The switch itself is new and the diode if good. I pulled the plugs from 1J10 and 1J8 from the CPU and put a test light on pin 7 and pin 2 respectively. (these are the wires that go to the right lane change switch) Closed the switch and have continuity.
I just got my CPU back from being repaired (for a different issue) and was assured everything tested as working 100%
Everything else on the game works as it should.
Am I missing something? Is there anything else I should be looking at?
