cutout stuck in the closed
position, defective switches which do not break the circuits when in
the open position, or grounds or short-circuits in the cables and
wires connected to the battery.
If the voltmeter pointer does not move from the "0" line on the scale,
complete the battery connections by fastening the positive battery
cable to the positive battery terminal, and make the test described in
Section 2. If the voltmeter pointer moves from the "0" line, and gives
a reading equal to the battery voltage, connect the voltmeter
permanently between the positive battery cable and the positive
battery terminal and make a general inspection of the wiring, looking
for cut or torn insulation which allows a wire or cable to come in
contact with the frame of the car, or with some other wire or cable,
thereby causing a ground or short-circuit. Old, oil-soaked insulation
on wires and cables will often cause such trouble. If a general
inspection does not reveal the cause of the current leakage, proceed
as follows:
Closed Cutout, or Defective Cutout Windings. (a) If the cutout is
mounted outside the generator, remove the cover from it and see if the
points are stuck together. If they are, separate them and see if the
voltmeter pointer returns to the "0" line. If it does, you have found
the trouble. The points should be made smooth with 00 sandpaper. See
that the moving arm of the cutout moves freely and that the spring
which tends to hold the arm in the open position is not weak or broken.
If the voltmeter pointer does not return to the "0" line when the
cutout points are separated, or if the points were not found to be
stuck together, disconnect from the cutout the wire which goes to the
ammeter or battery. If this causes the voltmeter pointer to return to
the "0" line, the cutout is defective and a new one should be
installed, unless the trouble can be found by inspection and repaired.
If the voltmeter pointer does not return to the "0" line when the
battery or ammeter wire is disconnected from the cutout, see paragraph
(d).
(b) If the cutout is mounted inside the generator, disconnect from the
generator the wire which goes to the ammeter or indicator. If this
causes the voltmeter pointer to return to the "0" line, the cutout
points are stuck together or the cutout is defective, and the
generator should be taken apart for inspection. If this does not cause
the voltmeter pointer to return to the "0" line, replace the
