low voltage lights

Postby brandonb » Sun May 27, 2012 9:11 am

Hi, newbie here. I have an 84 gla, I like to be seen at night, so I installed external lights. I have 3 separate systems.
accent lights, and 2 sets of piaa driving lights to see at night.
The problem is all leads go to battery, and I seem to be draining the battery when I ride at night. Is this normal?
Can i get these lights off of the direct hookup from the battery and perhaps tie them to the main fuse in the counsel?
Will I screw up something else? Any and all thoughts are truly appreciated.
PS love this site, so much useful information for a novice like me.

Hi Brandon, I hate to be the bringer of bad news, but yes this is normal. Your bikes electrical system is marginal at best, adding a 100+ watts of light bulbs to the system will drain the battery. Some people try to save power elsewhere by using LED bulbs, but you are going to be very just with the extra lights that you added. You might want to see if you can replace the 55watt bulbs in your driving lights with 35watt bulbs, not as bright but will give your bikes charging system a better chance of keeping the battery charged. Others will probably be able to give you some suggestions.

Hello and welcome to the forum.
You may want to try LED bulbs, they are bright and hardly draw power compared to incandescent bulbs. http://www.superbrightleds.com/cgi-bin/ ... 2Fdrl.html

+1 with what the others said. Change all the lights you can to LED's and use 35 watt bulbs insted of the 55 watt. The goldwing charging system is marginal, at best. You can always do the Poorboy alternator conversion for optimal charging.
You can also do the HID headlight conversion.

Thanks for the advice.
Heres what I have done, I took the LEDs and one set of lights to the accessory block. The block was putting off nearly 11 amps. Then put one set back to battery. Was getting nearly 13v back into battery when running. Will be looking at an HID conversion kit also. Poor boy alternator may be beyond my scope at this point.
Next up, radio conversion. May need a whole lotta help with that one, lol

Thanks again,
Keep the shiny side UP :D
