Indiana Jones: The Pinball Adventure
Williams, 1993Hi All
I have just managed to get hold of an IJ machine which is in good nick, however the enter, escape and volume buttons on the coin door are not working
I have checked the common wire to the connector on the mpu089 board and the cable is continuous.
Al four buttons are not working
Does anyone have any suggestions?
thanks
Unbelievable. I just ran into this problem on my BSD. I just got the machine to work on and was having difficulties on getting consistent results.
I would push the Enter button and it would work sometimes and not work other times. Then when I finally got the Switch Test to work, the Up and Down button would not work. I finally was convinced that all the buttons were not working at the same time. Something common?
My solution was to check the ground wire (as you already did) and resolder the black wire to the first switch (Enter button). Since all four buttons are out, it has to be the common element (ground). I understand that you metered it all the way back, but perhaps it's not a solid connection?
I also Scotch-Brite(ed) the connectors on the Coin Door Interface board to ensure that the connectors were making a good connection.
Welcome to Pinside. Pinwiki suggests cleaning the dust from the board. Worthwhile to double check the wiring.

Test the board by unplugging J205. Pins 6,7,8,9 on the board are where the test switches are wired to. Ground any of those 4 pins, one test function switch should be registered on each pin just like when you press the test switches. If grounding does nothing your board is fricked up as Lloyd said, probably from the battery leakage. If grounding these pins result in the machine registering the switches, then work back through the wiring back to the coin door interface board, then the switches.

Thanks for that, copied everything you have done and no different result.
Thinking it may be a bit more deep seeded.
Will be trying the rest of the tips too.
Appreciate your help
Quoted from grumppy:Did you check the black wires on the coin switches? It is daisy chained wire from the test buttons and will keep them from working if one is broke off.
Thanks for that suggestion
All seems to be in place and the link is a solid wire securely soldered.
Will keep persevering
Quoted from silver_spinner:does any message come up on the dmd when you press any of those buttons? Example, "close door"?
The DMD appears to work fine showing all the usual messages initially like Williams, high scores and then shows settings factory reset and book keeping cleared

I think you may be on the money
Doing this test did nothing at all
There has been leakage from the batteries previously and this may have caught up with it.
Do you have any recommendations on where to purchase a CPU as I think I will replace the MPU089 board at the same time. Given the processor chips are apparently not that expensive is it worth while doing that one as well given it is a 1993 machine.
I am located in Australia
Really appreciate yours and everyone's help

Borygard sells the Rottendog replacement boards. You generally move the CPU from your old board into the new board.
If you would rather fix the old one Borygard or
ChrisHibler both do excellent work but I think shipping would be prohibitive.

I am in Australia and sell Brand new Original Bally Williams Boards both New or Good Used

You will be able to get the existing board repaired/refurbished back to as new in Australia for less than the cost of buying a new one.
