Jump Starting Procedure - Isuzu NHR 4J Series Workshop Manual

6D1 – 6 ENGINE ELECTRICAL

JUMP STARTING PROCEDURE

1. Set the vehicle parking brake.
If the vehicle is equipped with an automatic
transmission, place the selector lever in the "PARK"
position.
If the vehicle is equipped with a manual transmission
place the shift lever in the "NEUTRAL" position.
Turn "OFF" the ignition.
Turn "OFF" all lights and any other accessory requiring
electrical power.
2. Look at the built-in hydrometer.
If the indication area of the built-in hydrometer is
completely clear, do not try to jump start.
3. Attach the other end of the same cable to the positive
terminal of the discharged battery.
Attach the end of one jumper cable to the positive
terminal of the booster battery.
Do not allow the vehicles to touch each other.
This will cause a ground connection, effectively
neutralizing the charging procedure.
Be sure that the booster battery has a 12 volt rating.
4. Attach one end of the remaining cable to the negative
terminal of the booster battery.
Attach the other end of the same cable to a solid
engine ground (such as the A/C compressor bracket
or the generator mounting bracket) of the vehicle with
the discharged battery.
This ground connection must be at least 450 mm (18
in) from the battery of the vehicle whose battery is
being charged.
