Car power/start troubles

Yep, as writen.

The wire out of the bulk head labeled block "P" as per on the diagram. And it should say I do have power there. In and out of the ammeter as well.

IF YOU ARE RIGHT that P is dead, that goes through the bulkhead to the "IN HARNESS SPLICE" and from there to the ammeter.

I'll repeat--I've seen those splices fail.
