Battery seems to be draining regularly since HD installed driving lights to a friends sportster. Aside from a nest of wires that they shoved into the side covers it looks pretty clean. There's a 15 amp fuse feeding a relay w/ a small switch mounted on the bars. When replacing his battery there as a draw and noise coming from the speedo (and the speed indicator lever bounced a couple of times). The lighting wires do feed up to the speedometer but what would be drawing power as the key was off?
