Fire Escape (Mech-Tronic) Expert help needed (please)
Hi,
Picked up a Fire Escape (Mech-Tronic) and was sold as "working" (no funny business, I had agreed to the condition) and it did play for a bit.
The voltage was low (+4.82vdc) but there is no voltage adjustment on the PCB, (AFAIK) so I eventually swapped out the LM7805 and replaced the filter cap. Voltage is now great at +5.02vdc but other issues have materialized.
The most troubling is that a ball no longer discharges from the top as it should. As I do not have any real operation manuals, I am learning as I go and it appears that there should be more balls. The reasoning behind this theory is that I can see a ball just below the eject level on the left side top chute as I crank the eject lever clockwise, if there was one more ball on the stack, it would come out.
Whats very strange is that it was working and then just stopped, so where did the ball go!?!?!??!
I checked everywhere that I could and have not located it.
Also the chute solenoid is not energizing although there is power going to it when it is supposed to, checked with a DMM, so that needs to be replaced as well.
Here's what I got so far, from observations and guesstimates, you credit the game, the game goes through the start up theatrics, the ball "barrier" at the bottom of the game opens via the activation of the solenoid and allows the ball to go into the stack, thereby allowing a ball from the top to be discharged as the handle is cranked? This cycle is repeated until all balls (as paid for) have been exhausted and then the Game Over and High Score lamps cycle?
Can anyone please shed some light onto this for me as I have no operations manual and would like to get this going again.
BTW, how does one add a ball, (if this is necessary), is there a secret method or do I need to disassemble the mechanism, it does not look like fun......
Thanks in advance
Jeff
