Relay is staying active for a good long time.
I did not put a stop watch to it, but felt I was easily
at 20 seconds (only expected 10).

I was able to move my volt meter probe from post to post 3 or fours times
around before it gave a noticeable click and shut off.

At first I assumed it was the bulb on the dash for GP that went
bad and simply waited an appropriate amount of time to heat the GP's.

Except that the car was hard to start, which made me think the GP's
really were not getting hot.

Since then I know the bulb is okay.

I disconnected the harness at relay, took it apart and cleaned it and
crimped the connectors a little to make good contact.

Oddly when I fiddle with the relay connectors or GP's the dash light
seems to come on as expected, but only once or twice.

This weekend I will pull the ignition switch and study the contacts
to see how corroded they are.
