I use both a voltmeter and ammeter to check if the alternator is working as it should, the output from the alternator should be around 13 to 13.5 volts, amps will depend on the regulator.

That just goes to show how a little bit of knowledge does more harm than good, I said nothing whilst you wrongly suggested a volt meter should be connected as an Ammeter,

I cringed then said nothing while you mentioned cutting a lead acid cell open, (with or without acid still in there, residue will remain),

But to state that an ammeter isn't sensitive enough, Oh, please stop while I can remain polite, what do you suppose we, the professionals use to measure micro & milli-amps?

Please, Please, check your advice as much as you might believe it to be true, before you hurt somebody!
