First post on Pinsider for me, new to restoring pinballs.

I'm the guy that MaxAsh is helping debug the Kicker. I managed to resolve the issue with the 10-90 reel not resetting. Looking at the schematic, the reset signal goes through the UNIT RESET relay (circled in green) and gets to the 10-90 coil through the ZERO SW relay (circled in red). The ZERO SW relay is closed on all numbers except for 0. During reset, while the reel is on any number but zero, the RESET signal is controlling the reel turning. Once the reel gets to 0, the ZERO SW relay opens and the RESET signal no longer gets there. I ohmed out both the relays. The UNIT RESET relay was working OK. The ZERO SW relay was always reading an open, even when the contacts were touching. There was some hard white gunk on both contacts that needed to be sanded off. This resolved the problem and now the 10-90 reel resets. The ZERO SW relay itself is really beat up though and I will probably replace to avoid issues in the future.

The one open item on this is what is controlling the RESET signal? What is letting the game know that the reels are reset and that signal no longer needs to be fired. I have a couple theories, the 1-9 reel and the 100-900 reel both have 0-9 counters on them. I think when these counters get to "0", it lets the game know that the scoring reels are reset.

Thanks again to everyone for your help on this.

This is the next issue I have encountered - the 1000s scoring reel was not working at all. I pulled the reel assembly off its bracket to measure the coil resistance. Once I inspected it I noticed the wires from the coil to the coil base were either broken or cut. Connecting my multimeter to the wire stubs read an open. Does this mean the coil is bad or could the wires have a coating that does not allow for a measurement to be made? I attached a photo of the coil with the broken wire stubs.

Thanks in advance
