Grip Heaters & Ohms Law

[Red2003]

The trouble is a 1 ohm resistor capable of that kind of watts will be the size of a d cell battery. Not gonna be easy to "hide" one of those in your handlebars. The RX1 warmers are 2 ohm, so replacing the Apex grips with those would help, but kinda defeats the purpose of those cool new grips. I would definaately NOT wire the stock grips in parallel. ECU's are too costly for that, and if you smoke one out on the trail, your done for.

FWIW,

I just received some Moose ATV hot grips for my Grizzly monsters. While I haven't checked them out for heat output, the specs list the wattage at 19W and 38W @ 13.5 Volts respectively for the Low and High settings using a series/parrallel switch.

They also add the caution that older ATV's may not provide sufficient wattage to operate the headlight and heated grips at the same time. This is likely why we see the higher resistance value on the 98 SRX as that machine did not produce the total wattage of today's machines.

According to the math, the wattage is there, something else must be stealing the heat. :itchy:

I talked to my dealer today and was told it would be no problem putting the RX1 05 grips on but would loose the hook and could not put 06 hook in them. Looking at about 1 hour labor and price of grips if it has to be a last resort fix.. Would be better than freezing your hands but I,m sure Yamaha will repair it under warrinty.Also UNKOWN are the Grips the problem ?

Gut feeling

It goes against my better judgement to purchase a new model change in the 1st year. I am getting that I should have waited for the 2007 instead of purchasing this year feeling. I HATE BEING A TEST RIDER/ Owner. I can hear the all the drama starting already. You paid 11,000 for a sled and the hand warmers dont work..

could it be that the aluminum in the grab handels acting like a heatsink? Just a question

If every one looked at it that way you would nevev be able to get a different sled becauce no one would buy the first year. Its going to be fixed so lets give Yamaha a chance.

I have taken a hard look @ this hotgrip issue for a couple of days now and here is my conclusion.

1. The actual Hotgrip appears shorter in length than the old YAMAHA stock grips.

2.When I place my hands on the bars in a natural riding position My pinky finger and maybe 25% of my ring finger are off the hotgrip and on the straight part of the hooked end.

I honestly think I am just going to have to adapt to the problem because I just don't see them having a new grip design allready on the shelf to fix the problem. From what some guys have posted on TY the power seems to be there for the grip. But 20-30% of our hands are not in contact with it. JMO. We are supposed to get 6-12 inches of lake effect tonight and if we do I will hit the old Railroad grade and run some 6000-8000 RPM steady throttle testing to try to confirm this.

I've been kind of lurking in the back ground on this thread but I have a couple of thoughts. I have hand warmers on my ATV and there is no way they are as warm as a sled. Reasons well for one there is no wind protection and I think the voltage output for the grip circuit is un reguleted off of the stater on a snowmobile without a battery. So at higher RPM we could see higher voltage to the grips.

On a 4 stroke I would bet the power to the grips comes off the battery, thus 13.8 volts. If we have different resistance grips we would have more heat for sure but something will smoke for sure unless there is a relay and fuse to isolate them from the system. Parrall wiring would work but you had better have an isolation relay and larger wire.

A person would be amaised at how much heat is removed by the cold air moveing over the grips. I wonder if wind protection is more of the answer than anything?

On a lighter note, remember the days of the old Phazers with no hand warmers we didn't even know there was a problem with cold untill we installed hand and thumb warmers.

Good luck, I'm sure Yamaha will fix.

I actually wired my grips on my SXR in parallel and it did make them warmer. The down side is the head light was very dim and if you put the brake on it took even more power from the sled. At idle it almost stalled. There must be a better idea for heating your hands. Doug

I put a taller windshield on my attak on my second ride. It did not seem to help. Same temp as the first ride. Left the setting on high all day. Usually after 20 minutes I am turning them down. NOT on this sled.

Re: Gut feeling

Thanks for pointing that out. I did decide to purchase this years sled. I just hate that Yamaha is aware of the problem and ships all these defective units to the dealer w/ no fix.
This is what R&D is suposed to fix.Last year.Remember as we are getting our 06 THE 07 are already being made. How else can you see the newest product in Feb. in Canada etc.

I am not going to debate this issue any longer. It's B.S. I rather put up w/ paint peeling off the HOOD (really). Not a creature comfort like a hand warmer. If this trend was a Ski doo issue.
We would be all over them.

Many years I added hooks to my bars & always had less heat at the grips than my buddies sleds had!

I believe you loose heat because of the extra unheated area robbing it!!!

maybe yamaha wants to sell Hand Gaurds.

LOL

I can't really understand that because Cat and DOO and Ploaris for that matter have bean doing it for years and there handwarmers are not the greatest, but they still worked better than what we got.

Yes, but a Phazer did not cost 11,000 bucks either..... Yamaha, better fix this......
