I seen the post where you were told to put a light on the ground cable, I've never tested that way. Remove the pos cable and put your test light lead clip on the cable then the point to the battery post, If you have a short/draw the light will come on.
If it does, Unplug the regulator and see if it goes out. Yes a regulator can short and cause a draw and still put out voltage as normal when running.
If it is shorted, You can run a jumper wire from your main switch to the regulator so it's only powered when running/switch is on. This would save cost of replacement for a while......
