Transfer Switch replacement

[Rodney T]

I have a 2000 Winne 35U

The Transfer Switch failed it is a Todd Engineering PS245LK (Todd Engineering is out of buisness)

I have received 2 reccomended replacements

Parallax ATS 501BP ~ $180.
Parallex ATS 5070 ~ $100

Any words of wisdom they both have 50A contacts ?

If one has a timer in it, I would go with that. Also, the best way to kill a transfer switch is to operate it under a heavy load. Before changing, turn off all high current devices (air conditioning, washer, hair dryer, space heaters, welding rigs, etc.).

Lyght engineering makes a transfer switch that looks just like the old Todd. It uses dc relays, which are quiet. I chose to go with a heavier-duty unit, but it does hum.

Here is what they call a Surge Guard transfer switch and surge protector in one unit.
Some spec's on SGTS.
SGTS WOULD BE IF YOU DIDN'T ALREADY HAVE A SURGE PROTECTOR TO PROTECT YOUR ELECTRONIC'S IN COACH.
Notice the difference in price?
Here is a few more.

I have the Surge Guard transfer switch and power line monitor and can recommend it. It's pricey, but you get a good switch and top of the line power protection as well. And the remote display is handy too.

Let me add a link. The LPT50BRD with 8x11x3 box is like the old one I have. There is a troubleshooting guide with a wiring diagram so you can see if that's what you have. If the contactors look okay, perhaps all you need is a time delay, which would be a cheap fix. If I'd seen this years ago I might have saved a lot of money.
