A battery is pulled low because of high current and resistance of wires and connectors. Basic Ohms Law stuff.
1. I wonder if the starter is working harder than it should because it's been sitting for nearly 20 years, hence drawing more current. Similarly, The engine hasn't turned in nearly 20 years, so I suppose that load is higher too. Any thoughts out there about current loading with the long idle engine and starter?
2. The wire path to the ECUs may be long, but as low(er) current devices, I wouldn't imagine voltage drops across connections and wires to the ECUs would be significant. Curious to know your experiences.
It seems (to me) that the trick is to minimize load, and minimize resistive losses along the starter circuit. What say you?
My interest is to increase the crank voltage.
