Voltage drop in a circuit
|
|
1.
|
Connect a voltmeter across:
|
|
|
•
|
the positive battery terminal and terminal 30 on the
starter motor;
|
|
|
•
|
the positive battery terminal and terminal 50 on the starter motor
(voltage in the starting position only);
|
|
|
•
|
the negative battery terminal and the starter motor casing.
Start the engine and read off the voltmeter. The
reading obtained should not exceed 0.2-0.3 V.
|
|
2.
|
If a circuit shows a higher reading it should be checked to
determine the reason for the excessive voltage drop.
