EagleRJ said:Don't have anything besides light bulbs running if you do this, because the raw 14V output from the alternator will be hard on avionics and other gear without the battery acting as a buffer.

Huh? I don't think this is correct. Assuming the alternator contains an internal voltage regulator, its output will be around 14V DC. Most 12V electrical systems are actually designed to draw from this slightly higher voltage, because such a voltage is necessary to keep the battery charging at a faster rate than the discharge rate associated with the operation of various electrical devises. Subsequently, you'll likely find that a fully charged battery, with the engine running, will actually measure well over 12V with a multimeter. In other words, the battery does not act as a "buffer" and it isn't even necessary because the electrical system is designed to handle 14 volts. Not sure what you mean by a "buffer". If certain avionics equipment requires a reduction in voltage, it will be accomplished through the use of integral, solid-states devises. The battery is simply a box utilizing a crude chemical reaction to store electrical energy. It is not a buffer, and is certainly not used to reduce voltages/amperages for the operation of avionics equipment.
Also what is the difference between "raw" voltage and "refined" voltage, assuming they're both DC?????????
Not nagging, just wondering where you came up with this....

EagleRJ said:The power supplies in most avionics are able to handle input voltages from around 10V to 30V, to accomodate installations in both 14V and 28V aircraft. It's noisy, unstable power they don't like. One of the functions of the battery is to help absorb that fluctuation and stabilize the voltage for the aircraft's systems.
