(4) Connect the heavy negative external shunt

to the negative post of the grounded battery and the

negative lead of the voltmeter with the selector on

t h e 50-volt scale.

(5). Connect positive ( + ) voltmeter lead to the

b a t t e r y plug terminal.

( 6 ) Close the starter motor switch (with the

i g n i t i o n switch in the OFF position) and read the

(7) Starter motor amperage should not exceed

300 amperes, maximum.

(8) Voltage should read not less than 18 volts.

(9) If the starter circuit conforms to the above

tests, remove the test leads and connect the ground

cable to the negative post of the grounded battery.

( 1 0 ) If the starter circuit does not meet the

above requirements, check the circuit using the
