I put the contactor on the cycle today.
I installed the forklift "ignition" key where the cycle originally would have had its key.
This connects the 36V battery pack to the contactor coils, which then snaps shut the the contactor, powering up the system.
Definately sexier having an electro-mechanical device on the cycle instead of just a big dumb switch.
Officially, Alltrax's documentation says you are supposed to have both a diode and a resistor in the mix too. Apparently when the magnetic field on a contactor collapses, it can send high voltage backwards, which can cause problems with the controller. The diode stops that from happening. The resistor is supposed to help prevent arcing at the contactor. I didn't see any arcing, so I don't think that's as big a deal.
Besides, I still have 3 more forklift contactors kicking around anyhow!
I picked up up a diode at Radio Shack, and will throw that on tomorow.
Perhaps I will make a YouTube video showing the contactor in action?
