[9-6.] Electrical equipment
1) Checking of the warning lamps on the instrument panel. Check the "ON" and "OFF"
function of the warning lamps before every operation.
2) Checking and maintenance of the battery.
Proper battery maintenance is vital for dependable service.
2-a)
Keep battery clean by wiping it with a damp cloth.
Keep all connections clean and tight. Remove any corrosion, and wash terminals with a
solution of baking soda and water.
2-b)
Keep battery fully charged, especially during cold weather. If a battery charger is needed,
charge it after disconnecting battery cables from battery.
2-c)
Check level of electrolyte in each cell at least every 200 hours. If low, fill to bottom of filler
neck with distilled water.
2-d)
To check battery condition, use a battery hydrometer. Check specific gravity of electrolyte in
each cell. Charge battery if reading is below 1.215.
Caution
Keep all sparks and flames away from batteries, to avoid sparks, connect
earth cable last and disconnect it first.
Important
Do not add distilled water in freezing weather unless engine is run at least 30
minutes to ensure thorough mixing.
3) Checking and adjustment of the alternator (electric
generator) V-belt tension.
If the tension for the V-belt is too tight the V-belt may
be easily damaged. On the other hand, if the tension is
too loose, slippage results and makes it hard to generate
electricity.
3-a)
Checking the tension.
With the engine stopped, press belt midway between
pulleys and measure the "give".
Belt should give 10 mm with about 10 kg force.
