A relay coil with two windings and three lugs? Interesting. What's it for?

/Mark

2.5 sounds close enough to being right for part of the thing.

below is the schem. The kk-3316's are more-or-less like solenoids with eos switches - adding in a higher resistance hold coil to reduce power consumption.

the kk-351 is .... interesting.

the other thing ya need to know is a series relay switch will power the 1000 point relay.

it appears to be making sure that if the target or lane rollover switch closes long enough to trip the associated trip relay, you will get your 1000 points.

ok, you're gonna want more schem.

not shown this time is the 1000 unit step-up solenoid is directly powered by a 1000 point relay switch.

based on your video, the circuit keeps the 1000 point relay powered until the activating switch opens while lowering the current so the trip relay coil doesn't cook.

bad news tho is if a ball sticks in the rollover lane, that'd keep the 1000 unit solenoid powered and fry that instead.

if the high resistance half of the kk-351 is bad, you'd get the machine gun scoring lasting as long as the rollover / target switch was closed.

at least that's the theory at the moment ... anyone see something different?

per the schem, the two coil resistances on the kk-351 are 1.9 ohms and 83.1 ohms. I dunno how the thing is physically made, but the lug with the white-blue wire is common, so one probe there and poke the other two lugs to see what you get.

the pacific pinball museum's king rex schem isn't great, but I'll clean it up as best I can and get it to the ipdb. It usually takes them a few weeks to process and get it published.

if you're still in the game, can you see what the coil part number is for the ball count unit ... I think it's E-184-205

also the ball return solenoid ... E-184-213?

or if you have a readable schem, are those right?

I need those to finish the schematic cleanup.
