Re: [DML] Now idle motor problem (was idle problem)

["stainlessilusion" <5n-@xxxxxxx>]

What else can it be? I've disassembled one of those motors so I know
how they work or how their driven. I just purchased an NOS motor that
when I apply 12 volts and quickly touch a terminal with negative-it
closes/opens depending on the side so I know it works fine. But still
when I connect it-nothing happens and the motor stays silent. I've
already gone over the wires and switch, only thing that's left is the
ECU. As far as the wires, every single one is positive, and it doesn't
change back and forth between negatives-so with no negative at all
present I thought well how will the motor operate. How much is it to
ship to Germany? I may be able to ship it very cheep to Holland and
then from Holland to Germany-might save if from US to Germany is
pricey. This ECU has had some previous work-just a capacitor was
changed.....-----Dani B. #5003
