I'm not going to get into the standard bits about installing a
HeatTroller on a bike you can read about that
elsewhere. Instead, I'm
going to talk about the things you need to be aware of for my particular
installation or, as it were, things I wish I knew when I did mine, so
you can be aware of the issues.
To install the switch/LED in this location, you'll need to trim down the
circuit board they're mounted to. This means removing the strain relieve
on the wiring so be sure to add some strain relief downstream. I used a
zip-tie with a large "head" that goes just inside where the wiring will
exit the housing. As a bonus for a stock looking installation, the hole
that the factory wiring bundle comes out through is large enough for the
HeatTroller's wiring as well, so you won't need to expand the existing
cutout or add a new one. Of course, you'll want to take the back half of
the housing and HT to your workbench, get it set up and holes drilled,
then take it to the bike and route the wiring before installing the HT
under the bodywork...
Be aware that you'll need to plan the routing of the wiring bundle to
avoid the turn signal switch one time when I put it back together I
wasn't careful and the turnsignal switch wouldn't work. Run the wires
all the way to the side of the housing (away from the grip) and you
should be fine. (Just be sure to plan that routing when you set your
I centered the switch in the right side of the housing. This meant I had
to do a little trimming on the inside of the housing it'd be easier to
move the switch further to the rider's right...
I was trying to arrange the switch/LED so that the LED was directly in
front of the switch. To do this, you can see the switch is rotated a
bit forward. While it's still possible to reach it and adjust it with a
finger w/o taking your hand off the bar, it's not as visually appealing
as if it would be if it were more "vertical". Next time, I'm going to
separate the LED from the switch (the circuit board is scored so that
you can break it apart for this purpose) and mount them separately.
LEDs are "linear" light sources most of the light goes out along the
axis*. Since the LED in my installation is pointing away from the rider,
it's hard to see if it's on (or how much it's on) in daylight without
holding my hand over it meanwhile, I'm not watching the road...
Because of the location of the housing in relation to the left grip and
clutch lever, it's much easier to take off the grip, do this install
first, then install your heating elements, and re-install the grips.
It's not impossible to do it the other way 'round, but getting the
housing on/off when you have to work around the extra wiring etc. is
There are still 2-3 one-button gizmos I want to put in the switchgear
housings one for a PTT switch, one for a cruise control*, one for a
garage door opener. But those will have to wait for the '04, unless I
get bored. ;-)
* After some discussion with a couple people off-list, I think a cruise
control on a bike can have the majority of desired functionality reduced
to one button "set/coast". If the CC is hard-wired to turn on when the
bike does, and disconnects when you squeeze the brake/clutch, then the
only thing I'd really want to be able to do is "set" it if I want to
speed up, I'll do that manually, then press "set" again. But that'll be
August or so...
