Under the playfield is the bonus unit. This is the first area to check. I take it you are not hearing a coil firing 15 times quickly after each ball. It is supposed to count through all of the 15 targets after each ball and give bonus for those that are lit. There are leaf switches on the bonus unit that tell the game when it has completed the count. Check all of the switches on that unit and also make sure both coils have no broken wires etc.
Yes, I don't hear the 15 count...I just hear a bzzzzt. Sound. I have some time tomorrow so I will check all of these things.
Ok, great news the bonus is counting now.The "G" relay looked good but closed one switch a hair tighter and bingo.....but it's slow, not like a machine gun but more chugga, chugga... going to clean up the solinoids and links to see if that helps.
Ok, getting close.... bonus works good but slow...now if I hold the "G" relay in I'm getting that wonderful machine gun sound....love it!!!.... does the "R" relay hold it in???
Sorry my computer is down...so I'm only on my phone...hard to read the schematic.... phone is cracked too lol.
Checked the DX, seems ok. By bonus unit... Do you mean the one for the fifteen count on the stepper itself?
Ok ,I checked them they seem ok.....when the bonus is counting down, the G relay is clicking on and off. It all works correctly, just slow because is not staying down the whole time???
I'll check those next, my silly job is interfering with my pinball obsession....will report back...and thanks again .
Hi
I use currieddog snippet of schematics - along "green lines" the "Initial-Current" flows - the G-Relay pulls-in - closes its Self-Hold-Switch (, lets the motor run) --- along "red lines" the "Self-Hold-Circuitry" is established ((( - motor-1C then opens and cut "green lines" - no problem as "red lines" functions***))) --- when all is done: The "15th. Pos. Bonus-Unit" Switch cuts "red lines" - end of feature.
Your "red lines do not function*** - maybe a switch, maybe a Jones-Plug in the connection - maybe a wire in the connection (?)
. Greetings Rolf
Yes working slowly, I worked in all the Jones plugs when I first got the machine. It's probably why it started for me , when the seller said it didn't start.
Ok , I went over this circuit and checked everything. Everything was good but the N/C switch on the bonus was open....I adjusted and verified it's closed and open on the 15 count. Now it doesn't score bonus and doesn't kick the ball out.
