STARTER CURRENT DRAW TEST

NOTES
Engine temperature should be stable and at room temper-
ature.
Battery should be fully charged.
See Figure 1-11. Check starter current draw with an induction
ammeter before disconnecting battery. Proceed as follows:
1. Verify that transmission is in neutral. Disconnect spark
plug wires from spark plug terminals.
2. Clamp induction ammeter over positive battery cable next
to starter.
3. With ignition switch ON, turn engine over by pressing
starter switch while reading the ammeter. Disregard initial
high current reading which is normal when engine is first
turned over.
a. Typical starter current draw will range from 140 to
180 amperes.
b. If starter current draw exceeds 180 amperes, the
problem may be in the starter or starter drive. Remove
starter for further tests. See the
STARTER ON BENCH, Free Running Current Draw
Test.
NOTE
A DC current probe may be used if an induction ammeter is
not available.
