Noticed recently the starter acting up on my '73. I have the stronger starter (can't remember where I got it as it's been a few years, but the same one on my '71 I got from Alan Johnson Racing way back when) and every so often I just get the "click" with no start- sometimes when cold, ocassionally when warm.
In the old days (and I mean really old days, back in the '70's) when that happened you'd hit the solenoid with a hammer and that would take care of it. This starter is probably 5-6 years old, but used pretty sparingly... now I'm a little nervous to take it somewhere if I'm not on a hill! Eventually it will start but seems pretty unpredictable. Any ideas??? |

The starting issue stems from the ignition switch circuit (complete round-trip with the yellow wire). All the diagrams that have been posted address that issue.
The reason for utilizing a Ford relay is that it takes less current on the primary coil windings to complete the connection between the contacts (large studs) when energized. Those contacts are specifically designed to switch heavy amperage (current). Whether one connects the battery cable directly to the starter's large stud or runs it through the relay, both methods cure the problem ... in other words, there's more than one way to skin a cat.
