I had a defender that worked perfect. It had the old battery pack on the cpu board. I did the bob roberts lithium battery mod on the board. When I put it back in, the machine booted up into test mode. It says to press advance to do settings. I hit all buttons behind the control door with no response. I checked switches, and they are ok. It was on freeplay when I got it, and I never checked the test mode. Now that I changed the batterys, I lost the settings in memory, and I can't get out of a default test mode screen. Any ideas? Worked perfect before the battery conversion.
