Yep, that makes sense. Thanks!If you check the old boush Relays Harley used in the 80's had different amp ratings I believe with the same pin configuration.
Could be why there are different Part numbers different Amp rating for different circuit's
Starter relays are higher Amp rating usually
You only need to have the starter relay. It will work for both circuits . :thumbsupI believe some have switched the starter and ignition relays around on newer sportsters in an emergency situation (mine is a '05 1200C). But is there any difference in the two other than a part number? Is it really necessary to carry both in our tool bags?
