| Ground connections on the bike are like a spider web - they should all be interconnected through the various ground bolts, harness connectors and individual components. There should only be a very slight difference in resistance between any two ground points in the entire system. If there is excess resistance between any ground point and the negative battery terminal, there is something loose, frayed, corroded or disconnected. | Ground connections on the bike are like a spider web - they should all be interconnected through the various ground bolts, harness connectors and individual components.

| - | Over the years, HD has grounded the Sportster electrical systems in a number of ways. In the early models (typically, 1993-earlier), **components were grounded to the frame** at a nearby point while power was distributed throughout the system on a minimal number of wires in the wiring harness. There could be as many as a dozen points on the frame used for grounding. The front lights & instruments were grounded thru a connecting strap between the forks & the frame. | + | Over the years, HD has grounded the Sportster electrical systems in a number of ways. |

| **Beginning in 1994**, the wiring harness itself began to carry ground wires to various components. The wiring harness by then consisted of many separate power wires to multiple locations, with a number of circuit breakers protecting the various circuits from overload. | **Beginning in 1994**, the wiring harness itself began to carry ground wires to various components.
