If that's the case you can measure it. Voltage is put on CN7, then goes through the lamps, and via CN6 it is switched to ground if the light should be lit.

First measure, because there can also be a loose wire in a connector. You can measure voltage and compare the values with the working lamps.

If your schematic is of a poor quality, have you tried downloading it from ipdb?

[marty]

I just take the file IPDB.
it is better, I'll print it tomorrow because on a screen that was not easy to read.
I'll test values.
thank you

Do that! Unless you're chicken!

Unless you're chicken!

That would be another Data East top pinball machine....
PS: Ah, I see. Why JP, isn't BTTF a better one for you?

[marty]

the jurassic park is very good.
Data East the rules are simple and fun to play is immediate.

BTTF is just for nostalgie.

I had a simmilar problem where a lot of lamps wheren't working on my JP. it was one of the diode's that was stuck open on mine.I can look things up for you i have the manual here, but your description of wich lamps aren't burning is very bad can you make a better description of the one's that are not lighting up?
