So I fired up my TZ and started to play. I think the slot kickout worked once and then stopped. Went into solenoid test mode and it definitely does not fire. All other solenoids are working properly. Diagnostic says it's white-brown and white-yellow pair.
Doesn't appear to be any blown fuses. I really didn't have the time to start doing disassembly and testing yesterday, but would someone please confirm that what I want to do is:
1. de-solder one wire from solenoid coil and measure resistance across coil (what should the resistance be if the coil is not shorted or open?) Obviously shorted coil is going to show near zero ohm DC resistance and would have probably taken out a fuse right? I'm guessing (since I don't have a schematic handy) that there is one fuse that would cover not just the slot kickout solenoid but others as well.
Presuming the coil is good, that would make me believe that it'd have to be the switching transistor Anyone give me a clue which one it is? Would I be able to measure the transistor while in circuit (eg., across B-E, E-C, C-B and figure out if it went?
