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
“Starting System
Testing Flow Chart” page 4.16 .
Voltage should not exceed .1 DC volts per connection
