Improving Volt Gauge Accuracy***Split From Wire Selection...***

That is dead-on where mine lives now too, and I took the same steps except for the inertia switch ground. Congrats! Have you measured your actual battery voltage with all the systems running? Turn on the stereo, headlights, brights and max a/c with all the doors open and measure the voltage at the pick-up post and block. Curious what you see there.

Too late to edit my post so... I just measured mine with all the doors/hood/engine cover open, A/C at max (cooling fans on), blower at 4, radio/sub at max volume and headlights/brights on. It was going between 13.9-14.2v at the pickup post/hoist loop but only showed just about 13 at the volt gauge. Not real accurate but a fair indicator of load if you ignore the numbers and know where it 'should' be

Hey Jon,

Sorry for the late response. That's a great idea and I see what your results were. You've got me thinking, though. I remember that rewiring the inertia switch didn't seem to be a night/day difference and it's interesting that you're getting the same reading without the switch being re-grounded. I think I got a real noticeable difference when I re-grounded the radio bracket bolt, like I mentioned before. I still have my stuff apart so I might do an experiment with that bolt. My courtesy lights aren't hooked up since I'm still putting the interior back together, but probably Wednesday I'll be able to run those tests you were talking about.

And you're right, the gauge probably isn't going to be incredibly accurate no matter what we do but there are definitely ways to get it reading somewhat close!
