Let me sum this up, and see if I'm right. You have an aftermarket light that is both a tail light (always on) and brake light (on w/ brakes). It is a recent install, and worked when installed.
After a ride neither the brake light nor the tail function. Does the box that drives your light have terminal descriptions on it? Take a multimeter and check for 12V at the terminal for box power. Check for a 12V level on the tail-light input to the box with the ignition on. Check for 12V level on the brake input when you (or an assistant set of hands) apply the brakes. If any of these three do not show a 12V signal, check your fuses and replace as needed. If the fuses are fine, start looking for a fault in the wires leading to the light module. -Kurt On Sun, Jun 22, 2014 at 12:55 PM, Greg Haun <[email protected]> wrote: > WELP... my brake/ tail light, whatever you wanna call it, wont work. its > aftermarket. just a small round tail light that i can mount to my license > plate bracket located on the rear axle. i hooked it up and it worked... > took her out for a spin and when i came back i noticed it stopped working. > ive tried switching the wires around. nothing. the headlight works fine. i > have an antique plate so no turn signals. im seriously stumped. i changed > the little black box ("stop n' tail") between the tail light and the rest > of the harness. nothing.. can anyone help me? > > thanks, > Greg > > -- > You received this message because you are subscribed to the Google Groups > "Nighthawk Motorcycle Lovers!" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To post to this group, send email to [email protected]. > Visit this group at http://groups.google.com/group/nighthawk_lovers. > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
