12/15/25 Amp Battery Charging Systems

NOTE: Always zero ohmmeter on each scale before testing to ensure accurate readings. Voltage tests should be

made with engine running at 3600 RPM with no load. Battery must be good and fully charged.

When problems occur in keeping battery charged or battery charges at high rate, charging system or battery might be

causing problems.

To test charging system for no charge to battery:

1. Insert an ammeter in B+ lead from rectifi er-regulator.

terminals) on battery to reduce voltage. Observe

ammeter.

Condition Conclusion

Charge rate increases

when load is applied.

Charging system is OK

and battery was fully

charged.

Charge rate does not

increase when load is

applied.

Test stator and rectifi er-

regulator (steps 2 and 3).

2. Remove connector from rectifi er-regulator. With

volts.

Test stator further using an

ohmmeter (steps 3 and 4).

3. With engine stopped, measure resistance across

stator leads using an ohmmeter.

Condition Conclusion

Resistance is 0.064/0.2

ohms.

Stator is OK.

Resistance is 0 ohms. Stator is shorted; replace.

Resistance is infi nity

ohms.

Stator is open; replace.

measured.

ground; replace.

To test charging system for battery continuously charging

at high rate:

1. With engine running at 3600 RPM, measure voltage

from B+ lead to ground using a DC voltmeter.
