anyone worked with a 4100 hydro? can’t get the motor to crank with the key, jumping the starter only makes the engine turn over, no fire.
we’ve checked the safeties: pto switch, seat switch, neutral switch etc. I’m leaning towards the a2 control module, the rubber boot has some signs of overheating on the inside but all the pins, wires don’t look smoked. i imagine this part is not cheap but will have to wait til monday to check price.
