I bought a digital voltmeter at Target a few months ago for about 10 bucks.
I hooked it into an always-hot wiring circuit and mounted it right above the
radio, where the console light was before it was DPO'd. Now I always know
when something is right or wrong with the charging system. It doesn't do
much for originality, but it does wonders for peace of mind.
