic transfer switch, or do you have an onboard receptacle that you need to plug the shore cord into for genset power?
