Thanks for reply, Ohm was at 1.1.. BUT last season I had a headlight issue which the main beam didn't work, the left of these cables were loose and a friend added it back on which makes me think it has to do with the light or is it in series with ignition? Just weird a thing like this isn't in the wiring diagram.Measure its resistance and I'd say it will be between 1 and 3 Ohms. In which case it is the ballast resistor. Should be in series with power to the coils when key in Run and the Start button not pressed on may Hondas. Purpose is to reduce coil current (thus heat) when running by reducing the voltage to the coils.
I've seen ballast resistors used to simulate a high and a low beam, before. Not recommended, however.I doubt that it's a ballast resistor. They are usually ceramic to insulate the heat that they generate.
And why would anyone wire it between the fuse and the headlamp?
It looks like it might say Radio ShacK on the component.
The headlamp switch should get power from a fuse in the fuse tray via a single connector.
I would take it off and throw it in a corner and connect the headlamp (dimmer/dip switch straight the fuse box like it;s supposed to be - without that think in the middle.
this seems likely. i tried going around this thing and i couldnt use passing light. High was far stronger than before though. so im guessing without this you wont notice a difference in the light beacuse its already at max capacity and thus cant shine brighter, so its been used so you can use pass. Question is however, is there any law on having passing light?Could it be for a passing light?
