alternator repair - An OverviewUsing an ohmmeter, exam the diodes, the two regulator diodes (triode in Delcotron) and rectifier diodes. A diode is a "one way valve" for electric power, so Every single diode should really exhibit some resistance looking at around the meter A method, and no reading, or infinite resistance one other way. A foul diode will either have infinite resistance both of those means, or will perform some present (show a reading through around the meter) equally ways.
Here is A further shot with the socket from Yet another angle. You can just make out the socket and extension.
They need to be in a couple tenths of the volt of one another. If not, there may be too much resistance during the circuit. Numerous motor vehicles Have a very fusible connection or a substantial fuse to protect the alternator. These may be burned up by a brief or improper usage of jumper cables. If there is not any electricity for the alternator B+ (large output terminal) then a nasty fusible link or maxi-fuse might be the problem.
