STEP 2: LOCATE A GROUND POINT

LOCATING A GROUND POINT

Grounding your wire is crucial to the safety of yourself and your vehicle in the event of a short

circuit. The chassis of your vehicle generally makes a good ground. However, vehicles today are

built with a combination of metals, spot welds, glued together uni-body panels and isolated

chassis components. Therefore, we cannot assume that a good ground will automatically be on

the chassis.

In most vehicles you should be able to locate an obvious ground near the fuse box. Your owner's

manual may even tell you where the factory ground is. If you are unable to locate a ground point,

we'll show you how to locate a ground. There are 2 ways to test your ground point.

TESTING YOUR GROUND POINT

[ SET MULTIMETER TO 200 OHMS

1. Set your multimeter to Continuity Test or 200 ohms.

2. Using the black lead, touch the negative (-) terminal of your vehicle's battery

and then place the
