Ribbon cables

[Celotine]

Got an intellivision today and the ribbon going from the power supply to the Mobo is corroded all the way thru 😩 Do replacements exist?

This thread has some good info that will give you some ways of fixing that connection.

Yeah I saw this one. I was seeing if there was a proper ribbon.

Ok I ran wires to fix the ribbon issue. I seem to have 18v on 1 rail. That doesn't seem right lol. Any ideas? I hope the ICs aren't blown now

This thread:

has a link to the service manual and a schematic. There are test points shown to check voltages.

~17v could be correct for one of the rails.

I see 16v unregulated in the service manual. With the mainboard disconnected I'd expected a little higher.

I was thinking that just now. Time to reseat everything in sockets. Maybe with some deoxit and see where that goes.
