Check for a dead battery, then check
for an open resister or open wires
from battery to alternator, or a short-
ed wire between the alternator and
control panel switch and alternator
and battery.
TROUBLE SHOOTING Electric Wand & Hose
No heat, or low heat in wand
or hose.
With engine OFF,
Check for loose pulleys and
loose or missing belts on
24 volt alternator.
Start engine, with wand
switch OFF check voltage at
battery terminal of 24 volt
alternator.
With engine running, turn
wand switch ON, check volt-
age at battery terminal of 24
volt alternator.
Check heating elements for
an "open" condition. Check
for faulty switch. Check for
broken wires or loose con-
nections from alternator to
switch, and switch to heating
elements.
Repair or replace alternator.
Check for "short" between switch and heating
elements. Alternately disconnect the wires to
the hose and wand heating elements, when the
voltage goes to 24 - 28 volts you have located
the "shorted" circuit.
Check element resistance as follows:
15' hose element: .4 to 1.0 W.
20' hose element: .5 to 1.2 W.
Wand element: .9 to 1.6 W.
Repair or replace as necessary.
