We won’t get the full picture drip fed info. A sparky does electrics, something dun add up.
Wait for Marty see what he says
my thoughts are start with a DMM at starter and get someone to turn key and see if it's getting power and work back...he's jumped starter and it's ok...thats what Barry does with me to trace electrical and a\c faults you need 2 people one on meter the other on the switches...
