Starter issue
Getting single click...more over an intermittent single click; sometimes starts right away, sometimes half a dozen or so turns of the ignition switch. Metered all the wires from starter to battery, starter to ground, battery to ground, disconnected, cleaned, reconnected wires, changed starter relay, jumped starter relay, new battery, new starter and solenoid...NOTHING helped.
What am I missing?

Car Is Not Cranky . . . . SO I AM !!!!!!
Use a spare headlight (because it puts a load on the circuit) and connect it across the M terminal of the starter and ground.
(Use a real headlight, not a LED sled, not HID’s meant to help the Mr. Magoos squint out to see where they’re going.)
Connect a voltmeter across the M terminal of the starter and battery ▬.
Make the leads long enuff to take the voltmeter into the cockpit.
Under normal circumstances, when cranking you will see about 9 volts on the meter.
On the occasions the starter fails to crank note the voltage.
The voltage will tell you what direction to turn.
If it’s about 12 while you are trying to crank, but the starter is not turning - the problem is in the starter.
If it’s under 8 while trying to crank - the problem is excessive resistance in the starting circuit.
Therefore if it is in the starting circuit you can move the probe you applied to terminal M at the starter, to the positive terminals at the solenoid, then keep moving up the line till the problem shows itself VIA increased voltage.

Re: Starter issue
Never underestimate the obvious AND basic....found the fault after removing and thoroughly cleaning the mating surfaces of the starter and engine. OPS CHECK GOOD.
