New Jungle Lord project. According to the limited documentation I have, this sounds like it is booting in Diagnostic mode.
I have cycled it several times, but the same thing occurs:
When I power the machine player 1 display shows 2503 1
credit digits displays 4
match digits cycle through numbers 0 to 50
Sometimes is screeching from the sound board, but inconsistent
I have GI, then the attract lights flash and restarts the cycle when #50 is reached
I get 0's using the test buttons on the CPU
Before changing the batteries the error was 2503 4 - this was referenced in the instruction booklet and cycled several times to clear it
I cleaned and re-seated all the connectors on the cpu & driver board
I did not touch the 40-pin yet
The coin door test buttons seem a little flaky, but the cycle occurs even if I disconnect the door harness
CPU/Driver & sound boards are in decent shape, power boards was hacked a little
Are there any next steps before I send off the boards to get reworked?
