Credit Wheel won't Advance

Archived from groups: rec.games.pinball (More info?)

I just picked up a '75 Gottlieb Abra ca Dabra. When playing the game
you can hear the 'knocker' when you score a free game (via points or
sequence awards) and it seems to be trying to advance the scoring
wheel, but the wheel never goes higher than "1" credit.

It will go back to zero credits when you start the next game but just
won't advance past one credit. This game has the "speedometer" type
credit wheel with the two solenoids and white ratchet wheels.

Don't know if there is an easy fix for this.

Thanks.

Take the unit apart, clean it, replace any bad parts, lube it lightly,
reassemble. Does that sound easy? It is for me, not sure for you.

Given the OP's description, it sounds a lot more like a problem with
one of the switches on the credit wheel assembly. I'd recommend
checking all the gaps, and also: check to be sure the post on the wheel
isn't forcing the AddCredit switch open at the 1-credit position. It's
possible some previous owner moved this post from a more reasonable
location (like 9 or 15 games). If you're not familiar w/ EMs, this is
a short post, or pin, mounted perpendicular to the disk. As the number
of credits increases, this post moves towards one of the switch stacks.
When the post gets there, it forces the switches open, defeating the
"add credit" circuit. I'm embarrassed to admit I can't remember if
the "knocker" circuit goes thru this switch stack as well -- if it does
then clearly the stack is closed, although the AddCredit switch might be
bent or dirty.
