- | ====== EVO 1-3 Socket Checkpoints ====== | ||
- | With a EVO 1-3 ECU, when removing the EPROM it's entirely possible to damage a track on the top of the board and still allow the engine to run, but cause a number of malfunctions. | ||
- | |||
- | If the engine runs, it indicates that the connections between the processor (IC1) and the EPROM are okay. | ||

- | Check for continuity of the tracks to the EPROM as follows: | ||
- | |||
- | ^ EPROM ^ IC2 ^ IC1 ^Notes ^ | ||
