Title: Adding A Four Circuit Fuse Block Next to The OEM Fuse Block
Post by: frankenduck on October 07, 2011, 07:09:59 PM

I've done this on quite a few K bikes and like it because it puts all of your fuses in one place, fit's under all K bike side covers and is inexpensive.

You need to rearrange the relays in the relay box a bit and drill a 1" hole in the side of the relay box and then use a 1" grommet to pass the wires through.

The fuse block I use is a fairly common one and can be found via Googling "http://www.google.com/search?rlz=1C1DVCI_enUS409US411&ix=sea&sourceid=chrome&ie=UTF-8&q=four+raised+atc+fuse+block"

Here's the one I installed on my K75 Frankenbike:

I know there's a bunch of wiring options here. I'm trying to sort out how I want to approach this. It looks like the fuse block you've chosen has independent battery-side terminals, rather then a bus for the battery-side terminals.

How would you then make this fuse block switched? I'm thinking of adding a relay in the relay box, but if I use only one relay for the new block, then I've created a "trunk" line to power the new block, and shouldn't that trunk then be fused on its own? Where would that trunk fuse live? buried in the relay box? In-line near the battery? Can I instead just put in a 40-amp capacity trunk and relay and keep the sum of the fuses in the block less than 40A?

What about grounding? My bike has one very small looking wire connected to the battery negative terminal. Should I replace this with a bigger ground strap? Add a second ground strap?

Thanks in advance. Your posts are super-informative.

I had planned on tackling this and my new Eastern Beaver headlight relays this weekend. Had been running on fumes in anticipation of removing the tank.

When I got into the relay box, I found there was less space than I remembered.

Duck, have you done this job on an "early K75/K100"? (http://www.motobrick.com/index.php/topic,536.msg1309.html#msg1309). The flasher relay that lives right where the wires should go through is freakin huge! where/how to relocate and secure that big beast? I have plenty of 3M Dual lock, (http://www.amazon.com/3M-Profile-Reclosable-Fastener-10-Foot/dp/B0006HVM72) but there's no easy solution jumping out at me.

I'm collecting parts to add a four circuit fuse block to my K75.  However, during my researching, I came across a 3-circuit circuit breaker block for motorcycles which looked really interesting.  It is sold by Revival Cycles and is the only supplier I've yet found who sells this unit.

Waterproof 3 Circuit Breaker / Fuse Block (http://store.revivalcycles.com/collections/wiring-connectors/products/waterproof-3-circuit-breaker-block)

This unit is ordered either with fuses or with mini-circuit breakers -- the choice is up to the buyer.  At the time of ordering, you specify the three amp capacities you desire.  You get to choose whether to ship unassembled or assembled.

The beauty of circuit breakers is taht you don't have to carry around spare fuses, which helps if you're on a long tour and not near a town that can supply spares.
