If I install heated grips on an '82 gl500, will the electrical system handle it? Will the headlight dim if I turn on the grips? Anyone have experience with this or knowledge about this bike's electrical systems ability to handle added load? I appreciate your help, Thanks, Paul

The GL500 and GL650 bikes can easily handle that extra load with no problem.

bpcorliss, How much did they help, and how much more comfortable did it make the cold riding? Larry

Yes, they made an amazing difference. The biggest thing first though is to get wind protection. The hottest grips in the world won't help if you are losing heat over the top of your hands. If your bike doesn't have a fairing, get a windshield and "hand protectors". I have seen people put dirtbike deflectors on thier street bike. Also, National Motorcycle products (makers of National Windshields) make deflectors that I used to have on my Valkyrie.
Here is a link to what I am talking about: http://www.nationalcycle.com/catalogue/CoolWeather.shtml
For the HotGrips, I actually have to turn them down when I have them on unless it is really cold. Yesterday it was -6C (20F) and I had to turn them down because my hands were roasting. It isn't until it is around -12C (10F) that I can leave them on full for any length of time. I also wear Military Arctic Mittens (not gloves) to keep warmth.
To see some advice on cold weather gear, check out this link: http://choppercharles.com/cs/forums/66845/ShowPost.aspx
In it, I list all the stuff I use and either examples or the web-site you can buy similar.
Good luck on the install!

Thanks Bob, I like those better. How long do they take to heat up a set of grips?

So you drill a hole near the bottom of the handlebars and feed the wires through there? How warm do the grips actually get. I can see the left one doing a good job as it's flush to bare metal but with the twist grip on the right does it warm up as good as needed?

I have mine wired to a DPDT centre off switch so that when the switch is up the heaters are in parallel (36W) and when the switch is down they are in series (9W). I have a light next to the switch that is connected across the left heater so that (at least in theory) the right one will get a little more power when they are in series.
I also have my reflective handlebar muffs and wear snowmobile mitts when it's cold out.
How hot? Well, here's how my usual drive to work is: If it is -20c and I switch them to high on my driveway I start to feel the warmth after less than 5 Km of mostly 80 Km/h or faster driving. This is a couple of Km before the next town. If I don't switch them to low as soon as I feel the warmth they will begin to become uncomfortably warm before I get to speed up on the other side of town (distance from home about 8 or 9 Km). Sooner if I have to stop for the crosswalk. My hands are warm enough for the rest of the (mostly 80+ Km/h) trip with the heaters on low, but I usually switch them off a couple of Km before I arive and they are still warm after I park and get the block heater plugged in and mylunch out of the topbox.
At temps above -10 I usually leave the heaters on low unless I decide to wear gloves instead of mitts.
BTW: The reflective muffs make a big difference. I had to go to Beaverton (about 16 Km at mostly 80+) for some errands on Friday. It was just around 0c (freezing for those who live in backward countries ;-) when I left so I just wore my gloves and didn't turn the heaters on. I took the gloves off at my first stop and left them off while I drove around town at 50 Km/h, then decided to see how cold my hands were on the less than a minute run down the highway to the next stop and ended up coming home bare handed inside the muffs.
I should also mention that at temps approaching -25c I often leave the heaters on high for most of the trip to work.
It does take a tiny bit longer for the heat to get through the twistgrip, but, as far as I can tell, 5 minutes into the trip my palms are equally warm. My right hand (& arm & leg &c) always feels a bit cooler than the left when it's cold out, but that's mostly because of the wind that runs up over the nose of the sidecar and onto my right side. It always seems to find it's way between the gauntlet of the love and the sleeve of the jacket, not powerfully enough that there is danger of frostbite, but enough to be annoying.

