7. If the regulator/rectifier fails any one of these tests, replace it with a new one.
8. Check the D.C. amperage output of the regulator/rec-
tifier using an Ammeter of sufficient capacity or a
D.C. Shunt tool and a volt meter set to read on the
millivolt scale, as described in the TOOLS section of
this chapter.
9. If the regulator/rectifier passes all of these tests, but
the battery is not charging, check the circuit between
the regulator/rectifier D.C. output (B+) terminal and
the battery positive post for voltage for a voltage
drop. See Figure 7.32.
• The harness connector, the 30A fuse, and the hot
post on the starter solenoid all lie between the reg-
ulator/rectifier and the battery.
