I'd been having problems with my ignition wire to the starter on my 73 240z burning up, i replaced the wire and checked all the connections and everything looked fine. when i had it running i heard a noise in my amp meter and the wire burned again. i have since replaced the starter since i think it may have cause the problem. is there any other reason this may have happened. also my amp meter broke and now i need a new one.

If I recall, that's not just a plain wire, that's a fusible link. That's supposed to blow if something is wrong. You have another problem to hunt down.

Hope this helps.

the link did break but also the ignition wire to the starter burned up at the same time
