All relays perform
some kind of electrical switching function.
I use this type of relay
for operating my handlebar switches, starter, headlights - Hi beam to Low
Beams - horn button, turn signals, etc. The illustration below shows
one of my fuse/relay panels
Got an email from a guy
who wants to use this relay to activate the clutch in an auto stick
tranny. You need to send a ground to the tranny from the handle
bar switch. So here is the diagram as I understand it.
