Hi bonzo71
in Your "collection" I see You once owned a Nip-It --- in the beginning of post-29 You say "Bonus-Unit does NOT step down one position at a time" - in the end You then just say "Bonus Unit resets". From Your post-29 and the schematics (see the JPG) I clue: In Nip-It the Bonus-Unit is a "Total-Reset-Stepper" - when "reset" is triggered / activated: Wroam, bang - in ONE huge step all the way down to "Reset-Position is Zero-Position". Is my writing true ? Greetings Rolf

Hi PinballGurus
I take "switches / switchstack on Bonus-Unit" - see the first JPG - on the right is a picture from Your video in post-34. I visited http://www.planetarypinball.com/mm5/merchant.mvc?Screen=BOOK - Bally-1976-Parts-Catalog http://www.planetarypinball.com/reference/partsmanuals/BLY_Parts_1976/index.html#/96/zoomed - made a snapshot, then had to turn the snapshot 180 degrees - then pasted the snapshot into the first JPG (on the left) --- two switches are actuated by a nylon-rod mounted on the gear.
See the second JPG - "encircled blue, CC": The End-of-Stroke-Switch on the Bonus-Unit to cut Self-Hold-Current on Advance-Bonus-Relay, "encircled blue, BB and DD" - the two mentioned switches actuated by the nylon-rod on the cam - "BB" has a connecting wire red-yellow to a solder-lug on the Bonus-Unit-Step-Up-Coil - I see this wire in the first JPG (on the right) - BUT, question - wire-red-yellow soldered-on to what blade - B-1 or B-2 or B-3 or B-4 ?
Second JPG, "encircled orange, AA" we see that the schematics is drawn not having current in the pin --- "encircled orange, BB": At start-up when the Ball-Index-Relay is not yet pulling: Current can flow through switch on Ball-Index-Relay making the Bonus-Unit to step-up from Position-Zero to Position-1 - when the turning motor actuates motor-switch-10A.
Second JPG, "encircled orange, EE" we see the Bonus-Unit after stepping up from Zero to 1.

The questions are - Your video (post-34), my first JPG here, on the right: Is Your Bonus-Unit in "fully resetted (means Position-Zero) Position" --- or is the unit stepped-up to Position-1 ?
When You start a new game - does the Bonus-Unit fully reset - then step-up one step ?

When You do testing "Ball rolls in Eject-Hole - Points shall be given": Park Your finger in the Eject-Hole (simulating "Ball lays in the Eject-Hole) - park Your finger in the Eject-Hole until the Kicker kicks Your finger - then take the finger out.

(((I always fear schematics on pins having the feature "every new ball starts with 'Bonus-Unit has been stepped up from Position-Zero to Position-1' " --- is the drawing in the schematics "Position-1" or Position-Zero ? - a mix of "here in the schematics Pos-Zero" but "here in the schematics Pos-1"))) Greetings Rolf
