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 4-10. Connect DVOM (Part No. H-D-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 proce-
dure. 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.
