Need Help on Installing/Using an Auxillary Power Box

OK. I am not an electrical guru. And I am sure it is probably very simple.

I want to install an Auxillary Power Fuse Box. I have seen the different types and have seen pics of different ones installed. I need to know a step-by-step process of installing one.

I recently just installed a Powerlet to my V-strom straight to the battery, no big deal, very simple. But I'd like to add some extra driving/fog lights. Maybe down the road, some heated grips, and a couple of other do-dads. I do not remeber where, but I read somewhere that there is a limit to the electrical system on the V-strom; and I'd like to hook any do-dads up correctly and properly.

Once I install an Auxillary box, then I'll moved the Powerlet to the box, along with anything else I hook up.

Please help........... :!: :?:

You find a place where you want to mount it and do so. Run the hot lead and ground just like you did for the powerlet straight to the battery, fusing the hot lead. Using wire capable of carrying the total load the accessory box could possibly see, both the hot lead and the ground need to be the same size wire. To many people will only use a large diameter wire on the hot lead and use whatever is handy on the negative side.

The problem with this type wiring of accessory power outlets is that it is always hot, regardless if the bike is running or not, meaning if you forget to turn something off or a passerby flips a switch like the grip heaters then you could return to a drained battery. If you don't need anything powered when the bike is not running then wiring the power to the accessory box via a relay to engergize it is the besy way to do it.

Buy a 4 or 5 pole relay from the auto parts store, you'll find them in a blister pack for under $5.00 in the driving/fog light section. As above run a fused hot lead and a ground wire to the relay. Connecting the hot side from the battery to the terminal marked 30, run the ground to #86. Terminal 87 will be the hot lead to the accessory box. And finally connect the terminal 85 to a power source that is only on when the bikes key is on. This need not be a high power line, you can tap into the brake light or anything else that is powered like the unused connector by the radiator.

So what happens then is when you start the bike or turn on the key the hot lead at 85 energizes the relay, sending power out of 87 to the box powering the accessories. If you have a 5 pole relay, the terminal marked 87a will be a hot connection when the relay is not enegized and can be used to power some item you want to use when the bike is not running. You would want to run this on a seperate circuit from the accessory box.

On fuses, even though the bike does have limited power to run too many accessories it does depend on load of each item, but the main fuse going from the battery to the relay should be rated for the entire load you plan on using plus 10%, regardless if you plan on using the total amount. One could forget and start the bike drawing too much power and blow the fuse. So add up the load, add your 10% and use the fuse available closest to that value.

Easy as pie, hope this helps.

I got a few other questions/concerns re: the auxillary fuse box idea.

Even though an auxillary fuse box is installed and all your do-dads are hooked to the box, one is still limited to what and how many do-dads one installs on the V-strom due to it's limits? Or for that matter, any motorcycle is limited? Is this correct?

The Powerlet site has some good info. on what a motorcycle's limits are when it comes to extra electrical do-dads.

http://www.powerletproducts.com/docu...scapacity.html

So, my question basically is..........

Can I run heated grips, a heated vest, and a pair of 55 watt auxillary lights, all at the same time? Would this overload the V-strom's electrical limits???

I am trying to find a set of 35 watt auxillary lights, which would obviously not tax the electrical system as much.

Anyone's input and/or two cents would be apprectiated...........

Thanks

There is only so much excess energy or watts available from the bikes charging system while it is running before you are running down the battery without it being recharged.

I'm not sure exactly what the overage is available on the different models of the bike, early 1000's had less than later, and I have no info on the 650. On my '03 I have heard numbers between 75-100 watts of excess.
Excess being the production above the energy required to operate the bike, the lights, signals, fuel pump, etc and leave the batteries charge where it is.

So running a vest, about 45 watts, heated grips about 36 watts, and 110 watts of lights or 191 watts will put you well over the power available from the charging system and be sucking the battery down to dry in no time. A vest and grips would be possible if about 80 watts were available or a pair of 35 watt lights but not both.

Add a volt-meter to monitor your system

Brand new to the VStrom world -- after years of watching, I couldn't hold out any longer and bought a used 650 last Saturday.

Anyway...

I've been runing a KLR650 for the past 3 years with a GPS, heated grips, and a heated Gerbing jacket in cooler weather. Now the KLR is notoriously anemic when it comes to excess power. Actually, it's anemic when it comes to most anything, but that's another story.... I have a voltmeter on my KLR and when I'm running 35mph or higher, I have no trouble keeping my volts well above 12 and 13. As I start slowing down or hit stop and go traffic, I'll turn off or turn down the heated grips and jacket. This works just fine since you don't really need heated gear at the slower speeds as much.

Bottom line: as long as you're keeping the volt-meter reading a healthy 12.5volts or more, you'll be fine.

Caveat: I have yet to add a voltmeter or any electrical gear to my new strom, so I have no idea what to expect. I'm *hoping* it'll be at least as powerful as my KLR...

We carry the Electrical Connection Aux Power panel that contains a fuse panel wtih 6 seperate circuits and a relay so the accesories are switched off with the bike. It's a very well thought out kit and easy to install.

All of the Aux lights kits we sell for the V-strom are 35W each and will help with management of the limeted available power.

The should be listed in the electrical section for the V-strom 650 and 1000 on our site.

Yeah, I saw that stuff, very nice set of lights. I will probably order that light kit down the road when I get some extra dough.

Thanks,

saving power

there is a pretty nice set of low wattage HID lights available at http://www.trailtech.net/motorcycle_hid_parts.htm.

A couple of folks from the other board have them and like them. you can search for HID on the other board to read the discussion.
