1. Starter

NOTE:
When measuring voltage, wind a piece of tin foil
around the tip of the tester probe and press the foil
against the wire with your finger.

4) When tester indicates 12 volts when its probe
reaches point ªAº, a broken circuit occurs between
point ªAº and the negative terminal. Slowly move
tester probe toward the negative terminal while
contacting it on heat wire to locate point where
tester indication changes abruptly (0 volts). This is
the point where a broken circuit occurs.
When tester indicates 0 volts when its probe
reaches point ªAº, a broken circuit occurs between
point ªAº and the positive terminal. Locate a point
where tester indication changes abruptly (12 volts)
while slowly moving tester probe toward the posi-
tive terminal.

C: REPAIR
1) Clean broken wire and its surrounding area.2) Cut off slit on (used) thin film by 0.5 mm (0.020
in) width and 10 mm (0.39 in) length.
3) Place the slit on glass along the broken wire,
and deposit conductive silver composition
(DUPONT No. 4817) on the broken portion.
