I bought one of those replaceable bulb headlights from dratv and its extremely dim. Soo dim that i had to remove the new speedo, and high beam indicator bulbs to make it just barely bright enough to ride. i dont get it, the tail light is super bright(6v5w) but the headlight(6v15w15w) is dimmer than the old light with only low beam...anyone else had this problem? looked around and found other people with the same problem, but there bulbd turned out to be wrong, mine arent..:(
this is the headlight. http://dratv.stores.yahoo.net/nchewirebu.html
Make sure that the wiring is such that both elements are not coming on at the same time.
Also, make sure that the bulb is a 6V unit and not a 12V by mistake.
They do both come on when im on high beam! Is that the problem? What do i look for to fix it? also, the hi-beam ind. light is always on, yet iit gets brighter on high beam. nope, 6 volt
hmm, disconnected the resistor to see what happened. figured low beam would get brighter but it diddnt so it looks like both low and high are lighting up both elements, current seems to be leaking somehow...
how would the highbeam indicator be on in low beam? could there be current backtracking from the socket to the indicator bulb?hmm think i just figured it out that must be the problem... i must have messed it up somehow.....theres no way its suppose to be this dim
Just got done looking at the stock schematic. There are a million different ways honda wired this bike for different markets. What schematic is the us one it doesn't say in the book but it does give letters that I assume correspond to something in the vin number. But it does show that most of the models with headlight resistors were only a single filament and that the resister was used to just make it dimmer. Some had dual filaments and still a resistor while some also had dual filaments and no resistor.
If both elements are lighting up in series you are doubling your resistance making the voltage drop more accounting for your dim lights. That's your problem.
Attached is the wiring diagram for a '78 Hobbit
The wiring is pretty straight forward. Blue is your high beam, white is your low beam, and green is the ground.
It seems to me that you have mis-connected the wires inside the headlight.
The blue wire only goes two places, the high meam and the high beam indicator. The white wire only goes to the low beam. And the green is the ground.
Check it out.
There should be no power to the white wire when the switch is set for the high beam
