Diagnosing the Issue

Finding the source of an electrical issue takes patience and diligence. Here is a step-by-step approach:

1. Take Note of Symptoms

Pay attention to when and how the gremlin appears. Does it only act up when wet outside? Has it started since you installed an aftermarket accessory? Making note of symptoms will help you pinpoint the cause.

2. Inspect Wiring Connections

Look for any damaged or unsecured wiring connectors. Wiggle them to check for looseness. Examine wires for damage. Tighten and repair any suspect connections.

3. Check the Battery and Alternator

Use a voltmeter to test battery charge and alternator output. Weak battery/charging can allow gremlins to strike.

4. Look for Corrosion

Inspect battery posts, ground straps and electrical connectors for any visible corrosion. This can cause resistance and wreak havoc. Clean any corrosion you find.

5. Consider an Automotive Computer Scan

If gremlins persist, have the onboard computers scanned at an auto parts store or shop. Diagnostic trouble codes can reveal issues.
