Before I contemplate pulling the car apart three days before Race Retro I thought I'd throw this one out there for consideration!

The battery is 2015 vintage, been sitting for 3 months. I jump in the car, put the kill switch key in, turn the ignition on, press the start button and it fires up just fine. Take the car out for a drive 6 miles or longer and get it warm and turn it off. It won't restart, pressing the start button merely results in the voltmeter showing a big deflection down. Wait an hour or two and it cools down. Press start and off we go again.

I think the battery is fine, beginning to suspect the starter motor.

Any thoughts peeps?

Cheers
Guy
