Fuzeblock install

Thursday, Jul 18 2013 [475 miles]

I haven’t ridden the bike since Sunday. This project started Monday. I need to finish up the wiring mods and take a ride. Fuzeblock and Hella Fog Light relay wiring is all that remain.

I crimped and shrink wrapped the leads to the relay for the Hella Fog lights. Two of leads provide power to the lights; one of those leads is ground. Another lead is power from the fuzeblock. The last lead is from the fog light switch. There are two other leads (power and ground) for the switch. They are wired directly to the Fuzeblock. The switch includes a red and green led.

The above sequence shows how I grabbed power for the fuzeblock. I pulled the battery out of the case thinking I was going to attach the hot lead directly to the battery. I didn’t see an easy way out of the case if I did that so instead decided to attach the hot lead to the jump start post. Ground will go directly to the battery.

The first image shows how I routed the power leads to the fuzeblock. Hot is on the left, ground is on the right. I trimmed the wires some, wanting to leave slack to work on the fuzeblock in the future. I also wanted the result to look halfway decent. Halfway is about what I got.

There is a always hot capped SAE plug curled up in the under seat cavity. It’s on a 10 Amp fuse. That’s what I’ll use for things like my air pump or hooking up a battery charger. What I didn’t hook up was power for my heated gear. Seams I used that SAE plug on my /2. I’ll order a new one. Maybe a coax version instead of SAE so I can ditch the SAE-to-Coax adapter on my heated gear.

Before re-attaching the battery I put an ammeter in line to check for current draw. Less than 10 mA. I didn’t bother putting the ammeter in the low range so don’t know the exact parasitic draw. Next time.

Turn ignition on… all is well. Start the bike… a second or two after starting I have fog lights and the the P3 lights start modulating. You’ll have to trust me about the P3 lights… the picture doesn’t show anything interesting.

I took the bike for a ride. It didn’t catch on fire. I’m going to call the job done.
