How To: "fix rectifier plug"

That's because the stock spade connectors are unusually loose and tend to fry the harness from the heat generated by contact resistance. This write up by Ronin is to describe a fix without having to purchase a new plug (rare). If your plug is still good, this situation can be totally avoided by pulling the plug out and prying the female end of the individual connectors to make them grip tighter on the male ends. Then shove it back onto the rectifier, it'll be a bitch to shove in, but you know it is fukking tight now. If you have some good conducting grease (NOT silicon/dielectric grease), smear some on the contacts, it will help. FYI, my stock harness was so loose that it will slide right out if you push the catch, that's BAD considering the magneto is pushing out 300W (21Amps at 14V) through that tiny loose fitting +/- connector, small wonder it frys.

There's another junction that's problematic, and that's the 3 prong connector between the magneto coil and rest of the harness, lift the tank and do the same.

2yrs in the tropics, including riding in wet/rain, my connector is still fine.

THANKS,

just replace the wires. from the 3 pin white plug under the tank (as mentioned) to the R/R with new female connectors. That should fix your problem.

they burn to a crisp and no longer make contact, and thus the battery does not charge the battery.

It is much more common on the 99-02 bikes, but is still possible on the others

Its funny how everyone thinks replacing the plug and regulator is gonna solve the problem. Just give it a few weeks and you will be right back to square one.

who ever said to replace the R/R? it rearely goes bad.

but why dont you back up your statement with some substance...

Not true. They go bad quite frequently. In the stock location they tend to overheat because they dont get enough air. Notice where the 600rr has theirs mounted. Right in front near the radiator. The 03 regulator was redesigned and cools much easier. The best mod you could do for the 99-02s is use the 03-05 regulator and mount it up under the battery box near the edge to draw in a lot more air. You will notice the difference just buy feel. Also with the plug you dont always get a good connection so the spades are much better to use than another plug. I have gone through numerous burnt plugs and such and after I did that not a single issue. I have typed this many times and just dont like to keep repeating myself. Again this is prooved so you can argue it all you want but sit back and think about what your doing. Replacing the plug? I mean come on it doesnt take a genious to figure out replacing a piece of plastic will not solve the problem. Is that enough substance for ya?

2 yrs and going strong for mine. I guess mine's a production reject, the autodestruct feature failed. Mine's an 03, last I checked, people are still frying the plugs regardless, the RR is fine mostly, the plugs fry from contact resistance.

Did you not read the thread?

NO one in this thread has recommended to get a new plastic plug. I think i am the biggest opponent to replacing the OEM R/R plug with another one of the same. I just had this argument last week over this.

And The R/R rarely go bad on R6s. the platic connector gets hot and fries before the R/R gets hot and fries, so the R/Rs rarely go bad bad because the plug fails first.

I had to replace the regulator rectifier twice on my 03 R6.

So I was having this exact problem, pull my rectifier off and found my connector melted to the rectifier assembly and the green wirer completely burned off. what should i do? I really need a whole new connector. I think i have the worst case scenario. this sucks. Any help would be good. thanks

What size connector did you use? Also, do you know what gauge the wire is? It looks like it's a 12 or 10 gauge but im not certain.

By the way, although I'm sure you've heard it enough at this point, thanks very much for taking the time to put together that detailed "how to". Although it is a very simple process, until you actually do it, the pictures are extremely helpful. Also, anyone who was able to get those rectifier bolts off without using a special rachet, or removing anything from the bike must have some munchkin hands!

thanks
