RESULTS: 1.) Ammeter indicates discharge or
no output............................................................................Go to Test 43
2.) Ammeter indicates a charge..................................................Discontinue tests
Disconnect Ammeter from circuit and reconnect Wire
#66
to Terminal
Strip before proceeding.
TEST 43 -
CIRCUIT BREAKER
A.) Disconnect Wires #77 and #78
from the Circuit Breaker. . Set VOM
to ”+DC” and to "Rxl*' scale, and
zero the meter. Connect meter
test probes to Circuit Breaker
terminal studs. Meter needle should
swing upscale to "zero".

TEST 44 -
DIODES D1 & D2
A.) Disconnect Wire #78 at the
battery charge circuit breaker.
Set VOM to "+DC" and to "Rxl"
scale, then zero the meter.
Connect the Positive (+) »test
probe to Wire #78 from Diode D2.
Connect the COMMON (-) test
probe to Ground. Meter, needle
should not move. Set meter to
"-DC" (or reverse the test prob­
es). Meter needle should swing
upscale to some raid-scale read­
ing (approximately 7 - 1.2. Ohms).
