Re: Power Debugging
When I worked at Hughes back in the 70s, we were building the Intelsat 4 satellite. It had a small battery, the Aux. battery, which was used only during launch and then only if the main battery was knocked off line. After launch the main battery would be brought back on line, and the Aux. battery would be disconnected. After several launches in which nothing happened and the Aux. battery was never used, an engineer was looking at the circuitry discovered it would have never worked. If it had been needed we would have lost the satellite. Changes were made, but they never need it.
