Something is draining my battery to the point where my 1987 Volvo 240 goes dead. I had the battery loaded tested and proved good. I installed a new Bosch alternator thinking the current was leaking through alternator but the car battery still goes dead after 3 or 4 days of sitting in the garage. If leave the battery cables disconnected, the battery is fine. Following are testing results with an amp meter:
- With the positive battery cable disconnected, at first positive contact between Positive on Battery and Cable with a Fluke Meter, we measure 200 mA.
- After two seconds, the amperage reading drops down and stabilizes at
I suspect some type of electronic circuit board is charging up capacitors and then drops back to 80 mA.
Does any one have any thoughts? Does anyone have a better strategy to diagnose current leakage?
