    would be nice if someone made replacements for the 87-88 bikes...

    Do u all think my lights will work tho? I checked today with a multimeter and at idle Im only getting three volts thru the yellow wire and maybe ten with a handfull of throttle. Do u think the rectifier regulator will be output 12v DC consistently enough to charge the battery? Or should i just run the led right fromthe regulator amd skip the battery step. Im afraid it will harm the led when voltage drops so low at idle which is why i decided on a battery.

    If you ditch the battery set up, then you will be running an AC set up. LED bulbs won't work with AC !

    If your lighting coils are working correctly and they have enough power to run the lights you need, then just use a voltage regulator and an AC set up.
    The only fly in the ointment is if you need a horn ! AC horns require more power than a DC one. I cannot get my 390WR to run one, and that is supposed to have 35w + of juice.

    the regulator/rectifier should take care of the dc problem, and the led will need dc power. i think your setup sounds good but i dont know about the battery

    I know the leds cant use AC. I had two options. Run the regulator/rectifier and battery so the battery makes up for voltage drop to the led and the coil charges the battery. Or run just the regulator/rectifier and have the led dim at idle.

    perhaps try it set up just feeding power from the reg, then after that adding in the batt?

    Hey guys. So i got some of the stuff i ordered in the mail. The important stuff. Got my switches, the led bar (pleased with the quailty, tested on twelve bolt battery and was nice), the rectifer regulator, and the headlight mounts. The head light mounts wents on easy and then added the led bar. Then i had to mess with my wires because i had them temporarialy ghetto rigged so i could ride it but they werent wrapped in anything so they were swinging everywhere and the gromet on the cover wasnt there so it was really ghetto. But i installed the new groment and im wrapping the wires in electrical tape. Since i havent got the battery yet i proceeded to test with what i had. I ran the two yellow wires on the rectifier/regulator to the yellow wire from the motoplat then the other yellow to frame ground? Is that correct or do i run the secind yellow wire to a different place? Anyways i then connected the red and black dc wires (i assume it had no instructions included) to the led and switch. The bike fired up and i let it warm up to perhaps charge the regulator capacitor a it bit. flick of the switch and high revs, no light. I got a few pics will upload when i get home. 20150424_115240.jpg 20150424_115244.jpg

    when you get the rectifier in series the yellow wire is the power wire for lighting and charging
    the regulator is just a dump, as in it dumps over volts

    I have said it already I know the led needs DC thats why I have he rectifier regulator to turn it from ac to dc. My regulator rectifier has four wires: two yellow and a red and black. I assume ghe two yellow are the alternating current input/output and then the black and red is pos neg dc output. Correct?

    No
    It did not. Online it said some stuff but was not that clear. I purchased the model suggested above by a user it is the SPI model ot something. Small silver box four wires. No real diagram tho

    from what i gather online about the spi..
    yellow wires get connected to your yellow wires
    black goes to chassis ground
    red wire is the power wire for your light

    hopefully something did not blow in the spi unit hooked up the way it was

    This is what does not make sense. The spi has two yellows and I only have one yellow from the motoplat. So what is the orientation of connection

    i would try just leaving the one yellow disconnected then. im betting the spi unit just is like that in case you have two outputs from stator. remember the led light may be polarity sensitive, so try switching the lights power and ground if it doesnt light
