The 12 volt - 37 Amp Automotive type Alternator is<br />
optionally available in place of the Flywheel Alternator.<br />
No maintenance or adjustments are required other than<br />
periodically checking for loose, broken or dirty wireterminal<br />
connections, and for proper drive belt tension.<br />
Bearings are pre-lubricated, no additional lubrication is<br />
necessary. The Regulator is an all electronic transistorized<br />
devise, therefore no mechanical contacts or relay adjustments<br />
are necessary for voltage regulation.<br />
The alternator is wired into the engine electrical system per<br />
Fig. 47.<br />
IMPORTANT<br />
This is a Negative Ground system. Charging components<br />
will be damaged if grounded wrong in connecting or<br />
jumping batteries.<br />

If light indication is other than shown, stator is defective. If<br />
stator checks out good, perform voltage test 7.3.<br />
Test 7.3 STATOR RUNNING VOLTAGE<br />
With the engine stopped, unplug all connectors between<br />
modules and stator. Start the engine and run at operating<br />
speed. Perform the following tests with an AC voltmeter:<br />

Cbaution: Handle battery carefully to prevent acid<br />
urns. Avoid sparks near battery - gas given off by<br />
battery is explosive.<br />
PRECAUTIONS to be exercised in the use of belt driven<br />
alternator:<br />
1. Observe proper polarity when installing battery;<br />
negative battery terminal must be<br />
grounded. Reverse polarity will destroy the<br />
rectifier diodes in alternator.<br />
2. As a precautionary measure, disconnect<br />
ground battery terminal when charging battery<br />
in vehicle. Connecting charger in reverse will<br />
destroy the rectifier diodes in the alternator.<br />
3. DO Not, under any circumstances, short the<br />
field terminal of the alternator to ground, as<br />
permanent damage to the regulator may occur.<br />
4. DO Not, remove the alternator from the vehicle<br />
without first disconnecting the grounded battery<br />
cable.<br />
5. Do Not, operate engine with battery disconnected,<br />
or disconnecthe alternator output lead<br />
while the alternator is operating, as damping<br />
effect of the battery will be lost. The voltage<br />
will rise to an extreme value and permanent<br />
damage to the regulator may occur.<br />
6. DO Not, disconnect the voltage regulator<br />
while the alternator is operating, because the<br />
large voltage transient that occurs when disconnection<br />
takes place may damage the regulator.<br />
7. Caution: Output wires from Alternator to<br />
Ammeter, and from Ammeter to battery terminal<br />
on starting solenoid must be of sufficient<br />
size for charging 37 amps. Use No. 10 gage<br />
stranded wire, or larger.<br />
