Jungle Princess- At power up the spinning unit in the bottom of the cabinet keeps spinning and never stops. I was thinking bad relay but wasn't sure.

Jet Spin- Sometimes can play for 10-15 before it happens sometime 1 min. It reset full game reset. Lose flippers and everything. Also I can get it to say more then one player but it doesn't change between players.

Americana shuffle by Chicago Coin- Can score a strike no matter what. Two of the pins wouldn't move fixed that but still can't get it to score past eight. Played with the switches all of them seem to be working first ally I have worked on so any help would be great.

Hot Tip- Trying to locate a place to get a IC chip for one of the boards

Jr. Pacman- same thing, trying to locate a place to get IC's U2 and U4 are bad.

Last thing...

Dixie Narco- Bill acceptor, trying to get new belts. Any ideas?

On the Jungle Princess:
When you power up the game, is it doing this before you press 'start' ? It's trying to find it's 'home' position. The way it finds it's home position is once the score motor is in the correct place, a switch or switches will open or close telling it to stop the motor. Without the schematics I can't tell you which, but if you carefully clean all the switches on the score motor assembly it should make it find the home position. The switches are probably closing or opening alright, but they're so dirty that it doesn't see the closed switches. (it thinks they're open since it's not conducting electricity through the dirt!). To clean them you can use a business card or something like that, just rub it between the contacts to clean the grime off of them.
