Hi Pete
I don't have a schematic for Champion, but the following is from a Gottlieb Surf Champ
On here the circuit is relatively simple:
A ball in the hole closes the hole switch which activates the hole relay (I) - the green highlight
The hole relay has a switch which runs the motor for as long as the hole relay remains closed - the red highlight
The hole eject kicker is activated by a switch on the motor at position 4C closing briefly as the motor turns and through a switch on the hole relay which is closed whilst the relay is activated - the blue highlight
(The hole relay remains engaged through another switch on the hole relay itself until it is released by a normally closed switch on the motor opening - I didn't include all of that part of the circuit for clarity)
Given that the ball in the hole in your machine is running the motor we can assume the first two steps are working OK, so in my example the two areas you would need to look at are
1. The switch on the hole relay (I) which forms part of the circuit to the hole eject coil
2. The motor switch at 4C which forms part of the circuit to the hole eject coil
ie the two elements in the blue highlighted area
In fact on Surf Champ it is even easier, since you can see that the same motor switch feeds both the kickout hole on the playfield and the eject kicker in the outhole, so if the outhole was kicking ok I would know that motor switch was OK (or VV), but I'm not sure that would hold true for your machine
I would start by identifying the hole relay (look which one pulls in when the ball drops in the hole) and checking/cleaning/adjusting the switches on that
If that doesn't solve it you will need to find the motor switch.
Since you don't have the diagram you could try the following
1. There is often a chart stapled near the motor showing what each of the switches do - if that is present that will tell you which is the relevant switch
2. Trace the wires from the hole relay switches to the motor switches - if you have a multimeter with a continuity buzzer you could use this, or failing that look at the wire colours - either way that is going to long winded, hence the usefulness of a schematic!. To help, you can ignore any switches which are normally closed in the dwell position on the motor, and also those at the "impulse" level (ie operated by the jagged teeth) - on surf champ the motor switch is at level C which is the main top cam and easiest to get at
3. You could also ask other owners of the game on
pinballowners.com if they have a schematic they might send you a photo of (or an extract) and also ask the same on
pinside.com - there are a lot of very helpful people on there!
If you need to clean a motor switch remember that the motor can be pivoted 90 degrees by removing a hairpin clip if that makes it easier (assuming a Nordamatic is like a Gottlieb)
Hope that's helpful - it should be a fairly straightforward problem to solve I think
Do post on here when you get it sorted
