Acceptable battery drain level?

GM spec on new vehicles is 40mA for what it's worth.

Thanks, just the info I was looking for.

I had a little time this afternoon to do some more troubleshooting. This is where things are as of now, not done yet. Working through it as time allows.

I have 4 power feeds at my positive bulkhead connector excluding the incoming battery feed. They are feeding: Vintage Air, Cooling fans, ECM and the battery feed to the main fuse block.

Have isolated the drain to two items. The Vintage Air has a 15mA current (wth ?) and the balance is coming from the keyless ignition module. Nothing in the main fuse block has a current draw.

I spoke with Digital Dawg and they advised that unless there's a fob in range I shouldn't see any current flow. I don't think the fob was in range but I will recheck tomorrow. The 15mA on the Vintage Air has me baffled. I am running a Dakota Digital climate controller. So I guess I'll be calling both of them too.

I know I can always use a tender, which I will in any case just to treat the battery right. Just bugs me and I have to find the source. My kids say I'm OCD...wonder if they are right ?.. LOL

I'll keep isolating, sooner or later I will get there...

0.035a is a limit on a lot of new vehicles with verious "bus" communication system. Barely even see anything near that when making sure no draw is present.
