The previous "backwoods" way to test an alternator was to start out the vehicle, then disconnect on the list of battery terminals and find out if the vehicle retains running. Though this does get the job done, it isn't proposed.

Most alternators are created of two aluminum shells with the stator assembly "sandwiched" in between.

Truly the one other elements that may be lousy can be the rotor and stator. These can idiot your ohmmeter exam, since the resistance concerning The three wires in the stator along with the two slip rings within the rotor is quite near to zero. There can be a short in between coils, plus the looking at would even be zero. If every little thing exams fantastic so you are self-confident inside your "negative alternator" diagnosis, you may want to dump many of the areas back again within and bolt the point back again collectively, then Visit the parts residence and obtain a rebuilt.
