Thanks Joe,

I now understand the potential problem with feeding through small wires and fuses. Embarrassed that I missed it. "Smoothing" was not really what I should have said. I hav ...

In adapting Z-07 and/or Z-19, I'm confused about the use and purpose of diodes. As I understand them, diodes allow current to flow in one direction, with a small voltage drop, but not in the opposite ...

Bob,

Don't know which message it was in, but you mentioned that you we were working on the last battery article for Kitplanes that would include lithium batteries. I hope you will look at the Eart ...

Thanks Bob. I particularly appreciate the caveat. If the runaway can really get to 200V in 5 ms, then I will have a hard time evaluating the potential risk.

In modifying Z-07 or Z-19 for my Viking engine, I will add over-voltage protection for the Viking-supplied, internally regulated, 40A alternator by ND. Based in part on Bob's demonstration in the lit ...

Eric,

I think that I misinterpreted the use of the word "average." (My aero, mechanical, and civil engineering degrees were not big on diodes.) Say, for the specific diode STPS60L30CW ...

At Bob's suggestion, I've been looking at double anode - single cathode arrangements in a TO-247 case, wired so that current goes through both diodes. My average amperage will be 6-7 amps (12 to 14 ...

Bob,

As someone who has a Viking engine and who has been looking to modify Z-7 for my electrical system, I'm very interested in this thread. First, where did you get the diagram at the top of yo ...

Thanks Bob. Just the kind of advice I was looking for. Glad I didn't rush to respond to you earlier message.

Of course a higher voltage drop leads to a higher heat generated and, hence, for many of us, the attraction of the Schottky diodes. I've been searching for single diodes to use in a modified version ...

Bob,

I had previously selected to get a daily e-mail, so I must look at the HTML version of the messages to reply. When I do so, the message to which I am replying doesn't get copied into the new ...

I haven't figured out how to easily insert my response with parts of the message to which I'm responding. Sorry for the difficulty this creates in understanding my comments.
