Checklist Preview
- Voltage drop: test circuit while it is loaded
- Voltage drop: place meter across the suspected cable or connector
- Voltage drop: measure battery positive to device positive
- Voltage drop: measure device ground to battery negative
- Voltage drop: wiggle harness only after baseline reading
- Voltage drop: inspect heated or green connectors
- Voltage drop: repair one high-resistance point at a time
- Voltage drop: repeat test after repair
- Voltage drop: record before and after voltage drop
- Voltage drop: avoid replacing modules before power and ground are proven
How To Use It
Use this checklist before replacing parts. Work from the top down, record the result of each step, and only move to repair decisions when the failed test is clear.
The downloadable PDF includes checkboxes, notes space, final verification and technician sign-off fields for workshop records.

SEO and Research Notes
This original Motomech worksheet is built from common workshop inspection logic: verify the complaint, inspect safety-critical systems first, measure before replacing parts, document the failed test, and finish with a repeatable road-test or service verification.
