WIGGLE TEST 4.7
GENERAL
NOTE
DIGITAL TECHNICIAN (Part No. HD-44750) can be used to
perform wiggle test.
The wiggle test checks for the presence of intermittents in a
wiring harness.
PROCEDURE
1. See Figure 4-11. Connect DVOM (Part No. HD-39978) to
wiring harness between the suspect connections. When
diagnosing ECM connections, a BREAKOUT BOX (Part
No. HD-42682) may be used to simplify the procedure.
See 4.6 BREAKOUT BOX.
2. Set DVOM to read voltage changes.
3. Start motorcycle engine and run at idle.
4. Shake or wiggle harness to detect intermittents. If inter-
mittents are present, radical voltage changes will register
on the DVOM.
