Stator and R/R locations

[BigLenny]

Hey Folks,

 

Yep, I'm facing the ol battery, stator, r/r problem. The bike (2007 RSTD) stranded me and my wife today in the middle of nowhere while we were on what we thought was going to be a relaxing ride on a beautiful Arkansas day. It was doing all of the typical symptoms that have been described here as being battery, stator, R/R related.

 

I have the battery on a charger for the night, but, I will begin the rest of the investigation in the morning.

 

I have a basic couple of questions: Where is the stator?

Where is the R/R?

 

I am not an electrical wizard. My first gut feeling is to check all of the connections and replace the battery, stator, and R/R and get on with riding.

 

Please advise.

clutch side......by the shifter...if its like a 83 ... you may get better response...in the 2nd gen tech talk....

I'm going to assume that the RSTD is the same as the RSV in this instance. The Stator is on the left side of the engine behind the large chrome engine cover. To remove the cover I needed to loosen the left side exhaust so as not to scratch the cover as I removed it.. The stator is bolted to the inside of that cover. There is a set of 3 wires coming out of that and going to a plug under the seat and sort of under the battery box.

The regulator/rectifier is at the bottom and behind the center of the Radiator. It is held on by 2 10 Millimeter bolts.

Simply replacing everything is an expensive way to go. Most important thing is to check the connectors. I Have a friend with a TD that recently broke down because of a slightly loose battery connection.

 

In the tech library you can find a link to a service manual. That and a $10 multimeter from Harbor Freight will help you diagnose the actual problem(s).

Once the battery is charged, check the voltage at the battery terminals, at idle should be 13ish volts, rev it up it should increase to not more than 14.5 or so.

 

If the increase goes north of 15 volts , shut it off, the regulator is shot and not regulating, that will fry your battery, and it can explode.

 

If no increase when reved up, could be Regulator is not letting stator voltage thru or stator is not producing voltage.

To check if the stator is working, pul the regulator down and disconect the plug on the back. Check those contacts in he plug and the regulator to see if they are burnt or not.

Start the bike and check for AC voltage form any of the pins on the plug to any of the others, you should get something north of 16 volts, check all 3 possible combinations (A to B, A to C, and B to C) they should all be the same. If no voltage or an inbalance your stator is probably shot, I think there is another connector in the stator to RR circuit further back on the bike near the back of the battery that is exposed to the elements and wash from the rear tire, some times folks have found that connection to be bad also.

Hopefully some one with experience with that connector set wil chime in.

Here is one of the best articles on the subject I have read. I hope it won't be a problem to post a link since it is a competing site. If it is against the rules somebody nuke it.

Also I have seen a R/R pass the tests and actually be bad. If it fails it is definitely bad but not failing does not prove it is good. The manual says to test everything else and then decide it is the R/R if everything else passes. At over 100,000 miles I have been through this a couple of times in the last couple of years. The first time it was the R/R. The second time was the stator.
