JT07067 Test Harness
The purpose of tests are to check continuity in
miscellaneous circuits and wiring harnesses when a volt
meter is not available.
IMPORTANT: Turn key switch off before
disconnecting any electrical
connectors. Disconnecting electrical
connectors while engine is running or
with key switch on can damage engine
and pump controller or other electrical
components.
Retainer tab on male half of wiring
harness connector halves must be
pushed down before pulling halves
apart. Never pull on wiring leads.
1. Test harness may be used as a probe light. Indicator
light (E) comes ON when connector (A) contacts 24
volts while eyelet (C) or bullet connector (D) is
grounded.

2. Test harness may also be connected in series with
components using bullet connectors (A and D). When
circuit is energized, indicator light (E) comes ON.
NOTE: Indicator light will not come ON if test harness is
connected to the ground side of a component.
3. Energize circuit being tested.
4. Observe indicator light (E). If light come ON, the fuses,
wiring harness, and switches to accessory have
continuity to the battery.
