Question about 1983 Chevrolet Chevy
It is most likely some interruption from the battery to the starter solenoid. If it an auto shift make sure the selector is in 'park' or 'neutral'. First check that your battery is charged and that it is in a healthy state. Make sure the battery terminals are clean and bright and that the battery strap mounts are in a similar good condition. When fully charged the battery should have 12.5 volts across the terminals. Next switch on your main beam headlights. They should be bright with no appreciable dimming over three minutes. If you are happy with the battery condition the next thing is to attached an insulated wire to the starter solenoid power terminal. Run this wire to the positive terminal of the battery and when you make contact the solenoid should be heard to click and clonk as is pushes the armature of the motor onto the flywheel rim. If you are satisfied that this is OK remove this 'jumper' wire and check the heavy duty leads to the starter motor proper. Now check the earth strap back from the engine block to the frame, corrosion of the bolt contacts here can severely disrupt current flow. The start sequence is as follows: Battery supplies power to the ignition switch. Turning the switch to 'ignition' sends current through the transmission isolator switch (if automatic - to prevent starting while in gear hence the need for park or neutral to be selected). The current then passes through the starter fuse...check this for continuity! From the fuse the current goes to the starter solenoid. The solenoid engages and the armature is thrown forward to make contact with the flywheel rim. Simultaneously, the armature movement bridges the heavy duty electrical contacts within the motor to allow heavy current to be drawn by the starter motor to kick the flywheel over. Return current to the battery passes through the engine block to the earth strap to the frame of the vehicle. Check the final strap cable from the frame back to the negative terminal of the battery. Very occasionally the switching mechanism at the back of the ignition switch can fail, a wire breaks or a contact becomes worn or dirty.
