ok... is that the full model# or should it be ECG25?
anyway a 02 code is saying forward ws selected on key on and 03 is reverse was selected at key on. will need to test wires at tb2 and tb5 (forward) and tb2 and tb6 (reverse) for shorts and and to made sure they are getting proper voltages when selected. could have a bad selector or a bad card.