"If I install heated grips on an '82 gl500, will the electrical system
handle it? Will the headlight dim if I turn on the grips? Anyone have
experience with this or knowledge about this bike's electrical systems
ability to handle added load? "
I just got through installing heated grips from Cycle Gear on my GL500 and it handles them just fine. Voltage at cruise was 14.2 before I installed them and seems to run at 14.4 volts with the heaters on. With a combination of Hippo Hands you can easily ride down the interstate with the ambient air down in the 20s.
I mounted the rheostat on the left handlebar and ran the wiring harness under the gas tank to the switched accessory 12 volt supply hiding under the seat. The main wiring harness's ground point is right there and makes a fine place to tie in the grips ground as well. This also gives you something to do with all the wire supplied with the grips.
The only problem I had with the installation was the heated grip was too big on the throttle sleeve and had to be built up a little to avoid throttle slippage. I used a couple of small pieces of that thin rubberized material they sell to line toolbox drawers. No glue needed, so nothing gets gummy when it gets hot.
I don't ride with anything else heated but since the installation, I've noticed other parts of my body cooling down for the first time. It was always my hands before. I ride in cold weather with a heavy sweatshirt covered by a leather jacket, thermal underwear, jeans with leather chaps, boots, and a full helmet. Now in really cold weather I wear gauntlet gloves; otherwise I wear mesh gloves. The Hippo Hands gives you some latitude.
http://www.hippohands.com/HHSmallWM.htm http://www.cyclegear.com/spgm.cfm?L1=&L2=&L3=&L4=&item=PRC_A99-00010
It only takes a couple of minutes before you become aware of the heat being generated. Unless it's absolutely frozen outside, you'll end up having to reduce the heat after a while. Although I suppose the left grip might take a bit longer to heat up since it has to warm up the handlebar directly first, in practice it down't seem noticable. Both hands seem equally comfortable. Frankly, this is what I should have done when the weather first turned cool. It makes riding possible on days where there are no other riders.

Oh, hell. I'm retired now but I was a PADI Master Instructor teaching in Charlotte, NC. Haven't been diving since 1992.... developed other interests but I still have the gear.

When I got my first set of Poly Heaters they came with an SPDT centre off switch and a resistor and instructions to connect the heaters in parallel and wire the switch so that thwhen the switch was in one position the heaters were fed directly and in teh other position they were fed through the resistor.
Being an electronics tech and knowing that I was going to run extra lighting &c I decided that the resistor was a bad idea - why waste watts that could be charging the battery just to heat a resistor. I sat down with a pencil & paper for acouple of minutes and figured out how to switch tehm from parallel to series with a DPDT and have been doing it that way since.
Poly now has dual heat units with 3 wires. Much easier to wire up.
BTW: One of my best friends from high school was a qualified diving instructor. He became a bike mechanic too.

Hi Paul.... and that's one more diver aboard! I recently put heated grips on an '82 'B' I'm no electrical genius, but the guys here on the U K site guided me through and it's a breeze... and well worth it! System doesn't even notice it. One good tip was to power them from the rear brake light feed under the seat, as this is 'off' when ignition is off in order they can't be left on and flatten the battery
Here's to warm fingers!
Loz.

Not the best place to connect them. That 10A circuit has the turn signals, brake lights & horns. The turn signals flashing and the brakelights each draw just under 2A per bulb. The horns I'm not sure about, but anywhere between 1.5A & 3A per horn seems typical. I don't know what kind of heaters you have, but Poly Heaters draw 3A on high.
You must absolutely never honk your horn while the brakes and/or signals are on while you are using the heaters.
You would be much better off to connect them to the instruments circuit. It has only the 7V regulator (temp gauge) and the oil & neutral lights. I'm not sure off hand if the connection inside the headlight (brown/black wires) has a second place to plug something in, but if it doesn't you could always use a Scotchlock. Finding the power inside the headlight is also preferred because the wires will be shorter and you won't have to run them through the frame unprotected.
If you really insist on connecting them under the seat, the tail light circuit would be better than the brake light circuit. All that's on the tail light circuit is the tail lights (about 0.25A each) and the lights in the speedo & tach (total about 1A). There's also an unused connection to this circuit inside the headlight shell (brown wire). The drawbacks are: - If you don't wire it carefully and blow the fuse you won't have tail lights. - If you use the "Park" function on the keyswitch to leave the tail lights on the heaters will also be on.
But, as I said before, the accessory connections are still the best place to connect them if your bike is so equipped.
