ELECTRICAL PROBLEM HELP

[POORCARDEALER]

1960s Saloon

Starts first click of key when cold, no issues...leave running 5 minutes, turn off...when trying to restart there is nothing, I get ignition lights on dash but no clicking or trying to start, zilch....was sure it was a starter selenoid fault, swopped for a new one but the same. If i go back to it in an hour it will start.

Any ideas, driving me mad

Thanks for the replies so far.

Car Humber Snipe

2.2 engine

Deffo not the battery

No button to press on the new part....if I power the starter directly it works

Will spend a bit more time on it tomorrow, with a friend who has more idea than me!

Success!

Put a new selenoid on, same problem.

Checked and cleaned earths to body with a bit of sandpaper and grease as advised and all good now.

Thank you for the replies
