Snapper 1650 Series User Manual

ALTERNATOR CHARGING SYSTEM
PRECAUTIONS:
1. Do not connect battery to cables in
wrong polarity. This will cause regulator-rec¬
tifier damage.
2. Break continuity between regulator-rec¬
tifier unit and battery when using a remote
charger on battery or when jumping from
another battery. This will eliminate damage
to regulator-rectifier if polarity is reversed.
3. Disconnect wiring harness at regulator-
rectifier before using arc welder equipment.
PRE-SERVICE CHECKS
1. Check for good ground between regula¬
tor-rectifier and mounting.
2. Check for poor connections or broken
wires.
TROUBLESHOOTING
BATTERY CHARGING AT HIGH RATE:
1. Connect DC Voltmeter across battery. If
voltage is over 14.7 volts, regulator-rectifier
is not functioning. If voltage is under 14.7
volts, battery is defective.
BATTERY NOT FULLY CHARGED:
1. Connect a jumper wire from battery
positive terminal to coil positive terminal.
2. Start engine and disconnect B plus wire
from circuit breaker (wire going to solenoid)

3. C onnect DC Voltmeter positive lead to
wire removed from circuit breaker terminal
and negative lead to ground. Run engine at
full speed and check DC Voltage. Disconnect
jumper wire to coil after test is completed.
Volt meter reads:
a. Above 14 volts.
Check alternator. OK
ammeter may be de¬
fective.
b. Less than 14
volts but above
"0" volts.
Defective regulator-
rectifier.
c. "0” voltage.
Defective Stator or
regulator-rectifier.
4. Reconnect circuit breaker. Start engine
and check voltage across battery. If reading
is 13.8 volts or more, place a load on battery
to reduce voltage to below 13.6 volts. This
can be done by turning on lights for a short
time.
a. Charging rate
increases.
Alternator OK.
b. Charging rate
does not
increase.
Defective stator or
regulator-rectifier.
5. A check to determine if stator or regu¬
lator-rectifier is defective, unplug ac leads at
regulator-rectifier and connect voltmeter
leads in spade connector. Check voltage with
engine running at full speed.
a. Less than 20
volts.
Defective Stator.
b. More than 20
Defective regulator-
volts.
