After a seemingly successful playfield swap I had the upper right flipper on my NGG smoking and burn its label a bit, and after some research I figured something may have failed at its transistors.
Using pinwiki I read the following:
>A quick check of the TIP-102s on the driver board can save time. Set your DMM to "continuity check". Place the black lead of your DMM on board ground. Touch >the tab of each TIP-102. If the meter indicates continuity, then that TIP-102 is shorted. This quick test works only with TIP-102s and with TIP-36c transistors >since the tab of a TIP-36c is NOT connected to ground.
Using this information I checked and it seems like all of my 36c's are shorting when measured to the ground braid. The pin out on the data sheet shows the middle leg being the collector, and in the schematic the middle leg goes to ground.
I have a new 36c here and the old one out of the board and I cant find a whole lot of difference testing them against each other.
I figure I should replace all the transistors associated with the aforementioned smoking flipper, so as not to potentially damage my new coil, but am I wrong in thinking the wiki meant to say:
>This quick test works only with TIP-102s and >NOT< with TIP-36c transistors
Or where am I going wrong in my thinking here? Any guidance would be appreciated.
