VOLTAGE DROP TEST
The Voltage Drop Test is used to test for bad
connections. When performing the test, you are testing
the amount of voltage drop through the connection. A
poor or corroded connection will appear as a high
voltage reading. Voltage shown on the meter when
testing connections should not exceed .1 VDC per
connection or component.
To perform the test, place the meter on DC volts and
place the meter leads across the connection to be tested.
Refer to the voltage drop tests in the "Starter System
Testing Flow Chart".
Voltage should not exceed .1 DC volts per connection

3. Loosen the hose clamp (A) and remove the coolant
hose from the thermostat cover (B).
4. Using an 8mm socket, remove the (2) bolts that
retain the thermostat cover (B) to the engine.
