Just a Little Oxidation

Just a little oxidation is all it takes with these cheap connectors to cause resistance in a high amperage circuit. The two pins closest to you are the orange and red wire pins for the charging circuit. Note how clean the low current pins are in the back ground. As I mentioned these connectors are not safe to run this much amperage through.

8/30/18 Just changed my plug at the engine connections and it was bad... Problem I had was that the wire colors didn't match up with the diagrams. I was particularly wanting to change the red/yellow 14 gauge line with a 10 gauge as indicated in this article. PROBLEM when checking for continuity of the line from one side of the plug to the other they did not match up. What did match up was red/yellow coming from the starter had to connect to a green coming from the instrument panel and the red/yellow coming from the instrument panel to the plug by the starter had to connect to the tan thermostat line. WELL QUESS WHAT ALL IS GOOD THE ENGINE STARTS BETTER THAN EVER AND THE THERMOSTAT WORKS. JRH Michigan
