Hamilton GoldLine controller

[Davidson]

Looking for a new or used controller. Part# 49-9684 version 4.0. Mine is acting up and need to send to Hamilton for repair. They are out of stock on new ones 16 weeks they said. Anybody point me in the right direction?

I have two large plastic bins full of Hamilton parts. I'll try to remember and look through them. Bump your post or PM me if you don't hear back from me soon, I have a terrible memory.

What's yours doing that it's acting up? I have one I rent out.

It will just start talking nonstop prices and wash packages. When I turn off and back on it resets the memory and wash packages go to $1. Hamilton says it's probably the battery and not field serviceable. Its done it 3-4 times in last few weeks.

I'd try replacing the Battery module first . The battery module is a ST M48T35-70PC1 it plugs into the board. It's located to the left of the v4.0 EPROM chip when your looking at the controller.

 

[Davidson]

Thanks Randy I will try that first. Any particular place you'd recommend to get that part from? Is it just plug and play or will I have to reprogram anything other than wash packages?

You can get one from Mouser

Or Newark

When you install the new battery module just be sure to plug it in the same as the old one. You'll have to reprogram the controller after you install the battery module.

Thanks Randy I'll order today. Never reprogrammed before but surely Hamilton can walk me thru it.

Did this work? I’m having the same problem seems like!

I actually found a new controller and that fixed the problem.
