Just brought home my first Gottlieb EM - a 1963 Flying Chariots. I've got 3 other EMs, 2 Williams and 1 Bally so I'm familiar with them, but have a few questions on the Gottliebs.
1. Are the hold type relays typically mounted with the coil lug plate end where the coil is screwed to the bracket? I have one relay in particular that is buzzing loudly and it looks to be the only one mounted with the lugs to the inside. At first I thought it was merely misassembled but no, it's made that way. It is, however, a replacement coil so perhaps it's made wrong?
2. How do Gottlieb EOS switches work on the pop bumpers? On this machine they are dual-blade, as usual, but have only a single wire attached to one of the blades.
3. Are there any adjustments to control how far the digits move on these so-called "Rat Trap" score reels? I have one where, when it resets, the 1's position zero is about half a digit too low in the window. All the other reels are good. I'm just wondering if it's worn out or if I can tweak its position.
4. How are the old dome style, non-active bumper caps typically held on? Mine seem to have a cotter pin stuck through the back edge and into the bumper body but that's it. Is that normal?
5. The backglass has no lift channels. Is the mechanism panel intended to pivot out from the back of the box?
6. Back to the relays - are these usually mounted with rubber or cork washers? I have some that are and some that aren't and some that look like they once may have been Is it variable based on the coil?
Thanks in advance for any guidance on these. I'm sure I'll have more questions as I move along. The game mostly plays, but something is getting stuck on during play, appearing to be associated with the red and purple bumpers, that I need to track down. It's hard to localize the sound but I think it might be coming from the reset coil bank. Time for some schematic reading now...
