Monte Carlo Ramp Issues!

[Mike Walsh]

Hey Folks, when my "Monte Carlo" pin is off the ramp is in the down position and when the pin is turned on it goes to the up position. I have tried everything I can think of in game play to get it to work with no success. The coil is warm/hot after I play so I'm guessing it's not supposed to be this way. I have cut and checked the diode
It is good. I am new at this and I can't seem to locate the transistor thru the schematics as a possible suspect. If anyone knows which board and area to check that would be a great help. Just as a foot note the three prong coil and the switch
set up do not match the ones in the manual. This manual did not come with the machine I got got it on line. I will attach some pictures for reference.
It all looks good just not the same as the manual. Maybe a production change at the manufacturer?

The pictures!

Did the ground mods. Took care of two smaller issues ie: speaker static and occasional display not working.
Found some info on pinside regarding suspect transistor under play field. I did some testing and this may be the problem. I am waiting on a replacement transistor . Will post how it all goes.

Update, located,tested and replaced the transistor located close to the ball trough all alone.
Odd I thought! Anyway ramp is working! My first tech repair!!!!
A few pictures of the culprit in case anyone else has the same issue.
Note, replaced transistor #2N5884
as a substitute for original transistor #2N5879.

Holy! That IS an odd place for the transistor
Looks like a short hazard too.

Good thing you didn't burn up the coil. You got lucky.

Nice fix!

Thanks Drano,
Working on a bank of drop targets not working out of the blue! I think it may be on the driver board.
As I read somewhere " system 80 it's an adventure". No kidding!

Or as a Menace likes to say "system 80... 79 more problems than system 1"
