HELP ME WIRE UP AN LED POD LIGHT (crappy diagram enclosed)

I am trying to install a small LED onto my craftsman 9/29 Snowblower. I HAVE NO LUCK! Enclosed is crappy wiring diagram. Please tell me if this is right. Please keep it in layman's terms.

did you check the dc out voltage and polarity ? ( disclaimer : i know just enough about electricity to get zapped and make things smoke ! )

Thank you for your response.

How do I do that. I know I need a voltmeter

yes you need a multi meter. they are cheap tho. also check the ac in voltage at the rectifier. could be as simple as a bad ground, or maybe your engine already puts out dc ? as mentioned.......i am no electrician !! its mostly voodoo to me.

Also if I wire the above way. All I get is Spark when I touch the ground wire to the blower.

start high on both ac and dc volts and work your way down on the meter. ( no need to start at 500v.....just set the meter higher than the voltage you expect to see for this purpose. any thing over 20v is probably a safe setting)

Is the sketch you made for a rectifier module you have? If so, you should be pretty close. Even if your alternator puts out DC, the rectifier should not prevent it from working. A normal full bridge rectifier will have 4 terminals, 2 AC inputs, and a DC+ and DC-.

Ideally you have a multimeter and first confirm that your blower puts out some voltage (either AC or DC). To do that, you take the multimeter, set it to ~V (AC Voltage), and touch the two wires from the blower (you have it labeled as AC POS and AC Ground). If your meter measures close to 0V, try turn the meter's dial to measure VDC. Hopefully it will measure something over 10V. If you measure voltage, you can reconnect the rectifier exactly as you have it in the diagram. Then, with the meter set to measure VDC, probe the terminals between DC POS and DC NEG. Hopefully it is within the range of the lights your purchased.

What's the model number of the blower? Maybe we can check out what alternator is on it.

can you post some close up shots of the rectifier and its markings .......not so much for me, but im sure the smarter than me guys will be along soon ! still check the output of your stator.
