Where does the power come from on a starter solenoid?
The power on the small wire at the starter solenoid comes from the key switch, and may or may not go through one or more security systems. First, you can verify that you have battery voltage going IN to the key switch. If not, it’s a fuse or wiring causing the voltage drop.
Which is low voltage, the voltage to operate the solenoid?
Which voltage is low, the voltage to operate the solenoid or the voltage on the large wire that actually runs the starter? To see if its a bad ground, just check your +12v to multiple grounds. If you check the +12v to many different grounds and keep getting 9.5v then the incoming 12v has a bad connection or something somewhere.
How can I tell if my starter solenoid is bad?
To see if its a bad ground, just check your +12v to multiple grounds. If you check the +12v to many different grounds and keep getting 9.5v then the incoming 12v has a bad connection or something somewhere.
What should the voltage drop be on a starter?
STEP 3: Perform a voltage drop test on the starter main cables. The starter voltage drop should be less than .5 volts drop total on the cranking circuit. This is an important step and often the cause of a slow crank complaint.

How to diagnose a cranking starter problem?
While cranking problems can be frustrating, identifying and correcting the root cause does not have to be. The first step is to identify the symptoms. In a cranking system, you can divide your symptoms into one of three possible troubleshooting categories: Slow Crank: The starter will crank, however, the engine RPM is slow to start the vehicle.

What kind of battery do you need for a solenoid switch?
2 thicker and bigger connectors for the high current switch Assuming that you are going to perform this wiring in a car, you are probably going to use a 12V battery. By convention, it’s advised that you use black wire for negative and red wires for positive.
How many control wires does a solenoid have?
There are 2 control wires (brown/red & black/orange). Does it matter what wire goes to which control pole? And does it matter what pole of the solenoid I put the battery cable and what pole I put the battery output on?

Why do I have low voltage at my starter solenoid?
Those things get a signal from a cell phone tower and turn the starter off. That relay could cause your voltage drop as well. If you find one of those, remove it regardless of it’s condition! And last but not least, the terminal at the solenoid. By the time you get down there, you are going to have found your problem.
