Didnt believe that the alternator didnt kick in right away, did a test this morning
batteries sat at 12.58v ignition key off.
turn key for cranking voltage, drops to 11.86v.
motor running start counting 1001 1002 etc.
voltage didnt increase until 1030.
after 30 seconds voltage jumped from 11.9v to a full 14.58v.
