Why does my old car battery not crank?
If the vehicle will not crank when the battery is known to be good, we won’t have to backtrack and check it again. When it comes to vintage cars and batteries the biggest problem is when unexpected long-term storage occurs. Sometimes we park our classics expecting to use them in the near future.
What does no crank no start car mean?
Mechanics refer to this as a no crank no start condition. Of course, the number one reason for an engine not the crank on any car would be a problem with the battery. Since classic car owners are familiar with how to treat a battery during long-term storage we’ll just touch on this briefly and then move on.
Why does my van battery not turn over?
It may only be some black residue between a lug on a cable and the washer or nut clamping on it. Another way to test each connection with the battery connected is to use the volt meter to measure on either side of any given connection. If there is corrosion/resistance you will see a voltage on the meter.

What to do if your car has no crank?
In this situation, it’s recommended to replace the battery and the cables so we know our cranking voltage will be adequate. Although the battery and the starter motor are often the root cause of a no crank condition, many classic cars have a few separate components between these two devices.
Why does my no crank no start car not start?
Inside the relay, a set of electrical contacts allows current to flow to the starter solenoid. If these contacts become corroded or extremely worn, they may not get the job done. An external starter solenoid, unlike the relay, carries high voltages.
