Thanks Derek

I tested all the solonoids and they all seem to read about the same resistance. They all look to be OK but I will go back and give the plungers a wiggle as you mentioned and see if anything obvious is up.
I killed my good multi meter a while back when I was measuring the test points on the rectifier board. I'm back to using my old DSE bar graph multi meter which works but is a little hard to read.
I think my DSE multi meter shouold be able to test the transitors, will check that out. I gotta get a new meter but thats another thing.
I'm planning on rebuilding the HV section of the board, not sure if this machine is a keeper but it certainly is giving me some good knowledge and experience.
As for the pop bumpers, they seemed to be working but only just, I'm not sure if this is possible with the playfield fuse out so maybe I was just imagining it.
Oh, how do I test the transistors?? can this be done on the board??

Cheers
