Bad signal relay?

Need some help diagnosing a signal problem. I'm rewiring everything for dev_usc's headlight kit. Using LP aftermarket turn signals needing 12v power. Replaced the battery with a new Gel-type battery. My turn signals are not lighting up, front or back. The back wires are registering 1mV and the front are registering 0.6mV. I tested signals on another 12V battery and they work fine.

Any reason I'm getting such low readings? A bad signal relay? Maybe using the wrong ground?

You say you tested the signals on another battery...., do you mean you directly connected them to the battery terminals to see if they work?

Have you replaced your flasher relay with a current independent one (the so-called "led flasher relay"). If not, this might cause your indicator lights to not light up when using your left/right indicator or hazzard lights.

My bike has to be running to test them

I directly connected the LP signal wires to a 12V battery via the terminals. I have not replaced my flasher relay. The signals light up. The relay is the same one from the factory when I bought in 11/2004 though it's a 2005 model.

That's what is throwing me off. With the hazards on, the lights should still illuminate without the engine being on. And even when running, the lights don't illuminate.

Have you checked fuses?

Fuses checked. Not broken.

Anybody have an idea why I'm not getting 12V readings?

I would definately replace your flasher relay with an electronic one...
My guess is that this causes your indicator lights not to work (as the load is too little).

BTW, it's just the one 10A fuse right?

Just check all your fuses to be sure
I've read on an old thread that someone had the taillight fuse burned out, but the light was still working.... But his indicators weren't

Motogiro, this the relay you're recommending for a quick fix?

Yes. as long as it's a 2 wire it doesn't matter what make bike it is for except for the plug. Red wire goes to 12vdc signal and other wire is the output. So the 2 wires for the bike flasher are brown with a green tracer that goes to the new flasher red wire or input. Then there is the brown with white tracer that goes to the new flasher black or output wire.

You may find they only have a Honda, Suzuki, Kawasaki etc. They only had a Yamaha when I needed a Suzuki but mine isn't plug N play anyway. If the plug won't fit just wire it up.

It was the TAIL fuse. Thanks everyone for all your help.

Yes the tail fuse feeds the flasher. No Flasher and you seek out the answer. Oh! No tail lamp!
