Hi, First time posting, so be gentle

Can anyone tell me what output should be coming from a TDCI "smart" alternator when disconnected ie - out of the car, mine is showing only .8 volts, but am not sure if this is happening because its not plugged in, I tested it by connecting a drill and spinning it to 3500rpm so speed should be fast enough. Any help would be greatly appreciated before I buy a new one if not needed. Thanks, Jamie.

 

Anyone have a reading on this???

 

You should be testing it with a battery connected to B+ and the housing of the alternator, it won't do anything without a battery. Then if your drill is powerfull enough you should see 14 volt. The plug doesn't need to be connected.

 

should have tested it on the car with the 3 pin plug disconnected will give 14 volts 50 amps this is the default setting
