At idle you often won't get any useful charging action - and you're not
really supposed to let these things sit and idle anyway. I'm not sur
eif this is due to the regulator not quite kicking in, or perhaps in
your case (new alt.) the belt is not quite grabbing at idle. I'd
suggest that in place of your 15 minutes of idling, you take it out for
a drive. The higher revs should help keep the charge up on the battery.
You definitely want to get the engine and exhaust heated up properly,
or you'll rot your exhaust out with condensed combustion products.
You might also invest in an appropriate trickle charger to keep the
battery happy between runs.
