No power between Transfer switch & Main breaker on Generator

[tewheeler]

I am new to RV experience and this is my first post. Hopefully it will go well.

I have a Onan 4000 generator that runs fine and I tested the main breaker and it is good. Power on the line side and on the load side with breaker on. I am not getting any power to the power transfer switch inside the coach. No power detected at the in from generator contact points. Where should I be looking? Is there another device between the main breaker and the power transfer switch? Thanks in advance for any help provided.

Got it!! it was a short in the wiring in the junction box. Fixed it and now all is good!! Thanks to everyone.

Not sure you are describing you condition properly. No power to main panel from transfer switch is a result of 1 of 2 situations, 1 Tripped breaker on genset, or 2 a bad transfer switch. The first is easy to check the second is a little more dicey. Do you have 110 power with shore power connected?

Check the control fuse on the genset?

Do you have a transfer switch or do you have to plug the shore power cord into an outlet in the power storage bay?

This is what I am deducing......

Gen runs but nothing from transfer switch to MAIN panel

So Gen breaker(s) tripped........or transfer switch stuck on shore power side

Maybe the generator breaker at the generator is tripped. I was having trouble reading your post about which main breakers you were talking about. JMO

By "main breaker", are you talking about the breaker on the genset? Normally, there is nothing between the genset and transfer switch, but there is a junction box usually, with wire nutted connections.
