I will start this post with the "I know, I know" statement. Pennant fever is that annoying System 8 game to stay away from. That being said. I bought one.... I know nothing about pinball machines but I am an EE with 20 years of communications electronics behind me so I thought, why the heck not... turns out to be a really fun project and I love the fact that everything is traceable and repairable, like the good old days. And this was absolutely my favorite game as a kid!!!
So
I have re-capped and replaced a bad Zenor on the power supply. and now have the game functioning at about 80%.
Next in line:
Lighting issues:
this will all be solved by replacing the molex connectors on the power supply, voltages are all good to go.
Q: what molex do I use here? and how is the best way to source them, has anyone found a bulk kit they like (i have the tools all ready)
Magnet coil:
This does not work. The relay is firing but no magnet. I have not dug into this yet..
Bat Coil and rheostat (or lack there of):
he bat works fine but it has been hacked. I will include a pic later. It appears the rheostat that controled the bat power burned up (it was fixed by removing the entire assembly and placing a sticker over the burn that reads "engineering" haha)
Q: I want to restore the bat to stock with the rheostat assembly in line. Does anyone have information on parts or wiring for this? Or even better, have the bat adjustment assembly as a spare part for sale?
Coin lock out:
The coin system does not work. In the coil test, nothing happens for the coin lockout (#4 SM-35-4000-DC) so I assume this is the issue...
Q: is there a good tutorial on basic coin door operations and repair? I assume they are all basically the same, I have zero experience and could use some basic education....
we will see what comes next after all of this.... Probably LED conversion... but I want to get it back to 100% before doing any of that..
Thanks,
John
