Mr Viper,
I've been reading your posts on solutions to Viper electrical problems. It seems as if you get alot of requests so I have tried to do some leg work on my own by reading some of your earlier posts on various problems. I'll give you the brief synopsis of the problem. 02 Viper 6000 Miles. Runs great although the handwarmers stopped working and the head light was dim and when I hit the brake, head light would go off briefly (along with the dash) then come back on. I took the seat off suspecting a short in the wiring to the tail light. when I unplugged the tail light, headlight was full brightness and handwarmers worked again. I couldn't find a short in the tail light so now I am checking over the wiring harness and the stator. I read your post on how to check the stator and did that. With the positive lead of my multi meter in the bottom slot of the plug and the neg in one of the top leads, I get a reading of .65 (my multi meter ohm scale starts at 200) In the other top lead, I get no reading. Is this the way it should be?
Thanks in advance

Ok, I checked the wiring harness. Nothing worn through yet. I will beef up the wrappings on each section. Back to the stator, I get a reading on only one of the 2 top wires - I assume this means the stator is bad?
on the 3 wire white wire plug, with the positive lead in the bottom terminal on the lock tab side of plug, and the black lead on either of the top 2 wires you should read 0.36-.044 Ohms @ 68 degrees F.
I redid the test with the positive in the bottom plug and I still get no reading out of the top left part of the plug.
I have a good stator here, I will check for you, but your first reading is too high alone, let me check mine and I will post the actual numbers I have.
Get back to me as soon as possible as I ordered one from Port Yamaha this morning. I may still be able to cancel it. That .7 on my ohm meter - the lowest setting is 200, but I still get no reading out of the other.
Thanks again for your help!

we had a very similar problem on another '02 viper, extremely dim headlights, gauges wouldn't work, finally got worse until it wouldn't even run anymore. After looking at everything on the sled about 4 times we finally found a short in the taillight housing. Fixed that and it was good to go. The wrapping on the main wiring harness on that sled is now about an inch in diameter. Dont like electrical problems 
I get .36 on mine, both terminals. Your reading of .70 is a short in the stator.

Some meters dont read less than 1 ohm very accurately. Lead resistance also can give inaccurate readings. You can short the tips of your 2 leads solidly together then subtract that value from your reading of winding resistance. Remember, a dead short is zero ohms, an open is 1 meg ohm or more. If you are getting good contact on your wires it sounds like one of the windings is open.
"You can short the tips of your 2 leads solidly together then subtract that value from your reading of winding "
shorting your leads together would result in 0 reading on any scale.

On my Fluke 189 my lead resistance is about .3 ohms. On that meter I can short them together, press the "delta" button and it will read very low resistance (below 1 ohm) by automatically subtracting that lead resistance. Most Fluke meters will read .7 ohms or so on the leads alone. A cheap meter (no insults intended) set to its lowest range might read a very low but not shorted measurement at zero ohms. Measuring a coil resistance can be tricky. Remember a winding is just a piece of wire, long and wrapped around a core, but to DC current still just a piece of wire. An open winding is easy to find with about any meter though.

My 03 viper did the same thing. Went through and troubleshooted all that possible problems and figured out it was a bad stator
Just spent 3 weekends checking the exact same symptoms,checked all wiring and relays,dash would cut out whenever I hit the brake or high beam,When I checked the plug coming out of the stator only 2 of the 3 white wires were carring volts.(4.5V each)So my sled was only pumping out 9V which is not enough to run sled properly.I was having a power bog to and now thats gone.There was a broken wire coming out of the stator,Had to take stator apart and it was broke @ the solder joint to coil.Sled is running fine now,must have been bad from factory.It was a cheap fix but very fraustrating.good luck Jeremy
