CHARGING & STARTING SYSTEM
Page 2B-6 90-857046R1 NOVEMBER 2001
Alternator System Test
6 Ampere Stator
CAUTION
When testing any charging system, the technician must use an ammeter capable
of reading the maximum current output for the test being performed or higher. Fail-
ure to use a amp meter that can handle the specific current load could possibly
damage the meter being used.
IMPORTANT: Rectifier (optional accessory) must be functioning properly for accu-
rate test results to be obtained.
1. Remove RED lead from (+) terminal of rectifier.
2. Connect RED (+) ammeter lead to rectifier (+) terminal and BLACK (–) ammeter lead
to RED rectifier lead.
3. With engine running at the indicated RPM, the ammeter should indicate the following
approximate amperes:
0
1
2
3
4
5
6
7
8
0123456
RPM x 1000
Alternator Current (Amps)
4. If proper ampere readings are not obtained, replace stator.
