Thanks for that Trev (and especially for the schematics etc)....I was going to brave the cold and start looking for shorts!

the thing that threw me was that I am sure at one stage (before I re-did all the molex connectors on the PSU) was the bumpers used to flicker in unison with the flippers....so obviously that was a fault which Ive now fixed

Grand total of stuff done (not too bad for my first machine I spose)

All electrolytics changed
Remote Battery added
7406 TTL Inverter changed
LM-380 Audio amp changed
new rubbers and stuff
re-pinned PSU
about 8 lamp driver SCR's changed
two TIP-122 solenoid drivers changed
1 pop bumper coil re-wound by hand (never again!)


In that case its all finished....when I get sick of it I will let you know, I have no particular think for Hankins, it was simply forsale in the area which saved me an 8 hour return trip to Melb or Canberra to buy something else
