As it's no start then first thing to get checked
is starter. The battery to starter connection. If the battery to starter
connection is got loose then this will not let the engine to start. First check
the battery to starter connection. If the connection checked out ok, then check
the voltage to the starter terminals, If its working then it will show 12 volts,
If its faulty then starter has to be replaced. But if the starter is checked
out ok. Then yes the fusible link needs to be checked.
1) The charging system is protected by a 12 gauge fusible link
located in the A11 circuit.
2)
This fusible link is between the
alternator/generator and the starter.
3)
The generator ground is provided
through a case ground in the generator to its attaching bracket.
4)
This generator uses a voltage regulator
internal to the Power train Control Module (PCM) .when the vehicle is running; battery
voltage is applied to the generator field terminal through the A142 circuit.
5)
This circuit
is the output from the contact side of the Automatic Shut down (ASD) relay. The
ground, or voltage regulated side, of the generator field is controlled by the
K20 circuit which connects to cavity 4 of the PCM connector.
6)
When there is current present in the
field, and the rotor is turning, the stator in the generator produces a B+
voltage that is supplied to the battery through the A11 and A0 circuits. The A11
circuit is connected to the output terminal of the generator and connects to
the engine starter motor battery feed terminal.
7)
The A0 circuit is a direct feed line
from the battery and connects to the engine starter motor. Grounding for
the system is accomplished at the battery negative terminal. These grounds
connect to the engine and body.
Tip: --- Inspect for a
blown fusible link in the A11 circuit between the generator and
the starter motor. Get this checked. But if all checked out ok then the
park neutral switch has to be rechecked, if its faulty then it has to be
replaced. Check the voltage to the battery, it should show 12 volts. If it's
low then this is due to low battery voltage.
