15 Oct How to Check on Your Trucks Starting System

If you go to start your truck and all you hear is a click or nothing at all, there are a few things that you can check on your starting system. Find your starter relay, then take your multimeter and find the battery side of the relay make sure the voltage is at least 12 volts, if it isn’t, check all the connections, clean and tighten as needed. If voltage is still low charge and load test the batteries.

Once you have good voltage at the battery side of the starter relay, put the meter on the starter side of the relay and hit the starter button, if there is no voltage on the starter side, check the starter button wire on the relay with the meter with the button pushed, if there’s power then replace the relay, if not you have a broken wire between the relay and the starter button.

If you have power on the starter side of the relay, go to the “S” terminal on the starter solenoid to check for power when the button is pushed, if there’s no power you have a broken wire or a broken link from the relay to the starter. If there’s power to the starter solenoid “S” terminal and the voltage is good and the connections are clean and tight, then replace the starter.
