Topic: HID install gone wrong

[oldk6guy]

i purchased a plug and play HID headlamp for my 76 cb750. i got it all hooked up and installed. turned the bike on and....nothing. started it up and then theres light...with enough revs...turned on the left blinker, no light. turned on the right blinker and the light flashes with the blinker. my blinkers are all tiny little 6 led lights and tail lights are led as well. any ideas on how to fix this?

If the turn signals worked OK before, it sounds like maybe there's an incorrect wire connected. Old man Honda has color wiring diagrams. download one and re-check your work.
In case the signals didn't work before the headlight install, signal indicators work through grounding the signals. You may need resistance to make them work with all LED's.

the only wires needing to be touched for that setup are the blue/white/green that attach to the sealed beam headlight.
if you are not getting power to your winkers, and they worked before, you've dislodged something in the headlight can, or, your battery has drained.

did you install a relay?

The blinkers work fine. They didn't work at all when I bought the bike. The wiring is a mess actually.  Someone got in there at some point and messed everything up. I did my best just to get all the lights functioning properly. And they do with the stock headlamp. Its just with the HID headlamp the headlamp goes out as soon as I turn on a blinker. The led turn signals have load resistors and function properly now.

This sounds like low voltage: is your fuseblock the type with glass fuses? They are likely the culprit, if so. Otherwise, look for dirty bullet connectors and bad grounds.

+1 HID's are temperamental when the voltage gets down

Easy way to check for a problem with that fuseblock is heat -- if the glass fuseblock gets ridiculously hot within moments of turning the ignition on, it needs to be cleaned.

it is the old glass fuses. i was thinking of switching it to the blade type fuses. you guys think that would help?

It sure won't hurt Just unplug and take out the two bolts and plug this one in.

If you have some 400 grit sandpaper, you can clean up the old block in a half hour. Disconnect the battery, unplug the block, remove all the fuses.  Rip off a small piece and wrap it around the end of one of the fuses with the sand side out. Roll the end of the wrapped fuse in the brass holders  to clean them up (takes a bit). Should change the color from a dull brown green to shiny brass.  Spray it down with electric contact cleaner (MAF sensor cleaner works too) once you have the tabs cleaned up.  You may have to squeeze the tabs a bit to make sure they grip the fuses like they should.

You'll want to give the sandpaper treatment to the bullet connectors on the fuse block plug. I usually use dielectric grease on those as well when reconnecting.  Might as well clean up the bullet connectors around the rest of the harness too, while you're at it.

I used to do that, until I got Del's crimper and connector kit(s) from www.vintageconnections.com. Now I find it easier to just replace them, and the new ones are much better quality brass instead of zinc'd steel.
