Reply To: Regulator plug wiring – 2008 GT250R Carbureted model
It was probably done to help the regulator add more juice in the extra lines towards the battery itself before the main-harness feeds it.
The main harness has a red wire from the regulator , that trickles down to the fuse box and then the red wire starts going to the battery and various other places for +12V supply , sometimes it will run to the front of the bike, and then orange wire takes over as the “Switched 12+v” (for when the key is turned on , that orange wire gets active etc.
So i would advise to add an inline-fuse at the END of the red spliced wire –> put a 15A fuse there (but 10A is OK too just for the regulator) –> Then connect red to battery and black to battery.
If you have other pictures just to confirm the connection between the stator plugs and harness looks good (the stator can easily send 90V AC x3 towards the reg and you want the plugs to not have oxidization issues or rust as resistance may go up = extra heat & a soon fried harness!) , feel free to post them. It is a sigh of relief image uploads are working, so now we can see what’s happening!
Correct me if i am wrong on anything i said regarding your bike.
