Just picked up a Ship Ahoy and am having a start-up problem. Any other EM machine I have owned if you move the motor, it spins on it's own until the next 120 degrees and stops. Mine will not spin on it's own unless I spin it an inch or so then push the contacts together on the slam switch mounted on the floor beside the motor assembly. Then it will spin until it's supposed to stop as long as I hold the slam switch closed. If I hold the slam switch contacts together and move the motor it will spin and stop each 120 degrees. Holding any of the other cabinet slam switches closed does not do this, just the one next to the score motor. I don't know if all this has anything to do with my start-up problem though. Anyway the credit light is lit and the credit button does nothing, but lights are on. Also previous owner had rewired the coin door so no wires are going anywhere on the door, just runs past the door to the credit button. Any suggestions or links to schematics would be appreciated. I do have a very similar (Both 1976) working Gottlieb Bank-Shot machine right next to the Ship Ahoy so some comparisons can be made, Thanks!
P.S. Got both machines at the same time, my First Gottlieb's...

Are the bounce switches under the Playfield, behind the backglass, and on the coin door supposed to be normally closed also?

So the one mounted to the underside of the Playfield (see photo) is the only one in that is normally open, correct?

Well the credit button still does nothing, but now it will reset via the relay. All the solenoids fire but no points are scored except for the spinner. The Spinner scores points and chimes but nothing else, not even the rollovers either score or chime..

We have scoring and most everything is working, so I'm going to have to assume it's just a bunch of cleaning from here on out. There is what I could only call a mini stepper unit with 1 relay for controlling chasing lights. Does anyone know what this part is called, or where I could get some of it's internal plastic parts, or the entire.unit from?

I did find that "AS" relay on pinball resource. Mine seems to work when I actuate it by hand, but I don't even know when this relay gets energized. How do I know when this thing is supposed to do what it's supposed to do? Before the machine started working I could actuate this relay by hand and yellow lights would move around. Now I don't get any yellow lights at all. Does anyone know exactly how/when this is supposed to work?

You guys are the best! Thanks so much! The non working "AS" relay turned out to be a dirty Jones plug. Got everything working aside from a couple of light bulb sockets, which I found if I put a small "BB" of solder on the tip of the bulb (& a wire wheel on the bulb body) will fix 95% of the dim lights out there!
