I have a 91 yamaha blaster, does anyone know how to put a 12 volt battery in it.?

Question

i would like to charge and use it with the electrical system.

Answer 1

You need to buy a big flashlight and strap it on the handlebars.  You don't want to try and create or modify the electrical system of a Blaster.

Answer 2

You cant put a12v battery on a Blaster.  There is no such charging system for it on a quad.  Even if there is one, where are you going to mount the battery? on the rear rack? The battery probably weights as much as you. I dont know what you are trying to achieve, but i am a little curious.

Ok I think I see what you are trying to do, you want more light so you can see better at night.  If that's the case, then you should start with the stater, get it rewrap to put out more amperage.  Hope that will help.
