Boy, well 2 steps forward ...one step back....the game is now playing, ball kicking out everything working ok. Except now it's not adding players after player one. Instead when you hit the reset button it just resets player one.

The issue with adding players would be related to the coin unit. Check the switches that send power to the "add coin unit" coil. I believe these switches would be at the U relay, the S relay and score motor switch 1D. Make sure these switches are clean and adjusted properly..
For adding 10 points during start up, there might be a playfield scoring switch that is adjusted too closely. Or the 10 point relay switches might need adjustment.
No lights in the backbox is usually a Jones plug issues. Disconnect the Jones plugs in the backbox and make sure they are clean. Re-seat the Jones plugs...
You may have done something in the score motor on the last problem. It looks like 1B might cover both problems; DX is your first ball relay. Or you may have done something on 2B; "P" is the Add Player unit. Also, look at the Replay Button relay circuit, right above the circled Start relay.
K thanks again, I will check as soon as I can. Also the back box light fuse blew again..so there's probably a short there, it blew right at the end of a turn...was ok during play. Although I put a 10 amp I'm it as I didn't have a fifteen.
Quoted from Metropolis:it's not adding players after player one. Instead when you hit the reset button it just resets player one.
Quoted from Metropolis:One strange thing is when you hit reset it adds 10 points to player 1 and then resets player one.
A stuck playfield switch would cause both of those problems.
So I'm going over all the drop target switches, they seem to be adjusted right...but now I'm getting a repeating chime and it's constantly adding ten points.
So I had a look at the bumpers, adjusted them...looked ok but I put the meter on them for continuety and it beeped as they were all closed?

They can seem closed when they're not because of continuity elsewhere. To use a meter you have to unsolder one side of the switch.
I cut up an old credit card and put a piece between each switch leaf and the steel stopper..I did that as it was adding "tens" one at a time... through all nine switches. No luck?
Quoted from Metropolis:No luck?
I understand "No luck?" to mean that you didn't find anything out from that test and you're wondering what to do next.
- You can try unplugging the playfield Jones plugs and see if that helps.
- If that localizes the problem to the playfield, the next easiest thing is to look closely at each switch.
There are other things to try but best to start with the easiest.
Yes I blocked all the contacts, I tried blocking them all ( the bumpers)... thinking maybe two were closed...no luck there...I unplugged the play field. It stopped..so it must be a switch. I guess I'll try to unsolder each one at a time and check with a meter.
Checked the 10 point relay "N"....player 1 add tens switch is in the player unit stepper in the back box?
Quoted from Metropolis:I guess I'll try to unsolder each one at a time and check with a meter.
You might first unsolder the 10 point wire from the Jones plug just to make sure.
Ok I found it! It was one of the back drop target switches....but now it resets the score reels but the score motor keeps running.
Quoted from Metropolis:it resets the score reels but the score motor keeps running.
These switches run the motor. Is the Start relay (S) staying energized?
That's really weird because those targets score 300 on hit and then the 1000 bonus when the ball drains.
Quoted from Metropolis:the s relay isn't staying energized.
Then check the switches that run the motor.
