Bayou getting no spark

[Colby Vittorio]

I have had a bayou 220 for 3 year and this past year we let a good friend  borrow  it and while he had it the battery  went to crap so i got a new one hooked it up and no light no starter nothing working my first thoght cylonod or cdi box so i looked up how to check if cdi box is bad and it told me to take out my plug and see if there was spark so i did and no spark so i have no clue ps changed the fuse also

Sounds to me like power isn't getting from the battery anywhere if that light doesn't come on when you turn the key. I would check the battery connections, ground, and all the main fuses.

double check all wiring connections they are known to get corrosion

Check the ignition switch and the plugs going to it. 

Get familiar with a multi meter and the continuity settings to see what’s working/not.  The tester is also good to check voltage.   

Start going through the wiring in sections.  See what has voltage and keep moving from there.
