To
check the heating
resistance
of
a rear
window
measure
1. Either the current
flowing
in the resistance,
using an ammeter connected in series
to
the supply lead of
the element.
The current
should
be
Saloons

to
10,6
amps

voits
Estates
8.5 to 9.8 amps at 12 valts

Or the resistance
using
an
ohmmeter.
Resistance should be

Slide the
twa
pointed
probes of the
warning
lamp support on
the cut wire.
When the lamp
lights
up,
the
pointed probes are
on both
sides
of
the
break in
the
wire.
By
slightly
moving the
probes along
the length
of
the wire,
the exact
extent of the
cut
can
be
determined
