Hot Start
 

For a number of years, I had put up with the inconvenience of not being able to start my 1950 Merc/ Chevy 350 after the engine got hot. Turning the ignition gave me the click-click-click sound from the starter. After the engine cooled, it would start up. Finally I decided to try the Ron Francis HR-67 Hot Start Relay.
What a difference this made. No more click-click. Starts the car no matter how hot the engine is. There may be other ways to correct hot start, but this worked for me.
