Looking for a little bit of direction diagnosing an issue. Game had worked for a good while bit but recently wouldn't start a game. Motor just continues to turn.
I pulled out the score reel and cleaned/adjusted all. Nothing notable there.
I ran through the relays verifying adjustments with the manual. Nothing jumping out here.
I noticed my low line 10a fuse was blown. Pop in a other fuse and it blows as soon as power is applied.
On power up the following happens.
Start and Coin relay activate. Left missile motor also starts turning. (It appears this motor is the primary motor like in a pinball machine)
Then coin reject relay on coin door actives
Then lock relay and timer control relay activates.
It stays in this state perpetually.
Poking around a bit if I activate the coin in switch it sometimes sort of starts a game. I get sound and the missile buttons work.
