HOT GRIPS 203 (HW - Hidden Wire) - Manual (Page 3)

The ceramic-resistor may be remotely mounted from the switch, using any length wires you
need. Mount it securely on a metal area where there will be air moving around the resistor to
dissipate heat. It will warm up during "low heat" operation. It is not in use during "off" or "high".
The resistor should be secured preferably with plastic wire-ties. Squeezing out a "pad" of sili-
cone sealant under the resistor is helpful in cushioning it against vibration and shock. Resistor
may be located any distance from the switch. Use black wire left over from the grip's installa-
tion to connect and do not leave the resistor dangling by the wires or they'll fail.
WIRING: There is no polarity to the wires on each grip, i.e. no positive or negative. Follow the
wiring illustration next page. A good ground is important so be sure to scrape the paint off the
"ground connection" as even a layer of paint will create a problem. Ground should be to the
engine or frame, not the handlebars, since some of them are rubber mounted and may reduce
the good ground connection. Some machines use a wire or "common-wire ground" instead of
"frame-ground". Check with your snowmobile dealer. The grips must be wired in "series", with
one grip being connected to the other. One grip's remaining wire connects to ground, and the
other to the switch.
SKI-DOO: Some Ski-Doo snowmobiles don't use a "chassis-ground" for the grips. Instead, lo-
cate a yellow wire and a yellow with black-stripe wire at the sled's Regulator or Regulator-Rec-
tifier. Use the yellow wire as your power positive wire, and the yellow with black-stripe as your
'ground-substitute' wire. Do not ground to chassis or engine except on older Ski-Doo's that do not
have the yellow and yellow with black-stripe wires. Improper wiring will result in the Hot Grips®
not working and/or dim lights. If in doubt contact your Ski-Doo dealer's service manager.
Power Source: Use the vehicle's accessory terminal if available, one that will not
have voltage when the engine is off. (Otherwise your battery will be drained if the
grips were left on, just as if you left your headlight on.) If your electrical system us-
es fuses for protection, then use a 3 or 4 amp fuse. On non-battery systems, gen-
erally if they don't use fuses in the system for other electrical uses, then a fuse isn't
necessary for the Hot Grips®. Some sled's do not have enough electrical power to
run both the headlights and heated grips. Ask your dealer's service department if
in doubt. In such a rare case, you would have to turn off the headlight during day-
