3. Storage
If the motorcycle! is not to be used for a long
time, remove the battery and have it stored.
The following instructions should be ob-
served by shops equipped with charger.
1. Recharge the battery once a month.
2. Store the batte ry in a cool, and dry place.
3. Recharge the] battery before reinstalla-
tion.

A. Lighting Test^ and Checks — A.C.
Circuit
1. A.C. Circuit Oiitput Test
With all A.C. lights in operation the
circuit will be balanced and the voltage
will be the sarrjie at all points at a given
r/min.
Switch Pocket Tester to "AC20V" posi-
tion.
Connect positive ( + ) test lead to blue
Connection and negative ( —) test lead
to a good ground.
Start engine, tuirn on lights and check
y/oltage at each engine speed.
If measured vo tage is too high or too
low, check for pad connections, dam-
aged wires, burned out bulbs or bulb
capacities that are too large throughout
the A.C. lighting circuit.

NOTE:
This voltage test can be made at any point
throughout the A.C. lighting circuit and the
readings should be the same as specified
above.
2. Lighting Coil Resistance Check
If voltage is incorrect in A.C. lighting cir-
cuit, check the resistance of the yellow
wire windings of the lighting coil.
a. Switch Pocket Tester to "R x 1 " posi-
tion and zero meter.
b. Connect positive ( + ) test lead to blue
wire from magneto and negative ( —)
test lead to good ground on engine.
Read the resistance on ohms scale.
Connect magneto and negative ( —) test
lead to a good ground on engine. Read
the resistance on ohms scale.
