wire and
see paragraph (d).

(c) If no cutout is used and connections between the generator (or
motor-generator) and the battery are made by closing the ignition or
starting switch, such as is the case on Delco and Dyneto
motor-generators, and some Delco generators, disconnect from the
generator or motorgenerator the wire that goes to the ammeter or
indicator. If this causes the voltmeter pointer to return to the "0"
line, the switch which connects the generator or motor-generator to
the ammeter or indicator is defective. If the voltmeter pointer does
not return to the "0" line, replace the wire and consult paragraph (d).

(d) Defective Starting Switch. Disconnect from the starting switch the
cable that goes to the battery. If one or more smaller wires are
connected to the same terminal as the heavy cable, disconnect them
also and hold their bare ends on the bare end of the heavy cable. If
this causes the voltmeter pointer to return to the "0" line, the
starting switch is defective. If the voltmeter pointer does not return
to the "0" line, replace the cable and wires on the starting switch
terminal and proceed as follows:

Defective Switches. See that the ignition and lighting switches are in
their "OFF" positions. If they are not, open them and see if the
voltmeter pointer returns to the "0" line. If it does, you have found
the trouble. If it does not, disconnect from the switch (or switches,
if there are separate lighting and ignition switches), the feed wire
which supplies current to the switch from the battery. If this causes
the voltmeter pointer to return to the "0" line, the switches are
defective. If the pointer does not return to the "0" line, replace the
wires on the switch and consult the next paragraph.

If there are other switches which control a spot light, or special
circuits, such as tonneau lamps, or accessories, such as gasoline
vaporizers, electric primers, etc., make the same tests on these
switches. If no trouble has been found, see paragraph (e).

(e) Grounds or Short-Circuits in Wiring. Disconnect from each terminal
point in the wiring system the wires which are connected together at
that point. Also remove fuses from the fuse blocks. If the voltmeter
pointer returns to the "0" line when a certain wire or fuse is
removed, there is a ground or short-circuit in the wire or in the
circuit to which the fuse is connected.

(f) Turn on the Lights. Remove the voltmeter and complete the battery
