Electrical System

7. If the regulator/rectifier fails any one of these tests, replace it with a new one.

8. Check the DC amperage output of the regulator/recti-

fier using a an Ammeter of sufficient capacity or a DC

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 DC output (B+) terminal and the

battery positive post for a voltage drop.

See Figure 7.23.

• The harness connector, the 20A fuse, and the hot

post on the starter solenoid all lie between the reg-

ulator/rectifier and the battery.
