Using heated grips power for snowmobile visor

Wondering if anyone has used the heated grip power supply to power a heated visor on a snowmobile helmet?

We get serious winds here in Saskatchewan and would like some protection. I am concerned it would be too much power for the shield.

That would be nice, but you would have to know how much your engines electrical output is before you connected to it.

Garage:
MTD....2 stage(modern 8.5 HP) not my favorite
Honda HS622 TA-B - acquired at an auction- nice machine for it's size.
Toro S-140- Picked it up on trash day... it runs, sort of.
Yamaha YS 240 TB "Ricky" latest Craigslist find- on the bench now.

What does the visor require for power?

Not much of an electrical guy, but sleds run on 12 volt systems and most of the info I read say snowmobile visors also run on the 12 volt system. Not sure how much power it draws but I was thinking of using the heated hand grip power supply since I never use the heated grips. Can't see the visor requiring more than handlebar grips. Only worry is too much power and burning out the visor.

So here's the info I have found:

Ariens Platinum 30 has a has an alternator that puts out 60 watts on the 12 volt system. The light is 20 watts and the heated grips use 30 watts (leaving 10 watts to spare).

Most heated visors on snowmobile helmets are rated between 9.9 and 10.9 ohms (or approx. 1.2amp draw).

So if amps = watts/volts, am I doing math right:

60 watt alt. / 12 volt system = 5 amps power provided

30 watt heated grips/12 volts = 2.5 amp draw

So if I wire visor (1.2amp draw) into heated grips power supply, the visor would use 1.2 amps of the 2.5amp provided which means grips would still get 1.3 amps to heat somewhat. Correct?

Or

The electric technician where I work thinks I can just wire in the snowmobile helmet on the heated grip power supply and put a 2 amp in-line fuse for protection. I would then put a toggle switch that would allow me to either use the grip heaters or my visor.

Visors can run on both AC and DC power, so no rectifier should be needed.

Anyone here know if this sounds right? Or am I completely out to lunch?

I would wire it in with the heated grips and a toggle, 2 amp fuse. Should work great.

Going to try the following:

Replace the heated grip switch (single pole/single throw -- on/off) with a single pole/double throw (on/off/on) switch. Keep the heated grips wired the same and use the second throw hook up to send power to the heated visor. Will add a 2-3 amp fuse inline between switch and visor plug end and then run the ground back to the black main ground to the stator.

Well, tried running an on/off/on switch so I could have either heated grips or heated visor and then it dawned on me that the visor would end up getting the entire 2.5 amp supply the grips required and would likely burn out the visor. Duh!!

So went back to original grip switch and ran the grips and visor together with a 2 amp fuse on the visor line. Works great as visor is suppose to have a 1.2 amp draw or half the 2.5 the grips normally use. Grips warm up to half temp. May put a on/off in-line rocker switch on the visor line yet so if I want I can shut them off and have full grip heat.

Next addition will be dual 9 or 10 watt LED lights but may not be until next year as wife is wondering why I am already spending money on a new-last-year blower.

Amps are drawn, not pushed. For the same reason that your night light doesn't blow up from being on a 15 amp circuit, your visor would have been just fine as long as the voltage was within the allowable range of what the visor can handle.
