He said the system was only 12 volts. Howya gonna charge a bike battery
w/ that? Rectifier isn't gonna jack the voltage up any...

The 12v was *nominal* from his book. I'm *betting* that the raw unloaded AC
peak to peak is more than 12v - and a full wave bridge will net him peak.

Even so - unless he wants to convert the boat to a 9 volt system - it's the
best he's gonna get.

It'll cost him $5 and some time making up a few wires to try it - with a
real decent chance of success.

Ah... I get it. The book sez 12v, but could mean anything (we call it a 12v battery,
right?) so there might really be enough DC to do something.

Thanx.

Not a problem. "12V AC" is usually 12V RMS - meaning nearly 18V peak. A
full-wave rectifier will out put two nice 18V peaks per cycle that will charge a 12V
battery just fine.

The problem might actually be "too much".
These unregulated systems tend to boil the water out of batteries.

Correct................ I live that case - he still wins though.
