Not all voltage regulators are created equal!

A while back my voltage regulator died and I replaced it with a solid state unit sold on eBay. I won't put the name of the seller because their description of the item makes it clear they are VERY active in the Mopar community, but I definitely had bouncing voltage. It charged the battery and I couldn't be sure it was just the regulator so I left it in and worried about other things for a while. Recently decided to address it by buying another from a different vendor. They're cheap and I figured it wouldn't be the worst thing in the world to have a spare. The new one (sold by starting-n-charging) was cheaper by $3, heavier, and used composite instead of cardboard on the back. I installed it and my gauge is now rock solid. Turn on the lights (85w H4) and it drops briefly then right to the same spot as before. Crank the A/C fan, music, and high beams and I get a very small drop but still rock solid and above 12 at idle.

Previously the bounce was so bad that headlights would pulsate visibly at idle.

I am pleased.
