Inertia Drive Starting Circuit Test Procedure
REV. 07/21/2008
Before Starting:
Battery voltage should be tested and must be at 12.4 VDC or
higher. Do not proceed if battery voltage is less than 12.4
VDC as battery should be charged.
Test meter leads before use. (Set meter to Ohm’s and check
for resistance reading of less than 0.10 Ohm)
If available, use clamping meter leads to assist with testing.
Set meter to next highest voltage scale that includes 20 VDC.
When taking readings, allow the meter to stabilize before
recording. The reading should stabilize after 3 to 5 seconds.
If reading continues to drop while cranking, stop the test
and perform a battery load test.

Inspect For Corrosion at Terminal Connections:
Use a wire brush to clean the surfaces of the connections.
Inspect All Crimped Connections:
Tighten loose crimps or replace the connectors.
