Hi All,

I'm pretty good at fixing SS and DMD pinballs, but EM's are still a bit of a mystery to me, however i'm determined to understand them!!

I bought a 1962 Gottlieb Tropic Isle. Replaced the mains wiring that was all completely perished, fired it up and adjusted a rollunder switch (relay was locking on) and pop bumper switch (also locking on) and it appeared to function OK. I say OK, meaning i triggered switches with my finger and it would score and fire pop bumpers, slingshots etc. Every time you hit the start button it would reset fine and all the score reels would zero every time, and it would release the ball from the trough.

Now not sure if this is related, or not, but the first time (after about 6-8 times of the above) i allowed the ball to drain, it then went into a continual state of hte motor turning and nothing else.

So now when i power it on, it just spins the motor. It also holds in the trough coil in (ie: to release balls) - i have cleaned the 3 stack switch at that coil and it appears to be adjusted correctly wiht no difference after cleaning.

Other details that may or may not be important - if i advance the socre reels, they (all 3 of them) always reset back to zero, so it appears to me that its missing a step/connection/switch state during the reset sequence after the score reels reset.

I don't have a schematic yet, but will hopefully be recieving one soon, but if anyone has one, feel free to share!

Thanks in advance

In this age of gottlieb machines, the reset relay tripping from a series circuit of closed switches on the score reels all at zero position should be the last step of the reset sequence.

Does this game have a DB/Reset relay in the trip relay bank? I think that relay is reset along with the entire trip relay bank when the replay button is pressed and the S/Start relay fires. In other games the DB relay sends power to the Score Motor and the Ball Release coil until it trips when all the score reels have reset to 0.

If you manually trip the DB relay does the motor stop? If so, one or more of the score reel switches that should close when they reach zero probably isn't closing as pinballdaveh suggested.
