Alternator ?

I noticed that my gauge is reading pretty high, is this normal?

 

It's not in the Oh shit zone, but best to test at the battery itself just to be sure. While running should be between 13.6 to 14v. Make sure you have clean connections at the battery while there.

 

I personally don't view it as a high reading if we assume there are 5 marks from 9-18 and that those marks are approx. 1.8vdc, your reading is approx 14.4 vdc on an idiot gauge.
BTW....that's where mine sits.

 

I'll have to check mine when there is light out tomorrow. I noticed it starting to ride higher on the gauge with each LED I installed on the truck. I just assumed it was normal because there was minimal draw since I changed from incandescent.


The gif is when I hit UP on both window switches with both being all the way up. I'm sure those motors draw some power!
I did notice that my exterior lights, and all my cluster lights dimmed.

Not so sure if this is normal.

 

Weird, mine doesn’t do that. I would get a multi meter and either have someone run the switches and you watch the display or if your solo use the min/max settings and see if your actually getting a large voltage draw from the window motors.

That needle reading is about where mine sits. Didn’t measure it prior to converting most all the trucks bulbs to LED, but feel the needle sits a tad higher since the LED’s.

My battery is 1 year new and here are the readings when On and Off (cold). Seems acceptable from studies by others
