Heated Jacket Electrical Question

I have a Gerbing jacket and I have a fairing mounted Gerbing heat controller on one of my bikes. The variable temperature controller powers my BMW accessory socket on the side of the bike where I plug my jacket into. The heat controller use on and off oscillation to lower and raise the temperature on the jacket.

Instead of buying another temp controller for my second bike for $80, I thought I could use a BMW heated grips switch with the high, off, and low settings.

My question is ...
Will the jacket give off low heat with the low setting on the BMW switch?

I'm gettin' the feelin' I'm going to have to test this out myself.

My guess is the BMW Switch has some type of current limiter so the low switch would provide lower heat. Go to a hardware store and buy a cheap rheostat and use that. Seal it up to make it water proof and you should be good to go for a lot less than $80.00. Or rewire Gerbings switch with quick connects so it is easier to move from bike to bike. Or sell second bike and use proceeds to buy cheaper second bike and new Gerbings switch for it.

Won't work, Burnsie. The heated grips switch is a simple SPDT affair, and the hi/lo heat come from built-in resistance in different current paths through the grips.

Thanks David. That's the answer I was looking for.
