Rapid Clicking When Starting
Hello,
Yesterday we went to turn over the 1969 Mustang. It was cranking fine and then out of nowhere it started rapidly clicking from the starter solenoid. My first thought was a bad starter solenoid (Even though it was newer) went out. I replaced it and nothing changed. The battery is above 12 volts and has the charger on it to help rule it out. Could the starter be shot? I hit with a hammer and nothing changed it. The starter is new as well but I haven't had good luck with CJ Pony Parts using them as replacement parts.
Thanks!

Its probably getting a bunch of voltage sag due to low current and/or high resistance.
You put the meter on the battery when its sitting there doing nothing and its all sun shine and bunnies at 12v but when you ask 3 to 5 hundred amps from it the voltage maybe dropping well below 10v.
High resistance can cause this in the form of: 1) Dirty and corroded terminals 2) Loose terminals at battery or solenoid or engine block 3) corroded or broken / partly broken heavy battery wires 4) Failure of the battery terminal crimp on the wire. plus other reasons I cant think of that are similar to the above.
Failure of battery can cause this in the forum of: 1) reduced capacity because of worn or eroded plates (end of life), 2) internal short 3) low acid / water levels
Check those things first
