Quoted from gambit3113:
After mine stayed on long enough for me to figure out what was happening, that transistor was so hot that the board smelled like it was on fire. It would melt thru that board pretty quick.
I like our All Gambit, All the Time thread we have ourselves here, too.
To keep this "gambit only" shaker story thread alive a while longer I will tell my shaker motor story. One of my first pin repairs on my first machine. I was super new to the hobby.
It was an Earthshaker, and the shaker motor stopped working. I did some research and people suggested the motor brushes, and that a certain car part number was a replacement. So I ordered that, and the parts were not identical after all.
So then I found some identical replacements online and the shaker motor worked! For 1/2 of a game.
I found this confusing; but decided to try and replace the transistor next. With the crappy tools I had on hand at the time (and my low level skills) just doing that simple thing was "hard". But I got it done! I plugged everything back in and the shaker motor worked.... for a game or so.
I then ordered a whole new shaker motor, installed it, and.... it worked for a game or two.
I finally went into the backbox, found the connector that runs to the shaker motor, and it was very obviously burned up. So I replaced that, and the header PINs. I don't think I had ever done that before either.
All told, this took the span of ~2 years. In between waiting for parts and giving up on before coming back to it.
And I learned an important lesson: It is always a connector issue, except in the rare times it isn't . Anyways I learned to start with the "mechanical" stuff even when it seems to be an electrical problem. Doh!
