SOLVED: ATS-5070 Transfer Switch - Shore Power Only

[KendallP]

SOLVED in post #14

Hello,

This is in my grandfather-in-law's 2004 Winnebago motorhome. I'm guessing it's original. Generator is an Onan 7500 diesel and appears to be running great. No one can remember when the switch worked last. Only shore power is getting through to the coach. No genny power.

I'm getting 120 at the switch's terminals from the generator, but none at the output. The delay is supposed to be 20 seconds. I gave it 10 minutes.

Things are pretty tight in the power locker. Is it worth cracking open the old switch to inspect the relays? Or maybe a loose wire? Or is it just time to landfill it and replace?

If I replace, I can get an ATS-501 still... which may be the direct replacement for the 5070. 200 bucks. I'm told a 503 might be more robust, but bigger for about the same price. I have basically zero play to work with in both the generator cable set and the output set. So a direct replacement would be ideal.

Or is there another unit you recommend that would be an easy swap?

Thanks. Yeah, I reset the breaker on the genny numerous times before cracking the transfer switch case and I have 120 from it at the transfer switch terminals.

Should work and not $200!

Thanks, B.

But that one looks much lest robust than this one. And this one has 10 cables going in and out. Mostly big ones. 4 awg, maybe?
