voltage regulator wiring

[amclimber]

I have what I think is a Stens 435-163 voltage regulator on my scag walk behind (kawasaki engine). There are 6 wires that come out of the regulator in order as follows:

Dark Blue (or maybe black)
Yellow
Red with White Stripe
Black with White Stripe
Orange
Yellow


The black with white stripe and orange wires both go to a condenser.

I'm looking to know the functions of the remaining wires.

Thanks.

Post both the engine model and spec numbers......

I think the electric clutch on the PTO may have been added to the machine (not stock). I was running the mower, and the blades just suddenly stopped turning. As I started looking things over, I saw that the large connector off the regulator was melted through, and a bunch of junk was in the terminals. I took the housing off and cleaned things up, and I'm not getting any output from the regulator. I think I may have the wrong wires connected to the inputs, so it would be nice to know what the inputs/outputs are supposed to be for the regulator.

On the two red wires from the motor (going into the regulator) I am reading approximately 9.5v on one and 4V on the other. Is this normal?

Here's what Scag shows for your model number;

If I had the engine SPEC number (located on white bar code label on the engine block), I may be able to find a better diagram...... Oh..... From what I see that machine came with electric pto......

Thanks I had that diagram also, but I'm wondering what the actual regulator wires are for.

Maybe of these numbers is the SPEC you were referring to:

FC420V-HS09
E/NO FC420VC44513

This is the Kawi diagram for electric start but your rope start regulator should wire the same, This is all I can come up with......
