Dynamite17:

Here's where I measured on my 07 FXDC and the readings I got. All reading were taken 3 different times each and with the fork in 3 different positions: full lock left, full lock right and straight on. I did the straight on to see if there was any difference by having the forks at the stops, providing another potential ground path.

1)Frontbrake banjo bolt toforward control mounting bracket bolt,A/C bracket head bolt, primary cover bolt: All reading 0 ohms +/- .3 ohms

2)Triple tree headlight bolt to forward control mounting bracket bolt, A/C bracket head bolt, primary cover bolt: All reading 0 ohms +/- .2 ohms

3)Triple tree upper clamp bolt to forward control mounting bracket bolt, A/C bracket head bolt, primary cover bolt: All reading 0 ohms +/- .2 ohms

4) Handlebar riser cover bolt to forward control mounting bracket bolt, A/C bracket head bolt, primary cover bolt: All reading 0 ohms +/- .2 ohms

All these reading are within normal grounding specifications for a 12V DC system and within tolerance of the Fluke digital multimeter I was using to take the readings.

As previously stated by others, the wire is certainly there to provide a more positive ground path, but based on the readings I just took, I see no issue, but the call is yours.
