The starter solenoid is a fairly simple mechanism that transmits electrical current from the battery to the starter. When you turn the key, the solenoid engages, using the electrical motor in the starter to get your engine running. If the solenoid is not functioning properly, the vehicle may not start. Determining whether the issue is the starter solenoid, the battery or the starter itself can save you time and money when repairing it yourself and seeking to have the repair work done. Start by locating the starter and work to narrow down the cause of the issue.

How To Test a Starter Relay
when i turn the ignition switch all i hear is a click from the solenoid. It’s a brand new starter-solenoid. I checked if the engine has seized and it has not. I had the battery re-charged and checked at a local parts store and it’s good. It’s strong enough to start the motor.
Checking the solenoid
Modern cars have a pre-engaged starter, which has the solenoid mounted on the casing. Many older cars have an inertia starter, which has a separate solenoid mounted elsewhere in the engine compartment.
The last arrow you need in your electrical diagnosis quiver is the voltage drop measurement. It’s used to help diagnose high-resistance failures. People sometimes talk about the voltage drop measurement in hushed reverent tones, as if it is the key to all electrical diagnosis, and by knowing it you’re inducted into the Illuminati. It’s not that big of a deal. It certainly isn’t a panacea to all electrical problems. But every once in a while, it is handy.
Pretest Considerations: If possible, visually inspect the starter and-or interview pilots or operators for starting history. Indications of long cranking periods, burning odor or smoke from the starter, kickbacks, a cracked starter mount, a fast spinning starter with no prop movement, oil in starter, grinding noise, or a damaged ring gear are generally indications that the starter is in need of repair and the following tests will not be helpful. Jump to starter issues below for some guidance, but chances are you will need to replace or overhaul your starter.
Starter motors are a common component in the majority of cars and their main function is to help start the engine. Due to this key role in the ignition process, if the starter motor breaks then it’s unlikely you’ll be able to operate the vehicle.
Common Starting Issues in Trucking Applications
So you think your starter motor is on the blink (again!), and with a full truck you’re sitting idle by the side of the highway halfway between where you came from and where you want to be, with a deadline looming and a crusty and inconsiderate client. And you’re cursing why your repairer can’t put a decent starter in your rig instead of the obvious Chinese-American-European piece of junk he’s used.
