I stumbled across this clamp on DC ammeter at: http://www.powerstream.com/DC-clamp.htm Does anybody have any experience with these or similar ones?

From: "Hinde, Frank George (Corvallis)" Your first clue is that it is expensive...that tells you its about what you should pay. But answer me this...Why on Earth would you want to spend that kind of money?...HArbor freights $2.50 multimeter has a 10A shunt (namely will measure up to 10 amps) . This should be adequate for 1/100th of the cost. Incidently the HF multimeter is very accurate...at least mine is.

From: "jetboy" Greg, You might find a similar one for your needs at Newark / Farnell / Radiospares catalogues. ISO - Tec is a nice small low cost type or go for a Fluke. My one is 400 amps DC Sanwa and works well. If you are going to measure starter currents you will need this range. This is a required item for diagnosing Rotax 912 problems as described in their SB. Clamp meters are very handy for checking current drain and charging systems. A normal DMM with 20A range can do most things but many of the clamp meters include the DMM functions too.

Simple panels probably only have 3 or 4 audio sources (including alerts) and a full audio panel is way overkill. Most folks don't even use the speaker any more, so phones only are OK. I was thinking of a simple audio mixer and a Tx1/Tx2 switch.. perhaps from a ready made kit... such as this one... http://store.qkits.com/moreinfo.cfm/FK652 Would like to hear other suggestions.... gil in Tucson PS I got a working PM1000 intercom for $50 on e-bay, so the intercom bit is taken care of...

Is this correct? Is there any way to get full regulated DC output from a PM alternator if the battery is isolated from it?

Choose the wattage to suit?
