Paul;

We'll have to agree to disagree on this one...

"an ammeter doesn't tell you anything useful because of it's crude scale, while a voltmeter tells you exactly what's going on."

I feel the exact opposite...a Voltmeter (even one with expanded scale) gives system voltage which is pulled up and down by a number of factors (and again, 0% to 100% Battery charge happens within 0.8V...talk about a "crude scale")...an Amp meter gives magnitude of current, and whether it's flowing into or out of the Battery, and THAT is what I'm interested in!

...hopefully we can also agree that EITHER meter, with proper interpretation is head and shoulders better than an idiot light only!

Cheers
