Re: What next? Starter?

Not sure what car you have But:

You could measure the voltage at the terminals on the starter. That would be the car chassis ground and the output of the starter relay.

Using a piece of wire with a couple of alligator clips you can activate the relay and check the voltage with a decent meter.

Expect this to crank the engine so watch the rotating parts.

It shouldn't drop below 5.5 volts with the starter under load.

This would tell you if your cables are good and the connections between the battery and the frame and the engine are good.

If this is a 6 Volt car it needs heavy battery cables and I don't think anybody still sells ready-made.

If the battery cables are too light it may crank slowly and the voltage drop may be too great to fire the coil.

My car has the feed to the ignition switch connected to the starter relay on the same post the battery cable lands.
