AC VOLTAGE OUTPUT CHECK v
1. Insert RED test lead into v receptacle in
meter.
2. Insert BLACK test lead into
COM
receptacle in
meter.
3. Rotate selector to position.
4. Attach RED test clip to alternator AC output
terminal(s).
5. Attach BLACK test clip to engine ground.
NOTE: When checking AC voltage output of stator
on 10-16 and 20 amp regulated or Quad-
Circuit alternator systems, attach one
meter test clip to each output pin terminal
in YELLOW connector from stator. Test clip
leads may be attached to either output pin.
6. With engine running at 3600 RPM, AC output
reading should be close to specification listed for
alternator type in Table 2.
