With my battery dying the other day, I thought it would be a good Idea to keep a check of the new one, so I found Amp/volt meter in dick smith. This little panel can be made into a voltmeter or ampmeter.
I have brought 2 and made them up, 1 volt and 1 amp meter.

Now the question. Am i better to measure the amp drain off the battery or off a specific applicance. I was thinking straight of the battery.
If I go with the battery, is it as easy as positve wire onto + battery terminal and earth on to - battery terminal, or earth it on the truck, or am i completely wrong.

its too early to be at work....... and i am working in between this post..
