Junction Box what for?
So My bike does not have a splash guard I am about to make one out of diamond plate.
But this junction thing that has 12 volts on both sides was just hanging by a zip tie on one of the splash guard mounting tabs.
I can see a small bracket coming off the starter that was probably what held it in place but its broken. Something else to fix
Was this plugged into a Evap canister? Someone got rid of the can and hooked up the wires a different way? This bike has a S&S super E Carb and a vacuum sensor hooked up. The gas tank breather is just a hose that runs down and out.
Can somebody please tell Me what this box is for? One of the wires travels all the way to the front of the bike into the box with a heatsink just behind the front tire. Another one of the wires I can see goes into the harness near were the tail lights plug in.
I'm Guessing that the starter has a built in solenoid so one of those power wires is going to the starter solenoid and the ignition switch is ground? I could be wrong.
What is the purpose of that power box?
Maybe someone can help me out heres a pic:

I believe that silver box is the starter relay. The other stuff I'm not so sure, except the canister looks like a charcoal canister for evap control. Is this an old California bike?

The item in your 3rd photo is a 30 amp breaker. It, and your wiring need attention!
-The positive battery cable connects to a terminal on your starter. Attached to this same starter terminal is another wire leading to the copper colored post on the breaker.
-The other terminal on the breaker should be silver colored. Two wires are attached to it. (1) Voltage regulator and (2) Ignition switch on your console.
When the engine is running, voltage is supplied from the regulator and through the ignition switch because they are both connected at the silver terminal on the breaker. Voltage also passes from the regulator, through the breaker, to the starter terminal and back to the battery. When starting the bike, massive amounts of amperage is drawn from the battery by the starter. If the starter should fail, the 30 amp breaker will prevent excess amps from feeding into your electrical system. I've seen these breakers improperly wired bypassing this safety feature.
These breakers are not warerproof and can corrode internally after time. They are inexpensive. Replace yours, clean all the contact points and coat everything with dielectric grease.
In 2007 Harley eliminated this breaker and replaced it with a 40 amp Maxi Fuse.

I checked the speed sensor and that wire goes up to the top of the frame and plugs in with the same 3 prong connector. Any other idea's on the unused plug?
This bike came from Florida.
Also were should I be mounting this 30 amp breaker? Is there supposed to be a plastic box it sits in that mounts somewere?
