Help please! I either have a marginally bad battery or I have an unknown current draw to cause a dead battery? I put a test meter on ohm setting at X10 between the pos and neg cables (battery removed) and I get a slight movement of the meter needle - I don't recall the actual reading. So I opened the side door to simulate for the dome light to go on and got a major jump of the meter needle. Is this a valid test to verify a current draw on a vehicles battery? Should there be any movement at all of the meter needle if there is zero draw? Or am I totally out of bounds on this? Thanks, Steve
This is on a 1990 Ford F-150 with about a 5 or six year old battery - only the 2nd battery that's ever been in the truck since new - @130K miles.
