Re: how to wire the new two motor gearbox

I have a suspicion.

Spikes come in two flavors. Red and Blue (the labels are diffrent colors). The difference between them, according to IFI's website, is that Blue spikes have reverse polarity protection. That is, wiring 12v+ to the common stud won't kill it. Otherwise, red and blue versions are the same.

Victors come in two flavors. Red and Blue. According to IFI's website, there is no difference, or at least I haven't seen any published note about there being one.

Could it be that blue IFI components are reverse current protected? I'm not ready to test that theory... Just remeber, if you toast a victor, don't blame me!

As for the 'Y' cable, it is legal for competition. I believe some came in the kit, or have in previous years. They seem to always come with a yellow signal wire. While I would recommend using 4 separate outputs, I can't think of a really good reason to. I've always liked the idea of being able to trim each motor independent of the other, but I doubt it's ever necessary. I'm sure theres a really good reason to do it, although I can't think of it. My gut tells me to keep all your PWM outputs separate.

One man, one vote. One motor, one signal. Or something like that.
