which wire is positive and negative? how can you tell or check?

 

I have a little tool with a light for negative and one for positive. It wasn't expensive and I use it all the time. It's easier then pulling out the multimeter everytime.

What type of hand warmers are you going to get. I got the ones that go under your existing grips. I used compressed air to take off the factory grips. Worked like a charm. Took a matter of seconds and this way I didn't have to buy new grips.
