Adding Running Lights

[92r100rt]

I want to install a set of after-market halogen running lights on my '92 R100rt. What is the best way to connect these? I am putting an actual switch in place of one of the mock switches on the dash. Should I connect these directly to the positive terminal of the battery? Or splice them into an existing lighting circuit (headlight?)? Or some other way?

Thanks

From the battery, run the power through a dedicated fuse, then through a relay. Use a low-powered switched circuit such as the parking lamp to activate the relay. Then from the relay to the light's switch and then to the lights. You can skip the relay if you like, but the relay is there to keep your battery charged if you forget to turn off the lights when you shut off the bike. Think of it as a back-up switch.

This sounds do-able, although it will have to wait until I get back from a trip down to Deal's Gap and points beyond. Something about taking on a task like this the day before a vacation raises the hairs on the back of my neck. Anyway, there will be plenty more riding to come.

Thanks to The Veg for the input.

You're welcome. I forgot to mention that if you don't know how to wire a relay, the information is readily available out there. I can't quote it off the top of my head though, as far as which pin wires to what but many relays have a little diagram on them for that.
Also be sure to get an 'accessory' relay, which is commonly available at auto-parts stores. This type is designed to run on 12 volts and to be energised for long periods of time.

TWT, be careful here. Adding running lights may over tax your alternator and run your battery dead. The RT alternator only puts out - I think - 270 watts. I believe that the iignition sytem take about 140 watts to run, then add up all your lights and there isn't much left over to run aux lights or anything else. My understanding is that if you add running lights with nothing else like a radar or radio or heated clothing or grips drawing on the system you'll be ok, but for example if you have heated grips or vest or pants installed then you can only run one aux light, not a pair, safely.

I think you can upgrade the alternator thru Motofix (??) . They replace parts in the alternator inabling you to have (I think) 400 watts. Something to check into. They have an ad in MOA Owners News.

I'd take the time to ask some technically seasoned people about ythe ability to add running lights and limitation that this may impose on you resepctive to adding heated clothing, radios, etc.

Just my inexperienced 2 cents.

they are easy to do. Try this site for relay instructions. (http://www.1728.com/project3.htm)

The 400W upgrade is from Motorrad Elektrik. Pricey- about $600- but the kit is well-made and Rick Jones (the guy behind Motorrad Elektrik) does an excellent job of backing the product.

Ditto on the relay.

What it does is keep the hot load from passing directly through the switch, which means the switch lasts longer and does not become a short in the system.

If you think you are going to be adding other stuff, while you are doing this install, you might want to lay in the wires for a series of switches, additional relays, etc. That way, later on all you have to do is "plug and play" for your next gadget or gizmo.

Thus far, I have:
- Cell phone adapter
- Radar detector
- Driving lights
- GPS

My wife fully expects to see me plug in the electric vest one day and burst into flames! :hide

I also appreciate this addtional information related to the relays and being aware of the alternator output. While I do a heated jacket I can count the times I've used it (2) in 2 years and I rarely ride at night which is when I mainly intended to use my running lights. I know they would help my overall visibility too. Having folks out in Riderland to bounce topics like this off of is another great reason why I am a fan of the MOA. Thank you.

I was tempted to be a smartass and suggest a long extension cord to the nearest Gold Wing, but I know you're looking for sincere input.

I've done the 400W "Omega" transplant on my R100. Pricey yes, but not as expensive as a new bike, or melting down your stock switches, fuse board, wires, etc. Your dealer can order the Omega kit, or you can contact Motorrad Elektrik directly.

To provide some additional fused power sources, I installed a Centech AP-1 fuse panel under the left side battery cover. (fabricated a bracket to hold it) A large "hot" wire goes to the panel. You feed up to 8 wires off the various fuses.

Definitely use relays for extra lights, horns, or any other major amperage draws. A "hot" (always on) wire runs from the battery (or fuse panel) to relays located near the component. The relay output goes to the component. The relay coil is activated by the stock switch or an accessory switch. With an accessory switch, power to the switch comes through the main ignition switch so it can't be activated with the key off. The other side of the relay goes to ground. Be sure to obtain a relay that has four contacts, not three. And check the relay to ensure that it has the schematic printed on the side. There are some "mystery" relays available for different car uses, and many of the parts folks these days can't provide information on wiring.

I did discover a 30A relay system at good old Wal Mart, designed for powering lights, wiring and all.
