well went to start the car today no go reset the management system to link the batteries and away she goes , put the multi meter on 12.6 at the battery , then put it on the alternator 12.6 , gave the car a rev 12.6 switched on the head lights droped down to the low 11s and never came back , both batteries were good on the hydrometer , belts all tight so looks like back to the sparky that rebuilt it last week , starting to think that maybe something is upsetting the alternator ,
