if im not mistaken if the link goes bad it wont turn over .will it ? i was thanking the wire comes from the alt to the link threw the firewall and to the amp meter and the back to the ignition relay i may be worng but thats my toughts on that some cars have two tho they have oe that between the amp meter and then comes back out to battery and the they have one that comes from the starter relay so guess it could be the link if it a car with two did you check for spark at the plug wires ?
