I never thought I would own a pinball machine...until a relative of mine showed up on my doorstep a few months back with one in tow. It's a Chicago Coin Hee Haw. He said he didn't know much about it, and it wouldn't start up when he got it.
To make a long story short, I've read a lot about how to repair the machine, and I've done a lot of the standard stuff already (changed out the rubbers, fixed up the flippers, cleaned the playfield, installed new lamps, tested the fuses, etc). I'm at a point, however, where there are several issues that I really don't know how to fix. Since I'm completely new to this I'll try my best to describe what's going on.
Issue #1: The machine wouldn't reset the scoring reels when I turned it on. I worked on all of the reels, de-gunked them, and now both players 1 and 3 (on the same relay) will basically reset. Players 2 and 4, however, will not (also on the same relay). If I operate the relay for players 2 and 4 by hand when the machine is on, they will step back one at a time until they are fully reset. So the question is why won't the relay fire to reset them?
Issue #2: Sometimes when I turn the machine on to play, everything works. Other times, the following items will not work: Bumpers lighting, 1000 point when lit bulb (front center target), ball saver popping up between the flippers, and the match lighting up at the end of the game. For whatever reason, if one of those isn't working, none of them work. If one is working, all of them work. If they work it's usually when I first turn the machine on and lasts for the first game or two that I play. It never seems to "come back" the longer the machine is on.
Issue #3a: Neither the 100 point or 1000 point score reel works on player 1. When I tested the coils (which were both black), one read somewhere around 1 ohm and the other did not read at all (all the other coils read somewhere in the neighborhood of 5-6). The previous owner looks like they knew about the issue but decided to disconnect several wires from the reel instead of changing the coil. How can I figure out which wires go back where? Additionally, I have purchased two replacement coils (looked up the proper numbers, etc.) and have them in hand ready to replace. Is it ok to solder them in now even though some of the wires are disconnected from the reel?
Issue #3b: None of the 100-point reels work on any of the other players either. All of them have disconnected wires. So this is a repeat question of 3a. Additionally, the bumpers that register at 10 points each on player 1 register at 1000 points each on player two, so I'm guessing some wires are really wrong.
Any assistance you can give me would be wonderful. Remember, I'm new to this, so I probably won't understand what you're telling me to do at first, so expect some questions. Also let me know if you need pictures and/or video of something specific and I'll do my best.
