Trying to track down if I have batteries going bad or not.
Story: I'm having issues with my headlight all on mod not working- my highs would stay on when i switched back to lows- and couldn't figure it out. Finally one day I randomly put a battery tender on my truck. Took like 3 days to be fully charged. Bam headlights work like they should. After a few days/week though lights will start acting up. I've narrowed it down to batteries I think.
So my question-
1- I tried checking the amp draw on the batteries with truck off. Anyone know how many milliamps it should be? I assume with all the electronics in the truck i won't get 0.00. But first check I got 0.02-0.03. My manual with my multimeter says most vehicles should be 0.01 or less. Is this true for the dmax?
