I have a jackpot relay on the reel assembly. I have 2 red and 2 yellow on the 2nd switch down. Pic for reference.
double wires mean that wire connects more than 2 things together, so you have a daisy chain. The end spots in the chain have a single wire and all the rest have double wires.
to verify, stick paper between the contacts on the switch with the yellow and red wires. The bell should only ring for a 7 and bar/5 win as those are handled via a different circuit thru the reel wiper boards. On an 809-N, they actually cheated a bit and connected some wires of different colors together on the reel 1 wiper board to make that happen. This was rarely done directly, but using a jumper to tie wires attached to different lugs together was a little more common.
the docs don't say the wire colors connecting to the 100 and 200 lights, but they are connecting back to wire 45 on the payout relay switch eventually.
below is the reel wiring diagram for the 809-N and others. It's not clear if the 10-2 wire is directly connected to whatever color is on the "200" lug or if there's even a different wire color on that lug. 100 and 200 aren't wire id codes, they are just labels connecting lugs to rivets.
the issue is the bar jackpot relay stays powered until a coin is dropped, so if ya walk away it rings forever.
typically the bar jackpot (bars match) relay only powered for high payout bar wins, but on a lightning game with few pays, it powers for all single and mixed bar wins and doesn't power for 5/bar wins ... but they rang the bell for 5/bar wins differently.
there doesn't actually seem to be much purpose for the bar jackpot relay on a lightning game with your pay table ... they coulda easily handled the bell ringing with reel board wiring. A game that had multiple kinds of bar and paid for mixed bars would use the bars match relay to switch on a higher pay. e.g. mixed bars may pay 10 but something like matching single bars would pay 20, so the bars match relay picked which trace on the payout counter was powered. The reason the relay is even in there is so they could build more-or-less the same machine for any 809 variant and hook up the relay differently depending on the pay table and game rules.
