    Van truck making clicking sounds and won't start

    after I shut my truck off and tried to start it up again it wouldn't start it was making clicking sounds. I thought it was the battery so I charged the battery up, put it back on the truck and turned the ignition on the nothing to same clicking noise. The clicking is coming from over by the ceilinoyed switch. I changed that out and still the same thing I think it maybe the starter i'm not sure

    could be a flat spot on the starter. could be a bad solonoid (but not likely). could be bad connections to the starter/solonoid from the batteries.
    I can't think of anything else.

    check the ground cable (bout an inch in diameter) to the starter, had same symptoms in a volvo daycab.

    the starter solenoid is piggybacked on the starter. The starter relay is on the firewall.

    Starter testing on engine. I assume the starter is a 12volt Delco 40MT, 42MT, or 50MT.
    Battery positive on large stud on top of the solenoid.
    Battery negative on the large stud on the rear of the starter. Also earth wire from here to a small stud on the solenoid.
    Starter energising wire on another small stud on the solenoid. This wire goes to a starter slave relay, usually nearby on the chassis or firewall etc. This relay has a positive cable on its other stud. The start button operates this relay which closes its contacts and powers up the energising wire to the main starter solenoid. The starter will then crank the engine.

    To test the system connect a voltmeter to the main positive and negative studs on the starter. Voltmeter should read at least 12volts.
    Press the start button and see if the voltage drops. If the starter doesn't work, but the voltage drops substantially you have problems in the main battery cables, isolation switch, or batteries.
    If the voltage doesn't drop by much, move the positive voltmeter lead to the solenoid energising wire.
    Press the start button again.
    If the voltmeter reads about 12volts with the start button pressed, the starter is faulty.
    If the voltmeter doesn't show any voltage it means that the relay is not working. This could be a faulty relay or wiring to it from the start button.

    Check for dirty connections on the copper link from the solenoid output stud to the starter fields. I have also seen this link break on Cummins engines.

    Could be anything between the alternator and starter. You've replaced the starter and batts, the grounds could be corroded, the positive or negative wires on the batts can be corroded, the wires to the starter or the ground cables could be corroded, the ground from the motor or trans to the batts could be corroded. Or the motor could be locked up. Have you been losing coolant?

    You're not trying to start it in gear, are you? (It's common).

    You need to change the firewall solenoid.
