Setup
1. Connect the red power cable from the LeakMaster
to a 12V DC power supply. If you are using a battery,
verify it is in good condition and fully charged. See
Figure 1.
2. Connect the black ground cable from the
LeakMaster to the vehicle's chassis ground.
CAUTION: To prevent
personal injury, do NOT connect
LeakMaster's black cable to a
battery ground, because a spark
in the vicinity of the battery can
cause an explosion.
3. Depending on the tests you are performing, connect
either a nitrogen or shop air supply line to the water
separator located on the back of the tester. See
Figure 2. Supply pressure must be between 50 psi
and 125 psi.
When testing EVAP systems: Connect the
nitrogen line to the water separator.
When testing systems other than EVAP:
Connect the air supply line to the water separator.
Remember, all tests performed with
the LeakMaster are performed with the
vehicle engine OFF.
