| I have a couple of non-loops that keep draining the batteries at rest (or the batteries are crap). Is there a simple test with a multimeter to determine whether there is a small drain on the batteries while the key is off? 73 Eldo in crates 78 T3/949 |
One of the easiest ways is with an Amp Meter which may or may not be a
function of your Multimeter. Disconnect the negative terminal, set the
meter to the highest amp scale, hook it up between the negative wire and
negative terminal and see if there's anything registering. Gradually reduce
the amp setting on the meter and see if anything shows up. If it's
consistently 0 then it's the battery. If it's more than 0, something is
draining the battery.
Oh yea, hook up the positive lead on the meter to the ground wire and the
negative lead to your negative battery terminal (I think I'm remembering
this hookup correctly).
