Stator wires go where?

My first post here, already cheating though. I know there are wiring diagrams out there, and If I knew how to read them I probably try to figure this out. I have a 19.5 B&S twin opposed(?) engine (model 42E707 1631-01) I am mounting from one Toro Timecutter 42 to another. The engine was transplanted onto the one I am removing it from and the past owner gave up on it because the battery always drained down, and I attributed that to the stator wires never being connected to the wiring harness and if I understand it correctly, perhaps this motor's electrical output may not be enough to charge the battery if the PTO is engaged. But one problem at a time here. Now that I have successfully mounted the engine on a slightly newer Timecutter, I'd love to connect those wires correctly to something. If you refer to the pictures you'll see a black wire, an orange wire and a blue wire. The second picture is of the solenoid area just in case one or more of the wires go around there. If you also know an easy way to get enough amps up off this motor so it can charge the battery and run the PTO, I'll kindly look into that modification too.

I tried various ways to post two photos but it looks like I can only do one for now.

Re: Stator wires go where?

Most likely the opposed engine only has a dual circuit stator which can only produce 3A; unless, there is a voltage regulator added then it is 5A. The PTO can be pulling anywhere from 3A to 7A. Anyway it still would not enough for the electric PTO and to recharge the battery at the same time. You to the stator to a higher amperage version with a voltage regulator.

As for wiring things up I would need to know the model number of the Time Cutter so I can see what the wires are going to.

Re: Stator wires go where?

I will get that info later this afternoon when I return home from work, but I at least can now post the second photo!

Re: Stator wires go where?

The Alternator should be a Dual Circuit wit-
RED & Black wires.
Black is AC for headlights.

RED will go through a DIODE to convert the AC to DC and on for battery charging etc.
There should be a "lump" in the RED wire connector.

Look at the attachment-

Note- The 3 Amp is "nominal. Actual output may be 2-4 Amps.

Briggs stators, & flywheels are pretty interchangeable. If you could find a junked similar engine with the Voltage Regulated output, you could do a parts swap.

Re: Stator wires go where?

Thank you Bill, I do have two wires coming from the stator, I see the diode, from that connector it continues on as a red wire in my first picture, the other wire continues as a orange wire beyond that connector in that first picture. Then you'll notice a black wire that goes into the connector and on the other side it comes out as a blue wire. The two blue wires come out of it, one looping around back into the connector and the other blue wire must go somewhere. That black wire also appears to originate from under the flywheel coming from the other side of the carburetor (looking at the motor it would be the left side, the stator wires are on the right side). So now I need to know where these wires connect. The red wire need to charge the battery, need where to connect that. The orange wire sounds like it would go to headlights if the zero turn had any. Is there another use for this wire, and where would it go. And finally that black wire which turns to blue, what is the purpose of that wire and where would that connect.

On another note the transplant was sort of successful. I was able to start the motor and drive it. Had to jump the solenoid to fire off the motor, turning the key didn't do anything. This is the way I had to start the previous mower, but with the way everything was kind of hacked, I just dealt with it. It would be nice to turn the key to fire it off. All I thought I needed to do was connect the large gauge red wire from the solenoid to the starter and I thought I'd be fine. Also, tried to engage the electric PTO but no go there too. There was one small ground wire that was about 6" long from the connector to where it was cut that was left on the tractor when I picked it up. I believe (from looking at my original zero turn the connector was attached to the same motor mount bolt that the battery ground wire is connected to, so that one I will try and trace to where it should go, maybe that is why the PTO is a no go now.

If anybody can help with these issues that would be great. Also Bill, I will keep an eye out from another junk motor with a voltage regulator, I'm a tinkerer...

Re: Stator wires go where?

Found that the small gauge ground wire that was cut matched with the same sized cut wire under a relay near where the fuses are located. Reconnected that and I now have a clicking noise coming from the solenoid when I attempt to turn the key to fire up the motor, and after jumping the solenoid to get the mower running, I now can engage the PTO. If anybody can help with where those three wires should connect to that would a great help.

Re: Stator wires go where?

This should help on the Toro Z420 wiring.

Re: Stator wires go where?

Thank you KE4AVB, I tried making sense of the schematic, even looked for a few more to see if they would help but I couldn't make heads or tails of it. I will try connecting the wire coming from the diode (if I'm following things right, that is the one that charges the battery) and splice that into the wire that goes from the ignition switch to the solenoid to provide what is essentially a trickle charge.

Re: Stator wires go where?

Actually if this one has the original wiring setup then you just tie into the violet wire going to the "A" terminal on the ignition switch so when the ignition is off the charging is disconnected from the to prevent battery drain.

But as I said before that dual circuit will not have enough charging ability to operate the electric PTO without the battery being drained. It will not be able to tickle charge when the PTO is active. PTO can drawn between 3-7 amp. You do need to upgrade to the 10 amp stator with a voltage regulator. Btw the stator max amps rating is at 3600 rpm and the engine will not achieve this under load due to governor droop will can be as much 400-500 rpm when @ max throttle

Re: Stator wires go where?

I've always wondered what would happen if you removed the diode and connected the stator windings so that you have a continuous set of windings with 2 wires exiting . I would then set my multimeter on AC volts and check the out put of the stator at full throttle. If it was 30 to 40 volts then the addition of a Kohler or Kawasaki voltage regulator should give you a decent charging system capable of running an electric PTO and keeping the batt hot.

Re: Stator wires go where?

Due to the design of the dual circuit it is not that simple as both the AC and DC stator windings are grounded to the engine block. On 9-20 amp stators the windings are completely isolated from the engine block. removing the doide just make you have two separate AC circuits.

Re: Stator wires go where?

Most likely the grounded ends are readily accessible . Depending on the direction of the windings you could hook them together [ no longer grounded ] , reinstall the flywheel and do the voltage measurement.
