Liberty Classic Transfer switch
For those of you that have a liberty Classic. If You start hearing a clunk clunk when You plug into shore power. This post might just save You some grief. Mine started doing a couple of clunks before it would kick in. Eventually it just kept clunking and would not kick into shore power. And I say clunk because it is loud. Not a click but a clunk. It is the contactor kicking in and out. It is not a good sound and will give You that bad feeling deep down in the pit of Your stomach. You already know that feeling if You own a coach , Not good at all ! Initially I thought the contactor was bad. Turns out the timer relay is a weak link with a high failure rate. ( Found that in a post made by Mr Rowe using the search engine here ) There is one timer relay for the generator and one for the shore power in the transfer switch panel. They are interchangeable, took Me a few days to figure that out. The one on the left is Gen and the one on the right is shore. Different brands but they do the same thing. When My shore power quit I run off of batteries and would start the generator to charge them up. When all I had to do was swap the timers and shore power would have kicked in. You also have the same timer under the bathroom sink if You have air pocket doors. Which could be borrowed until You get one shipped in. It would be a good idea to keep a spare on hand.

I wonder if those of us with 24volt Liberty’s of similar vintage have the same timers. Where did you find these?

Same unit in coaches for a lot of years….

Dick,
I had the same timer go out in 2015. It was obvious then due to some black soot around the base. I got a refurbished one then from Radwell international in Lumberton,NJ. It had a 2 yr warranty and is the one that just failed @ about 20 months. This time there was no soot at the base. I went ahead then and purchase another new one in 2015 from another source. I will look for the receipt and give you that company when I find it. At least now I know that I have others onboard to use in a bind. If Your generator timer fails on the road , Switch them , and You are in business.Bsafe,
