my original r/r one day when i started my bike it started smoking and melted the back. so i bought a new one and it started smoking as soon as i plugged it in ?? so i checked it with an ohm meter to ground and it shows resistance on both red wires and both green wires does anyone have any idea what has happened to my bike? 84 vt 700 c

It's impossible to say without doing some troubleshooting. Use the troubleshooting guides here--http://www.electrosport.com/technical-resources/diagnosis-center

thanks

ok thanks i will check it out

What does the white connector with the threes yellow wires from the stator to the R/R look like?

 

[Chris75]

Two of the slots in the plug are vertical and one is horizontal. The plug fits real tight

He means what condition? Does it look anything like mine did (below)?

That's not the connector I'm talking about. I believe the connector is under the left hand cover but I'm not sure. Should be 3 yellow wires on both sides. As Adlowe pointed out I'm asking what is the condition of the connector. If it's all blackened and burned that could be your problem.

I took it mean when he connected the plugs to the R/R before he even started the bike it started smoking. If that happened I would guess he has something other going on unless the stator is shorted out.

SMOKE???
Ain`t good!!!!
Gotta find the problem, these R/Rs are expensive, too expensive to smoke anyhow

LLLL bring it over

And I thought cigarettes were expensive @ $1.50 a pack

Good Morning HSN!!
I`m going outside, I will check on this afterwhile

Shorted stator wouldn't cause the r/r to cook with the bike off. It's got to be an electrical problem unrelated to the stator -- particularly if it's happening with the key in the "OFF" position. Seems like the "hot" lead is running juice into the "cold" one. Melted stator-r/r wires (the 3 yellow wires jpr1968 asked about) could have melted adjacent wires -- things are packed tightly in there. If the 3-yellow-wire connectors are no worse than mine were then isolating the problem becomes more difficult.

That's what I was getting at. I should have stated that the connector could have melted and melted through other wires exposing the conductors. Also look at the wiring going to the starter relay/solenoid.

EXACTLY how I took it. A shorted stator wouldn't do a thing. It's the r/r that is connected to the battery so those connections could be the problem. 3-yellow-wire issue could be enough to melt insulation of any adjacent wiring -- though I've never personally seen that. (I got to mine in time.)

Don't know why the r/r would be smoking if a "hot" lead is shorted to ground. The battery would be dead before the r/r got connected. Leads me to suspect that maybe the "hot" lead is shorted to the other r/r lead -- though I still think the smoke would come from the wiring rather than the r/r.

 

[jpr1968]

Maybe the battery is installed backwards. Might smoke the diodes.

three yellow wires

The three yellow wires that come from the stator and plug into the r/r look just fine. When i plug the big plug in on the r/r , the r/r starts to smoke with the key off so i hurry and unplug it fast

 

[Chris75]

before this happened

when i first got this bike going, the old r/r was letting the stator over charge the brand new battery causing all the acid to boil out and i had to replace it twice. then one day i started the bike and the r/r started smoking at the back where the plastic is. so i ordered a new one and as soon as i plugged it in it started smoking just the same.. now when i check continuity to the red wires to ground they show resistance and same with the yellow wires so i assume i have ruined the brand new one too??
