Tusk Grip heater resistor size

anyone have the tusk grip heater kit with the white rectangular resistor...i need to get a new one and need the size off of it

I believe they are 2k ohms. I had those on one of my bikes. high was to hot and low was to cold; so I bought a 1k ohm resistor from Radio Shack and eliminated the 3 position switch to a two position. I basically had a medium heat only.

can't be K ohms unless it is used in a transistorized controller. E=IxR

1000 ohms in series would limit current to less than .oo12 Amps


P=IxE so, .0144 watts max


1K pot on the base of a transistor controller would be OK... I built one for my vest with a 500 ohm in the base circuit

I had one break on me recently. I zip tied it to my fork tube and the stress from the flexing broke a lead off at the resistor. Now I have it hanging in the breeze. I had a 10W 1 ohm resistor I replaced it with. The original was a 2 ohm. You can get them at the rat shack.

I bought a different switch so the grips were in parallel for high and series for low. No need for that vulnerable resistor...

how's the heat in the low position? from what I've read wiring them in series has the grips drawing anywhere from 25 to 50% of the high setting. my bike doesn't have a lot of electrical output so wiring in series should help. do you have any idea how many watts they draw in the low position(series) compared to the high position?......thanks

nice drawing by the way.

JMHO: Spend $4 and turn them into variable heated grips. Best $4 I ever spent:

Now that's what I like about these forums. Good advice!

I think substituting this electronic flasher for the 2-ohm resistor will work well; this flasher only costs $12.99.

I analyzed the DPCO switch cirucuit, with the help of an electrical engineer. The Tusk Heated Grip Kit consumes about 9.0 watts per grip on low setting, with the resistor consuming about 7.2 watts. The high setting consumes about 17.8 watts per grip. Therefore, the low setting generates about 1/2 the heat of the high setting, and wastes 7.2 watts from the resistor.

The DPCO switch circuit consumes about 4.42 watts per grip on the low setting, which is about 1/2 the heat generated by the Tusk setup on low heat, and 1/4 the heat generated by the high setting. Therefore, I think I am going to install an electronic relay in place of the resistor. The LED dimmer is very nice, and inexpensive; however, it's just too large for me.

This device is tiny and will handle 144 watts.

http://www.ebay.co.uk/itm/Slim-3-Key...item27c55e0488

its about 1/2" wide x 2" long and 1/4" thick and remembers the last setting after power off, so can be used in place of the resistor and fine tuned to give the desired heat setting. Or velcro onto the dash for fiddling about on the move.

You can get 20A flasher relays for $2.49 from China on Fleabay:
