Re: battery discharging-battery strap
For a start, think about adding a voltmeter to keep tabs on this; even the
cheap type that plugs into the cigar lighter. Sometimes the wire from the
alternator light to the alternator gets intermittent, and the alternator
won't start to charge. If the alternator passes a voltage and load test,
check the individual connections and the strap itself. If the battery lost
charge since it wasn't getting any from the alternator, it should still
pass a load test. I'd check that as well.
It would seem very strange if the strap needed replacing. Bad connectors I
can see, but thay can be checked individually be anyone with a voltmeter.
Think about going to an electrical specialist shop.
