All,
I have been researching the archieves concerning E-busses. Typically, E-busses are powered via a diode off the main buss. This electrically isolates the busses. Most people also have a SPST switch which, when closed, provides direct power (bypassing the diode and the associated .7V drop) to the E-buss from the battery side of the master contactor.
A while back someone (Dan C., I think) posted that he always flies with the this "E-buss Direct" switch always closed. I was thinking of doing this also. So, why would I need the diode??? If there is a failure on the master buss or the alternator goes tango uniform, I just turn off the master buss. Am I missing something?
Thanks,
