One way to check the CDI on an alternator is to use an ohmmeter. If you do not know how to use an ohmmeter, you may be better off by taking your vehicle to a repair shop to look at the alternator.
can Hysteresis motor use like alternator
yes
Use a large wrench to take tension off of your serpentine belt and remove the belt from the alternator, (just the alternator). Disconnect the wires. Remove the bolts then the alternator. Put new alternator in place using old bolts. Replace wires (may only be one wire, depending on the alternator). Get your large wrench back out, put the belt back on the alternator, and your good to go.
Not that hard. Worst part is installing the alternator in the mount. I used a fiberglass mallet to tap the alternator case in place and line up the bolts. 1) remove negative battery cable 2) loosen the clamp and remove the air intake hose 3) use 5/8" wrench to move the tension pulley and remove the belt from alternator 4) unplug wire and use 10 mm wrench to remove red wire from alternator 5) remove alternator bolts 6) use pry bar and remove alternator 7) install alternator and tap case with mallet 8) reverse above dirrections
