Adding headlights and handwarmers?

Just picked up a Northstar (Murray) 29" with 10hp Tecumseh in excellent condition. Has a stock halogen 37.5w bulb, no hand warmers.

I would like to add some Cree LED flood lights to the front of the blower housing and hand warmers. The floods are 18w x2 and the hand warmers are in the 40w range.. So I'm looking at right around 80watts if I don't use the stock headlight.

I have a multi-meter but not quite sure how to take a reading to determine if the electrical circuit that runs the single headlight puts out enough current to run this new setup. Last thing I want to do is burn out a stator that may be impossible to get replacement parts for.

Hoping someone here has some experience with this sort of thing. Before I go off and start buying this and that I want to make sure it will actually work. The bulb for the headlight is 12v so I'm assuming it's a 12v charging system and not a/c like some of the newer blowers out there.

Most likely you have around 12-18 watts AC on that circuit. Most likely you have very little more available amperage than what the original halogen bulb is rated for. So you need to work within the wattage of the original bulb for anything electrical.

Go through this thread entirely before proceeding.
Good Luck

Thanks, I'll do some probing tonight and see what my numbers are. I work with a ton of electrical engineers so someone here can tell me what I'll need to do in order to get my numbers.

I'll report back what direction I end up going. I have a 200' driveway and will mostly be blowing in the early AM before work and late PM after work... Long commute makes it dark when I leave and get home in the winter months....

Nothing really more you need to do other than switch your multimeter to AC, put one lead on the metal frame of the snowblower, and the other lead to the headlight circuit wire (while still having the light connected and ON) That will tell you that you are dealing with about 12-18 volts AC. Then you take the wattage of your bulb, with the voltage you got when you tested and you can do your amperage calculation. It doesn't change the fact that you simply don't have enough amperage available to do what you're wanting, there is barely enough to run the LED lights you want. The only way you can run hand warmers as well is if you happen to have another circuit on that machine that is meant for a starting battery or was intended for hand warmers.
