need an ohm meter.

primary coil checking, set meter to ohms, put red wire on mount bracket of coil, neg black wire to small wire from coil (not wire for plug). should read 0.36-0.48 for 2001 warrior.

check secondary ohm, again, red wire to spark plug cap, black wire to wire from coil, reading should be 5.44-7.36

have you tried another cdi, pretty common with yamaha warriors.
