out on a limb here.....
harleys switch the "ground" on their bikes
savage switches the hot....
you can reinvent the wheel but will it be better? round works.on the savage more ground points work...
remindes me of my electrican days was giving a fellow worker a ride home and he told me how when he was doing dishes at nite he get a "tingle" at the sink...
when we pulled up to his abode i saw the situation..
he was renting an old(lucy and rickey)type trailer with the axle removed and up on blocks.there was some zip(lamp) cord coming out of a hole drilled by the front door to a jelly jar porch light...
who ever wired this modern convenience didnt take into consideration
they were dealing with 110v ac not 12 volts dc and used one of the sheet metal screws holding the aluminum skin to the trailer as a point for the "ground"....which is not "ground" at all its the grounded conductor in ac circuits..SOOOOO the whole metal fabric and any other metal(plumbing pipes) had 110 volts (less the resistance of the 60 watt bulb)potential when the porch lite was on..
i unscrewed the bulb and told him to find a new place to live..
id leave the harness as designed..but thats just me
