Thanks for all the help so far, one of the last things I did a few months ago was to remove the score reels from position, fully clean off any lubrication I had applied after I found out this was a no no. Cleaned and checked all of the contacts, the day I did this I was convinced I was going to turn it on, start up and play. No dice. That doesn't mean I am not going to do it again this week. So as soon as I have done them all again I will post the resuls.
And to Studley67, no there is no ball in play light, tilt light is off.
I had a thought that possibly everything is working and contacting but maybe a pull in relay is not working, could this be an option?
If so, how do I test each one, do I have to remove the wires? Are they all the same voltage? And what should I use as a power supply?
Sorry in advance if I say something stupid!!!
Thanks again everybody.
