Working on Getaway HSII.
The start button works and will start a game. The light does not work. Bulb or led bulb is good. Checked with meter and get a pulsing about .5 volts when credits are on the game. If it worked the light would flash. Not great with a meter. Put new connector on power driver board end. Does not work with OEM power driver board or new Rotten Dog driver board. Have tried several start buttons all the same result. Only thing left I can think of is the WPC coin door interface board. Does not look like there is much to it. Do not see any for sale or they are out of stock. Looks like they cost about $30.00 so probably not worth sending for repair. Everything else works and the wires are attached where they are supposed to be looking at the manual. Not the end of the world if the light does not work but curious why it does not? Do not have another coin door interface board to try.
Thanks for the help.

I put the meter on the lamp socket and got the .5 volt pulse. Lamp socket is in the start button and have tried several start buttons new and used. ?

Yes all the other lights test and work correctly. Yes coin door interface board has a diode for start button lamp. Perhaps something to do with getting like .5 volt pulse instead of enough to light lamp.

Tried swaping the wires to the socket. Borrowed another coin door interface board that is known working and thats not it. Verfied several times that the wires are connected to the correct places. Changed the connector on the driver board. Thought continuity was good because I get the .5 volt pulse. Not able to get to this machine again until next weekend. Will read about using a digital meter but of the 2 meters I have one is 40 + years old gauge type and the other is digital but a harbor freight 5 dollar special. Thinking when I have time and can order more connectors of replacing both the wires.
Thank You

Wow Thank You. Printed the diagram. Please jump in. Hope we all can figure out. Tried several bulbs and a led button bulb. Tried several start buttons old and new. They all work to start a game if there are credits. Replaced the connector at J 138. Waiting for more connectors and some time to get to the game. Could try new

wires.

Figured it out for this HSII. There are 2 Red-Grey wires going to J-133, J-135 # 9. One on a single connector and one on the populated connector. Both were on the fully populated connector with one being in the 4th place next to the key. Moved that one to # 9 on a connector by itself. That got the start button bulb to work. There are also 2 Yellow- Blue wires that need to be the same. One to populated connector at J- 138 #6 and another to a connector by itself at J-137 # 6. I Think the connector positions that are the same with the same keys are inter-changeable.
Thank You all.
