Question 530EXC Headlight, Taillight, Brakelight not working

Suddenly the head light, the tail light, and the brake lights stopped working on my 2009 KTM 530 EXC. Turn signals, horn, odometer, starter motor all work fine. Bike runs fine. I am trying to find what is common to the non-working bulbs in the schematic and it appears that there is a yellow wire going between the generator and the rectiifier that is common. Has anyone had this problem before? Thanks

Yep, the voltage regulator is bad. No change in battery voltage whether shut off or idling or reving. 12.4 volts . With each start of the bike, the battery is going down about .05-.1 volts

Well, I will know soon enough if the regulator/rectifier is the problem. I've gone ahead and ordered one. I hope it is as the electrical components are not returnable.

Well, it is not the voltage regulator. Still no headlights or tail lights. Bike runs and turn signals work, both of which are on the battery side. Looks like it is something in the charging system. Any one need a new voltage regulator/rectifier?

did you ohm the stator?... check the running output?...

Have you checked the headlight bulb? It's not uncommon for them to fail and short everything out.

Yes, I believe I did anyway. I measured the white wire to ground (4.8 ohms) and the yellow wire to ground (about the same). That reading is way too high if it is the correct measurement.

Outputs on AC scale were only about 2.5 volts yellow-ground and white-ground with bike running and rectifier plugged in.

Must be the stator, eh?

Seriously? I'll check it.

i believe you check the resistance between both stator wires... pretty much the same on all of them..... i think it's supposed to be less than .6 ohms?.... more, and they're shorted.... google it, it's pretty standard.... you gotta manual?....

when they're running, the ac voltage is like 18 at idle, and goes up to like 60 w/the throttle?....

2.8 ohms White-yellow. Sounds like stator is bad.

New stator is here. I am a little concerned, this is the same reading I got earlier (see above, 2.8 ohms) on the existing stator. Not sure what else there is besides the Regulator/Rectifier, which it is not.

Something is shorting it out. Did you check the headlight bulb? If it's OK, check all the AC wiring for damage.

The headlight bulb IS bad. The base twists on the bulb, but it shows as an open circuit. I removed bulb but lights still do not come on. Wiring all appears fine.

Not the stator either. Still no head lights, tail lights, or charging. Guess the wiring harness is all that is left. Hope I didn't make a mistake buying this bike. Never had electrical problems on a bike until now. Arrgh.

You've got to be right. By the way, pulling the yellow wire on stator I get about 8 VAC at idle and up to 60 VAC while revving. So it is not the stator.
