I recently completed the restoration of my 62 TR4, which included the installation of a new wiring harness, battery, and voltage regulator. I also cleaned up the generator and installed new brushes. With the battery fully charged, the car fires right up and runs all day, and there's no drain on the battery while the car is running or sitting. However, each time I start the car, it depletes the battery's power a little bit until it won't work anymore (lasts about 10 starts or so). Jumping the car will get the car running, but with no consequence to the battery (it won't recharge). Once depleted I have to hook it up to my trickle charge, after which its good for another 10 or so starts. Additionally, the ignition light doesn't come on when you turn the key, but rather will glow randomly while driving sometimes (usually when the battery is running a bit low).
So, with a new voltage regulator installed (I also tried using the previously working original as well) and a presumably functional generator (I haven't checked it, but the car runs fine so I presume its working), and a functional ignition light system (the bulb isn't burned out at least), does anyone have any ideas as to what's going on? Do I need to re-polarize the system to negative ground (already was before I installed the new harness and regulator)? If so, does anyone have instructions for how to do this without burning out my brand new harness? Do I need to go back through my wiring and check for mistakes? Could the generator be the problem? Greatly appreciate your thoughts.
