RF/Card Whiz has three AS style relays. Which one are you working on.
The three are...
Bonus unit
Double Bonus Score Control
00-90 Unit
I suspect you are talking about the I relay, which scores bonus points. It gets a lot of work.
Replacing it would be difficult, and even if you found a replacement, it would need to be reworked too.
Take it apart slowly...clean...reassemble carefully. It's not that hard. Tuning it to work correctly is the tricky part. But with enough futzing...you'll get it.
