I followed the closed loop or "series" set up in the directions, including a resister for the Low Temp setting. It heats up great! Other than forgetting to turn it off and draining the batt., Is it bad to run the power line with a 5amp in-line fuse directly to the battery and ground to the frame?

I'mnot sure which Ignition controlled power line would be suitableto tap into for this accessory. I was considering on tapping into one of the rear marker lights in case of an electrical melt down. Any advice would be greatly appreciated.
(I'm not up on resisters and such)

If you have small enough hands, you could tap into you tail light hot wire at the fuse block. That will give you your key on power (thats what I did to run the relay for my secondary fuse block)

 

I think that the headlight wiring is the only one that's heavy duty enough to handle the power without using a relay. If you run a realay, than anything that's live with the ignition on should work. The relay only takes a tiny bit of power to turn on, then all the juice is directly from the battery. A relay is probally the best way to go and you can get one with all the wiring needed for less than $20 from any auto parts store. They're usually sold next to the fog lights.

 

Connecting the ground side of the grips to the frame is OK as well as using a direct connection to the battery plus terminalvia a 5 ampfuse. The fuse should be located near the battery though since the wire between the battery and the fuse is unprotected. An in-line fuse about 10 cm from the battery terminal is a good solution.

If you want to secure not to drain the battery and don’t want to put in extra relays, you can connect the heated grips to the headlight low beam wire,if you normally drive with headlight on, or at least when you want warm hands. In Sweden we must use the headlight all the time and it is good to do so anyway since you will be seen well by cars. I guess the rear lights are not relay driven so a connection to the rear light could burn the light switch and even the ignition switch if that is included in the circuitry to rear lights.

Just check in the wiring diagram that your model year is provided with a headlight relay, but it should be. The CBR 1000 F wiring diagram I looked into included head light relays and I guess they are the same. In case the headlight fuse is 20 amp, you can use a 25 amp fuse instead, it will still protect the wires if a shortening occur.

 

Run a relay. Or tell me what brand of battery you use and I'll by stock in that company.
BTW I tapped the tail light for switched power for the relay that controls the fuse box that my grips are connected to. The front headlight is on a relay, but it designed for the headlights and not to have another accessory tapped downstream of it. I think it's only a 15 amp. Not 100% sure though.

 

Thanks for the info guys, think I'll work a relay into the mix...
