I have noticed that everyone is using power straight from the battery to power up the amp, lights, horns, etc. That means that all of these items will be powered up 24-7. That can't be good for the amp or other items. Has anyone done something like this. I seen that there are open aux power plugs that are not used in the fairing. So for any of the Electrical Wizards out there, please comment. The 3 big items that I am going to put on it is the Rockford 300W 4 Ch amp, Bad Boy air horn, and driving lights. I don't think they will draw more than 30 A in total. But, I would really like feedback.
Well, you have some comments on the Rockford already. And as I've never added an amp, to any bike, I'll pass on that.
Regarding using a power panel, fuse block, that sort of thing, sure, that's a common practice on bikes. I've added fuse panels on prior bikes, but haven't felt the need (yet) to do so on my XCT. Here are some vendors of that sort of thing:
: Arboreal Systems Dispatch 1
: Blue Sea Fuse Blocks
: Centech Fuse Panels
Denali PowerHub2 fuse block, master ground block and wiring harness for motorcycles | TwistedThrottle.com
: Denali PowerHub2
: Eastern Beaver Power Center 8
: Electrical Connection Power Plate
: Fuzeblocks FZ-1
: Rowe Electronics PDM60 Power Distribution Module
Also of possible interest might be this ground block, depending on how bare-bones of a fuse block you get:
: Electrical Connection Master Ground Block (which I used on a prior bike).
Also, in order not to glom up battery-terminal bolts, you might be interested in this:
: Powerlet Termin-8 (which is what I have on my XCT).
Two similar products are:
: Eastern Beaver 3-Circuit Solution
Accessory Fused Terminal | Load Equalizers & Adapters | Lighting | Kuryakyn
: Kuryakyn Accessory Fused Terminal
I have my horn, for instance, powered by the battery (via a Termin-8), but it's through a relay, which has as its trigger the old horn power lead. So I don't know if you want to call that "directly" or not, but, yep, it's powered by the battery.
Pauljp has two excellent videos in this area of adding electrical farkles. The first one is horn-specific, and the the next one is about adding a fuse panel:
I hope some of this helps.
