I've been searching for the draw on my battery and finally got the tester out and started pulling fuses. Found the glove box switch was not being closed and the light was staying on. This reduced my draw from 340 mA to 140 mA. I could not reduce the 140 mA any more by pulling all the other fuses. Is 140 mA typical parasitic draw for a 1994 computer controlled vehicle? I was also surprised that 200 mA from the glovebox light could drain a battery in 10 days, does that sound about right?
Thanks.

It's not 200ma it's 340ma. .340 X 24 X 10 = 81.6 amp hrs.
A lot of starting batteries are only 80 amp hour batteries, although they generally aren't rated in amp hrs. So I would say 10 days should do it.

Thanks for the correction on the 340 mA. How about the 140 mA that's left, sound normal?

It could be many things, propane detector, radio, clock, monitor panel or a dozen others. Pull fuses one at a time until it disappears and then you should know. Good luck

Is this an RV or car?

When I worked at a GM dealer a few years ago I was told 50 ma (.050 Amp) was an accepted figure. The propane detector in my PU draws 50ma, and the CO detector I'm adding will draw another 60ma or .11 Amp total. I plan on disconnecting the battery between trips.

I'll reluctantly admit it's on my wife's 1994 Pontiac Trans Am. Although not RV related, I posted the question here because I have such faith in the wealth of knowledge from the members!

50 ma seems to be the accepted number, here is a link.
Make sure your meter is accurate.(check it with another meter)

Had a like problem. Found out the radio has two power supplies. One for the radio and one for the memory when the radio was turned off. Batt would only last approx one week.Installed a On / Off switch to the power supply for the memory and turn it off when in storage.The batt has not drained down to date. I do try to use the motorhome at least every month. I try.
