I don't know if my question wasn't clear of if I misunderstood the answer.
My charger has a timer board, Ezgo part 603194, which has apparently fried.
I can replace it with the same board which is very expensive, or according to the mechanic, substitute 28667-G01 that is used on older chargers for the existing board.
It looks to me as if the answer says substituting the board is the only way to repair it. Was it meant the using the original board, 603194, is the only way to repair it, or is either way acceptable?
How would the substitute board be wired if acceptable?
