1987 SUZUKI GRAND VITARA alternator

Brush and Brush holder
Check each brush for wear by measuring its
length as shown. If brush is found worn down to
service limit, replace brush with holder.

Rectifier
Using an ohmmeter, check continuity between
“B” terminal and ground.
Put one tester lead to terminal “B” and the
other lead to ground; then swap two leads. Of
two tester indications, one should be about
10 ohms, meaning continuity, and the other
should be infinity (non continuity).
If not, replace rectifier assembly.
Condenser
Check condenser capacity in regulator.

ASSEMBLY
Reverse disassembly procedure, using care on
following points.
1) Use a press when forcing bearing into rotor
shaft or drive end frame.

GENERAL DESCRIPTION
The battery has three major functions in the
electrical system. First, it is a source of electrical
energy for cranking the engine. Second it acts as
a voltage stabilizer for the electrical system. And
third, it can, for a limited time, provide energy
when the electrical load exceeds the output of
the generator.
Each new car shipped from the factory is
fitted with following battery.

This battery is completely sealed, except for six
small vent holes in the top. These vent holes
allows the small amount of gas produced in the
battery to escape. This sealed battery has a
built-in temperature compensated indicator in
the top of the battery.

CARE OF THE BATTERY
[Electrolyte freezing]
The freezing point of electrolyte depends on its
specific gravity. Since freezing may ruin a
battery, it should be protected against freezing
by keeping it in a fully charged condition.

21-15. WIRING HARNESS ROUTING
When reinstalling wire harness, be careful for the following.
l When doing wiring harness related work, make always sure to disconnect battery negative cable from
battery.
l Clamp wire harness securely at prescribed positions.
l Try to route wire harness so as to avoid contact with other parts as much as possible. Use special care
not to let it contact sharp edges of body or other parts.
0 Connect connectors securely.
