Hello all Gottlieb System 1 Owners!

I'm repairing a Gottlieb System 1 Count Down from 1979, with some CPU issues, I'm wondering if anyone owning an operational system 1 could do a couple of resistance measurements across C16 and C17 for me out of interest? They are the +5V and -12V filter caps on the CPU, I'm intrigued to know as my reading across C16 seems way to low?

Many thanks for any help in advance

And here's a picture of the two caps on the CPU I'm talking about:

I have a Roller Disco (System 1), but boards replaced with Pascal boards.....did you try posting your request on "Home for the Gottlieb SYS1-SYS80B guys, Yep it's a club " thread?
