HELP diagnosing dragon

[trestlecreek]

I dont think the Pro forum is the right place, but I think all of us that now ride a pro had experience with dragons also.... I have a buddy that has an 09 dragon 800, it ran fine up until today. Would loose all lights, dash info display, everything and stutter until she'd die. Wait 3 minutes, fire right up run for 2 miles then the display would shut completely down, loose head light and running tail light, then sputter until she'd die, wait another 3 minutes and run 2 more miles and do the same thing all the way back to the truck. We disconnected key, kill switch and tether.. didnt change a thing. Now my past experience tells me a coil is going out..? Any other ideas??? Thanks for your input.

Voltage Regulator...

That crossed my mind... Ive had 4 voltage regulators go out on me over the years on other sleds. When they go out, they wont allow the lights and displays to work after a brief cool down. When they go, they are done.... But I will back my theory by putting on a different regulator and see if that cures it.

tons of voltage regulator problems on those sleds. Eric

If you think it's the VR, I wouldn't keep running it. Replace it before it takes out the ECU and gets expensive.

What he said my son tried to limp his 700 dragon home and fried the ECU

Is there any fix for this issue? Having it on my 10 assault as well only has 278 on it and I've gone through two and possibly a third one

I think it comes from grounding problems clean tight a little Dialectic grease couldn't hurt
