Rectifier/Alternator Wiring Question
So yesterday, the plug between the rectifier and alternator (three yellow wires) shorted. Then I noticed smoke and quickly cut the wires and removed the melted plastic and insulation between.
My question is, do the wires have a specific order to be connected or are they all compatible with each other? Only difference my meter tells me is that one from the rectifier has a bit more resistance than the other two. I think everything is working fine, I Just found where the previous owner had tape on the wires and it looks like over time it chafed and shorted.
Thanks in advance!

Excellent. Charged the battery overnight; going to reconnect those wires, check the charging system, and take her for a spin with the new brake pads I just put on. Thanks for the reply!

I mean I'm only talking a very tiny bit more, not even half an ohm. Just wanted to be double sure before I Just hooked wires up and caught my bike on fire lol

Just to be sure I double checked myself. I thought I remembered idodirt Writing this
Basically, the 3 similar color wires come from the stator, which is just 3 coils of wire. As the flywheel that has the permanent magnets spin inside the stator thats attached to the alternator cover, it generates AC electricity. That's routed to the R/R which converts it to DC and regulates it so that it charges the battery. Since all 3 stator wires are coils, it doesn't matter which wire goes in which position.
The other 2 wires are the positive and negative wires.
The other 2 wires are the positive and negative wires.
if you rewire, make sure you use proper gauge wire.
failure to do so will put you right back where you are now quickly.
if possible solder the joints as well, and heat shrink to waterproof them.

Here's a place to get a replacement connector if you're wanting to keep it clean...
OEM-Type Bullet & Spade Electrical Connectors for 1960's through 1970's Japanese Vehicles... Bridgestone, Datsun, Hodaka, Honda, Kawasaki, Landcruiser, Suzuki, Tohatsu, VW, & Yamaha
And, yes, the 3 yellow wires are inter-changeable. just don't get the red (+) and black (-), mixed up.

I found a wiring diagram right after I posted this and when I saw the layout I knew I was in luck haha. 'Preciate the help!
