Heated gear?

A buddy who no longer rides gave me a bunch of his gear. Included was a heated jacket liner from Gerbing. Has anyone had any issue with the electrical system adding components? I also have a SpeedoHealer, power commander, both of which have to draw really low amounts. I’d also like to install a gear indicator. Anyone have info on the available power from a stock electrical system? Thanks!

your heated vest will likely use about the same as your high beam. all the other devices you have mentioned don't use any appreciable amount of power and need not be considered.


so if you're worried about it, don't use your heated vest and high beam at the same time

Ultimately, the answer above was close enough to be reliable. However, I really wanted to know for sure and so it made me do some more research. My initial question was hoping that someone had already figured some of this and I wouldn't have to start from scratch. Here's what I found - hopefully this info will be of some use to anyone else who might need it.

Alternator output is rated at 329 watts @ 5,000 rpms. Obviously, you're looking at a little lower output at idle in traffic/stop lights/etc...

If you run both hi and lo beams, brake lights and turn signal at the same time, with the few other electrical components I can measure, you're looking at a draw of just under 190 watts. Things like the instrument display, fan motors, fuel injection, etc. I can't find specs on. They've got to be small by themselves but they also add up all together.

My Gerbing jacket liner is rated at 83 watts. This pushes total usage up around 270 watts. Gloves would obviously add more (20-30 watts).

I'm going ahead with the install of the harness for the jacket liner. I'll include the list of individual specs below for anyone who cares to keep reading. For the SP2 specific ratings, SP1 is slightly less.

Headlights
Lo - 55w
Hi - 55w

Brake lights - 23w x 2 (SP2)

Tail lights - 8w x 2 (SP2)

Turn signal - 23w

License light - 8w

Depends on the manufacturer. I’ve found them between 40 and 60 watts/pair.
