I am not quite sure of what you want to do and why? The purpose of a relay is to provide low current control of a higher current draw item. I don't have the exact current loads for each of your items such as the starter (which does have a separate cable for it's very high current draw) the starter s...

Despite the inside of the headlight shell sometimes looking like a bundle of jumping snakes, unless the PO, spliced on wire to existing factory wires, everything is pretty well sorted, All the stock wiring is pretty well color coded, Solid color wire is usually a hot unstitched or uncontrolled, unfu...

I hear tons of stories and there are numerous battery threads on batteries saying all kinds of things pro and con, with everyone having a favorite brand. As I said, my local shop has replaced /5 batteries with sealed and as far as I know has never had a problem. The biggest shop problem with batteri...

You know I haven't asked a simple question and the answer might shed some light how to proceed. The relay you have on hand, does it have the internal wiring diagram stamped on the case or printed? If it does, can you take a good picture and attach it so we can look at it? I am asking for the reason ...

If you like cleaning terminals and corrosion from your battery mounts as well as checking fluid levels go for a traditional battery. I don't have a /5 myself but the shop I frequent who restores and repairs installs more sealed batteries than traditional. I can say that since I switched to sealed Od...

Kurt, that is the same schematic as the color one I provided. LOL, The problem is, there are two vastly different systems between the single horn /6 and the dual horn /7. The single horn system had the horn as "hot" all the time via the green black wire and to operate it was grounded via t...

The diagram you have shows a "hot" switch, the factory version is shown in the bottom diagram I posted. In this case there are two separate wiring routes, one for the switch with a hot and ground and one for the horns with a hot and ground. The confusion is the horn diagram you have shows ...

Could the lower prices be due to more bikes coming up for auction or sale now that older owners or their families are selling? I don't see many guys under the age of 60 at my friend's airhead shop and sadly each spring brings drop outs who are selling out, thinning out or just died. Since I don't go...

I didn't draw the unused connector, my switch also has five connections. St.

Not quite sure if this will help, it is a quick diagram of the wires on the back of the ignition switch I made. St,
