The starter solenoid would click and engage but the starter wouldn't turn over the engine. In this video I build a new contact from a copper pipe and install it into my starter to fix the issue. How to make and replace a solenoid contact to repair a starter that isn't working. The solenoid contacts are a wear part that will need replacing from time to time.

"The starter solenoid works as a powerful electric relay. When activated, through the control terminal, the solenoid closes the hi-current electric circuit and sends the battery power to the starter motor. At the same time, the starter solenoid pushes the starter gear forward to mesh with the ring gear of the engine flexplate or flywheel."

"Have you noticed your starter turning slower and slower, or worse yet, you turn the key and all you get it a loud click and a slight (or no) dimming of the lights? If you answered yes to any of the above questions, your starter may be due for some R&R. My 22R-E equipped 1985 4Runner, had over 210,000 miles on it, and I'll bet the starter is bone stock. The starter is actually composed of two main parts, the series-wound starter motor itself and a solenoid which serves dual functions of pushing the drive gear into the flywheel as well as making a high-current contact to supply battery power directly to the motor. Starters can pull many hundreds of amps of current under load and the solenoid acts like a giant relay taking the low current signal from the ignition switch to control the high current for the motor.
The solenoid consists of a steel plunger that is pulled into an electro-magnetic coil, that is energized by the ignition switch. There is a rod extending from the plunger that actuates the starter gear and a spring on it to retract the gear after the engine starts. Also, at the other end of the plunger is a copper ring that makes contact with two copper contacts, one from the battery and the other that goes to the starter motor itself. When the plunger is pulled into the coil, the copper ring completes the circuit between the two contacts, current flows and the starter motor spins, driving the small gear which in turn spins the flywheel, making the engine turn over. Over time, the two contacts are eroded by the inductive arcing that occurs when the starter motor is started and stopped. In every case I have heard of, only the contact on the battery side of the solenoid wears out."
