    Hi,

    I bought two 12V wiper motors. I've stripped the electronics inside, but it seems they have seperated motor windings - there are three collectors which are connected to the inner rotor. They are marked with 2,3 and 6.

    Collector 2 is ground (it was connected to the motor body). But where to connect 12V+? To collector 3 or 6? Or to shorten 3+6?

    Hi,
    Is that 3 and 6 not used for the slow and fast speed ?
    if you use a 12V power supply with limited current (let say 0.5 amps) there is no risk to try connecting pin 3 and 6 to +12Volt and pin 2 to ground. According to size of wire inside the rotor, there is no risk to have it burnt.
    You'll have to try it, not much we can do remoteley.
    Cheers

    Thanks. I've an adjustable power supply at work. I'll give it a try.

    The motors dont have a connection/pin for slow/fast speed. There are three pins: Pin1=12V, pin2=ground and when pin3 is set to low (ground) the motor starts rotating. These pins are soldered to a pretty big SMD board.
