I have a 66 dart. It does not have any power to the lights, coil, it just won't start. Could it be a fuseble link from the battery.

Do you hear a tick or click or anyohter noise for that matter when trying to start it?

It does sound l ike the fuseable link is burnt, or battery terminals corodded. Or perhaps your battery just gave itself up. Assuming the link is bad, you need to find the cause first before you replace it
