solid state reg/rect

on my 77 Kz400,i have a shorted rectifier. this is the old type with the separate voltage reg. I have a newer solid state reg/rec combo.it also has 3 wires coming out plus the fourth that goes to the battery.my question is this ,one wire is black the other two are yellow. can i change the connector head and use it ,or do i have to change the stator? thanks to all.

Sounds like it's the wrong type of reg/rec combo.

Ibsen will know better, but I think your bike uses an excited-field alternator. The reg/rec combo would need the same number of yellow wires, plus a ground wire, a positive wire, and a wire to the rotor. Some combos also have what's called a sense wire (usually brown).

Where did you get the reg/rec combo, and/or what bike was it intended for?

Solid state... as opposed to tube powered?

Sorry, just had to ask...

Solid state as compared to mechanical (regulator).

You spend too much time with amplifiers :laugh: :laugh:
