This is the old PRDLLAYO PB relay easy to check .Take a insulated screw driver and press the contacts down .If this gets the bus electrified ,then check for power to the coil .If the transfer relay checks faulty head over to Grainger .This relay is about a 30 dollar unit .

if yours are so much better...why aren't you selling them ? or better yet...giving busnuts a drawing and parts list ?

I can give you the Grainger part numbers and I have a simple drawing on the inside of the cover plate but I figured out the wiring by just looking at everything. I can't take credit for the parts, it was actually posted on the old MAK board 20+ years ago. Anyone remember JimNH? He was involved.

Sounds like you may have this figured out.

Mine quit last year and it was the controller inside the box on the generator.
It's a Kubota proprietary part, meaning not available from anyone else.
Seems it was over $400 plus shipping, which they were proud of too.

Hopefully, yours will be a cheaper fix.

He is charging you for the Houston traffic

I am a country boy. I can't stand going through the big city. I don't blame him,one bit and don't begrudge the man for charging the 185. Hopefully he is not on this forum because i would double that charge.

I train dogs on the side. People ask me to come to their house for private sessions. I tell them yes but my house calls are 1500 bucks. I do that just so I don't have to drive to them, they have to come to me.

I am glad the service guy talked me into just replacing the whole transfer switch box. I could have overnighted the printed circuit board to be fixed and they overnighted back for nearly the same money as a brand new box and switches. I think I'm skating by under $1,000. Not bad for having a problem off my plate knowing the buyer is going to have a good product to drive home.

Inquiring mind want's to know------- I can see where you would need 2 relays on this .These are 30 amp relays so you would need one for each side of your 240V line but where does the third relay come into play???

What new transfer switch did he install ?

I'm not sure what brand transfer it was about half the size that I had in there. I will look and see if there is a brand name on the box when I get to the house. I let it run for about 2 hours with all of the appliances air conditioners Etc turned on. That never missed a lick for those two hours.

You can by these xfer switches at camper world or online. They are in sale online right now for 148 plus shipping. I paid $225 through him. I couldn't drive to camper world or have it shipped here and save much money. I am dern glad to have found this mechanic. His number is going into the file. The whole ordeal was a telephone call and $750. I didn't want to spend it but sometimes you do what you don't want to do.

I have pictures of the transfer switch I made and has worked flawlessly for over 20 years of constant use. Unfortunately I used my smartphone to take several pictures and I can't seem to separate the pictures so I can post them. I have a new topic called "Make your own transfer switch" with my email address if anyone can help me out.

looks like a workable solution: anyone can convert to a parts list and drawing/diagram/schematic ?
