Checklist Preview

  • Battery: identify battery type and rated CCA/Ah
  • Battery: inspect terminals, case swelling and electrolyte if serviceable
  • Battery: measure resting voltage after surface charge settles
  • Battery: load test according to battery rating
  • Battery: measure voltage during cranking
  • Battery: inspect ground strap and positive cable condition
  • Battery: check parasitic draw if battery repeatedly dies
  • Battery: confirm charger mode matches battery chemistry
  • Battery: record pass/fail before replacing other parts
  • Battery: reset clock/adaptations as needed after battery work

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.
