Symptoms & Testing
- Common failure symptoms
- • No crank, only a click
- • Slow crank
- • Dash lights dim while cranking
- • Needs a jump repeatedly
- How to test it
- 1. Measure resting voltage at the posts with a multimeter after the truck has sat.
- 2. Load test the battery, or have it tested at a parts counter.
- 3. Check for voltage drop across each cable and terminal while cranking.
Symptoms narrow the list of possibilities. They never confirm a diagnosis on their own — test before replacing anything.
