king quad 300 cdi box

I have a 2000 king quad 300 and im not getting any spark is there a way to test the cdi box or coil to see if good,or does any one have any other suggestions what it may be . thanks for your time and any info you can give would be highly apprecaited on my behalf.......

I would test the Coil first and check all fuses. Easiest way to check the coil is the replace it with a new one. You can test it with a test light I beleive to make sure it has power getting to the plug, but i have never tried it

thanks ill have to give that a try , i am buying a new kq befor winter but was going to give old one to son for hes getting to big for his 110cc so i hope to be able to fix for him
