Recently got a Road Kings with severe battery corrosion. I ended up getting an Alley Cat system 11 board and trying to convert it to Road Kings. I am getting no numbers on the CPU LED. Game is on my bench and just hooked up the power connector at 1J17. Here's what I have done so far:
Checked all voltages to ROMS, RAMs, and PIAs.
1. Added missing components (K1 relay, resistors, and transistors)
2. Replaced U26 and verified the other 3 ROMs.
3. Replaced RAM at U25.
4. Reset and clock are both good on U15.
What else can I check and does anyone know what the jumpers should be? I checked with my old board and some of the jumpers are different.
Pictures are of the old and new CPU.
