pincoder .. received my Adaptor the other day. Thanks, it's great.
Trying to get my 
Firepower working again. I was getting intermittent issues of games stopping and GI going out, typical things I've seen on the forums. Decided to finally break down and bulletproof according to 
vid1900 guide. All new interconnect, new sockets, new trifurcon connectors instead of the IDT, NVRAM module and special solenoid saver boards from 
barakandl . When I finally got it all back together the diags told me I had a ROM/PROM error. I thought I had a solder bridge or bad trace or something, but checked and rechecked all the sockets, tested continuity on ALL the lines and everything looked good. Popped in the Pincoder adaptor to see if I could narrow things down. Got to the switch tests (06-switches) and discovered EVERYTHING in the special switches/solenoids to be non-responsive, so.... left and right slings, all pop bumpers, right flipper advance. I have tested continuity from the board connectors to each device and they are good (just in case I screwed up the wiring in the connectors).
I assume the Pincoder adaptor CAN test the special switchers, right?
Not sure where to go next. I tried sticking a DMM on the board end of the left sling, both on the switch matrix and on the special switch, then closing by hand but see nothing. I'm assuming there is more to testing these switches than that? I put the DMM to the coils and measured 34.5 VDC so it isn't a power issue.
