so im riding down the 5 when my r1 lost ALL power and wouldnt bump start. i pulled the plug to the rectifier and thsi is what i found



i dont exactly know what to do here, i cant get the plugs even through yamaha. i already baught a new stator but im tryin to avoid having to put it in. any ideas what would cause this ? i need to figure this out since its my last resort for transportation right now so ANY help at all would be apreciated!

 

first the stator and regulator/rectifier make up your charging system. With the rectifier fried like that you ONLY need a new R/R not a new stator like you mentioned... So I hope for your sake you didn't buy one... Also on ebay typically they come with those connectors but I just crimped mine together since I used a non oem R/R on my superhawk.

 

this is classic for many manufacturers... the aprilia suffers from this from time to time... we get around it by bridging the connector... or using lower Resistance wires and rewiring that portion of the harness and USE dielectric grease... this can be promoted by water getting into that connector. this rec/stator plug has been know to cause fires if the right situation arises, eg gas, but its good you found it in time. everyone should regularly check this plug for discoloration.

Again, this is a Resistance problem and is NOT related to one manufacturer.

 

my r6 did this a few times and my 748 just did. i hardwired everything with a higher gauge wire.

 

how exactly od i go about hardwiring it ? just use connectors onto the pins? if so how do you keep them from gapping when wet ?

 

just eliminate the connector all together or run a bypass in addition to the connector to reduce resistance
