discharge/overcharge?

Sorry for no caps, anyway I was feeling like the "lost" volt is the issue, I done the "mad" repair to correct any issues with the bulkhead connector. I replaced the red and the black through the bulkhead and also "overlayed" the blue wire from the ignition switch through the bulkhead (just at the bulkhead), but I'm still a volt short at the regulator connector and at the ballast resistor. If I put a jumper from the battery to the "I" terminal it charges correctly. From all of my testing it looks like I may have high resistance in the welded splice, all the wires that come from that seem to be affected and dropping that 1 volt but nothing else.
