Alternator not charging

Post 11!!^^

But in addition, test for an open from battery to alternator output

Hook up as above, and with the jumper connections made, slowly bring up RPM and see if battery voltage rises

If not, move your meter to the alternator "big stud" (output stud) and see if that voltage rises and if so, to a high level. If it does, then you have a bad connection in the circuit from output to battery

If neither meter connection shows a rise, attempt to determine if the field is actually drawing current. With the engine off, and "in the shade" preferably darker, hook/ unhook your connections to the field. You should be able to see a small spark every time you connect the jumper.
