1.4 Inspection of chassis ground
• A special ground bolt is used to tighten a ground terminal. When
servicing the ground point, be sure to follow the procedures de-
scribed below:
• When reinstalling the ground bolt
Tighten the ground bolt to the specified torque.
• When relocating the ground point
A special ground bolt must be used. Spot-weld a nut to a
frame and tighten the ground bolt to the specified torque. Be
sure to apply touch-up paint to the welded point.
2. Service Precautions for Alternators
• When servicing alternators, observe the following precautions:
• Never reverse the polarity of battery connections.
If the polarity of the battery connections were to be reversed,
a large current would flow from the battery to the alternator,
damaging the diodes and regulator.
• Never disconnect the battery cables with the engine running.
Disconnection of the battery cables during engine operation
would cause a surge voltage, leading to deterioration of the di-
odes and regulator.
• Never perform inspections using a high-voltage multimeter.
The use of a high-voltage multimeter could damage the diodes
and regulator.
