Robbe motors versus engine sound modules
I have both a robbe unit and a caldercraft unit, both are unable to "sense" off the robbe navy motor.
both sound modules have a pair of wires which pickup of one motor, one wire of the pos/neg terminals of the motor supply, both Ive tried connecting directly to the motor. Ive even swapped the wires over, just in case there was a polarity difference.
Ive spoken to caldercraft [jhn] and he does seem to remember s there is a problem with the way the robbe motors are "wound" internally, plus they use a capacitor within the motor case or something, please appreciate my Ignorance on this, as Ive not removed the motors from their position in the boat, as it was purchased secondhand, with original motors in situ so to speak. they both work, so didnt see the need to remove or replace. [or even just take out just to be nosy!].
Best wishes.
