Need some electrical help with my ‘68 Plymouth Valiant 100
Ground wires.
On '67 the original ground wires connection was from the body to the rear of the cylinder head. Then the engine block to the battery negative was just the large cable to the battery negative. Later on a second small wire from the body to the battery negative was used to increase and improve grounding capacity.
All of the wires going through the bulkhead connector are 'positive'. Black and red were used on the main power feeds.
Several are hot whenever the battery is hooked up. They are not turned off by the key switch.
After starting the current flow for running the engine and recharging the battery looks like this.
