Hello Gary and
. We are glad to have you join us here and we look forward to reading of your adventures and experiences. I am sure you will enjoy the website and forums.
I would suggest that the electrical connections of the generator be checked and tightened if needed at the junction box and in the transfer switch first. If power is still intermittent, you will need to determine if the generator is the culprit or the transfer switch with a voltage reading from the generator to the input of transfer switch. Many of the Alpha's have a built in Surge Guard. Make certain that you wait for the time delay (2 min. 56 seconds) for power to be sent through to the coach.
Good luck, stay safe and keep us posted.
