HELP! - Throttle to Controller connection Question ...

Hi,

I've got a Navitas TSP-100-36 controller and a 0-5k Magura Twist throttle with Blue, Brown & Black wires.

NAVITAS CONTROLLER Connections

The Magura Throttle does not specify what color wires are what (actually no information at all)
For some controllers with two leads, I've read that you just twist the Blue and Brown wires together but I'm not sure with the Navitas Controller, since it has 3 connections. Pot+ , Pot- , Gnd

Any help here would be greatly appreciated.
My guess is:
Blue is Pot+
Brown is Pot-
Black is Gnd
But this is ONLY a guess, I really don't have a clue.

Please Help!

Thanks,

Dave

Re: HELP! - Throttle to Controller connection Question ...

This is one reason why I like resistive throttles - they make sense to me and are easy to figure out with an ohmmeter.

Using an ohmmeter you will find ..

one pair of connectors do not change resistance as you twist the throttles. One of those is POT+ the other is POT-

Another pair of the connectors start at ohm=0 and increase to ohm=5-10k ..

The last pair of conenctors start at ohm=5-10k and decrease to 0

Ok, the Black & the Blue are Pots.
The Brown is obviously the GND.
The Black and the Brown start at 0k increasing to 5k.
So the Black must be the Pot+.
And the Blue must be the Pot-.

Did I pass the deductive (or should I say inductive) reasoning test?

Thanks,
Dave
