Subject: | a simulator mode |
4/2/2009
Hello Old Bob, Apparently the Garmin 400 and 500 series GPS units do not
include a simulator mode.
I found the term "demo mode" in my 430W manual, but no words at all on what
it was.

Bob,
There was a question that a few of us were debating and would be interested in
your input on.
Assuming you have a single battery installation and a good (regulated) alternator
doing its thing as expected (putting out 13.8ish volts), what would be the
effect on the system if the battery was disconnected (like if primary battery
cable came undone or was disconnected)? I know the battery acts like a capacitor
to dampen the bus voltage (and fluctuations from the alternator), but would
the alternator continue to output the right voltage in the quantity (current)
as dictated by the active loads on the bus? In other words, could you fly indefinitely
as long as the active load did not exceed the alternator capacity
(and assuming the regulator was working appropriately)?
Thanks,
Scott

I had that exact thing happen in a Toyota Corolla (battery connector
broke off). The car ran fine until the headlights were turned on, then
it ran very rough, then fine again once I turned the lights off. I
drove it several miles to a place where I could replace the battery
terminal.
