824 Power Shift Tecumseh Alternator wiring to add LED Lights

Good morning all! I am new to the forum and a new owner of a used 824 Toro Power Shift snowblower which is like new. I have read through the sticky to add LED lights. I understand I need a bridge rectifier, fuse holders and smoothing capacitor.

My question is on the wiring I currently have on my snowblower. The lead coming from under the flywheel shroud has a three prong connector with three wires;

1 - black
1 - green
1 - red

In all the other posts I have read there seems to be just one wire that is typically yellow. My Toro is an 1989 model 38540 with a Tecumseh model HM80-155337N. When I look at the Toro manual for my snowblower it doesn't show any alternator.

I am assuming that it is a 10 AMP Alternator for a battery charging system. how do I wire the green, black and red wires to make this work for LED lights? How many watts can I support on a system like mine? I am mechanically inclined but I am no electrical. I will try to figure out how to upload some pictures once I figure out how to.

Thank you for any help you can provide!

If you upload the pictures on a place like photobucket.com, I think you can then copy and paste pictures.
Try copying and pasting a picture from google and you'll find out if you can or not.

You may have to do some probing with a meter while it's running looking for AC and or DC.
The Tecumseh manual I have says;

Tecumseh's standard engine wiring color codes, effective August, 1992 are as follows:
Code Product
Yellow - Alternator A.C. Leads
Red - Alternator D.C. + Leads
Brown - Alternator D.C. - Leads
Black - Alternator Ground Leads, Battery Ground Leads
Orange - 12 Volt Starter B + Leads
Dark Green - Ignition Shut-Off Leads
NOTE: PRIOR TO AUGUST 1992, WIRE CODES CHANGED ACCORDING TO MODEL AND SPECIFICATION
NUMBERS.

Thank you for your advice hsblowersfan. I only have 2 posts and the site won't let me post a URL to a link with the pictures.

Thank you dbert. My Tecumseh is a 1989 model HM80-155337N serial 8197R if that helps the wiring. I can not for the life of me find anything related to this plug on any manual from Toro or Tecumseh. I know it's factory stock and looks like it belongs there.

I am not much of an electrician but if you walk me through testing each lead I will report back what I find.

Snowblower runs like a top! One pull and it starts and runs smoothly. I just bought this 824 Powershift last week for $150 and it is built like a tank and looks almost new. Only other thing that needs adjusting is the Powershift itself won't shift. Everything else works.

Do you have a volt/ohm meter?
Since we don't know what color is what, I'd suggest placing the test leads in various combinations starting with AC selected on the meter.
While it's running that is.
It may have diodes already installed so you may have to do the same test with DC selected.

See some example alternator testing around page 50.
