regulator rectifier testing help needed. bike caught on fire.

hey guys, need a little help from you gurus here about seeing if my regulator is still ok. so after a smokey flaming thrill ride this afternoon, i see that my stator wires have melted away catching the braiding on fire. fun times lol. so anywho, hitting the stator with the voltmeter shows no grounding out, but im confused with the regulator thingy. researching all i can see if testing on 4 pin regulators but ours is a 5 pin ( see pic). im guessing the leftmost 2 pins are grounds?(striped wires) but not sure about the top middle. when diode testing i get similar values on the rightmost two pins but nothing on the top center(cause of problem?). any pointers would be sooo helpful. thankx for any and all help. these forums always save the day for me.

 

Please read this and do the drill on post number 9

If it was me I will change out the whole enchilada :wink:

 

+ one with Scrubby, it is a know problem with these VFR's and from the factory they should have been fitted with a warning label stating "The wiring in the charging circuit WILL fail, please remove the connector and solder and heatshrink the wires" Problem is Mr Honda would never admit to the shortcomings of their lovely VFR but it would have saved a lot of people the angst that it causes

 

Thanks for the link! Ya, I realize I had soldered the stator wires maybe a year ago and it was those joints that had melted away. Looks like an upgraded regulator is the way to go. I assume the mosfet regulator can reduce the temp in those wires? Thanks again for the help, I shoulda realized I had seen this topic covered before, I was just in a flurry seeing what caused the meltdown lol.

 

Another +1 to Scub's post. Get all that crap out of there. Cut off any ends of any wires that looking even remotely off-colored or burnt. Get the new stuff, cut off any spade/plug in connections and get to soldering. I'm as mechanically inclined as a monkey with a chainsaw, but even I was able to handle doing all this.

 

The fact that it melted the solder indicates resistance, solder joint was the problem
