TEST PREPARATION
CAUTION
Read this document before testing any
snowplows.
•
When connecting the Isolation Module Tester to
the battery, connect the red clip to the
POSITIVE (+) terminal and the black clip to the
NEGATIVE (–) terminal. Connect the black clip
last. When disconnecting, disconnect it first.
•
If an Isolation Module Tester lamp (tester lamps
are white, tester LEDs are green and slightly
smaller) does not come ON, the fault could be an
open lamp element, an open circuit, or both.
•
All vehicle lamps must be operational. An open
lamp may cause false test results.
•
The Isolation Module Tester is protected by a fuse
inside the tester that automatically resets itself. If
the fuse activates, disconnect power from the
Isolation Module Tester and wait several minutes.
Then resume the test.
