I have a 78 z and was wondering which wire goes to the negative and which goes to the positive , i have a blue wire and a black wire . I think the person who had it before me switched over and i am confused

ps. will this cause my fusible link to blow when they are hooked wrong?

thanks in advance

FSM says Black w/White strip is the + terminal. Blue wire is the - terminal.

sweet thanks curtis, i looked at the FSM but i got confused when tracing the wires, ill take a look tomorrow morning thanks!

so if i hooked it up wrong will it cause the fusible link to blow?

also this one keeps blowing (circled in orange)

Hard to say if the fusible link would blow, but improper hookup sure couldn't help it.

I checkd my FSM and i cant find anything on why the links are blowing.. Curtis do u know of any source that would lead me towards an answer?

thanks again!

The fusible links are in all major electrical systems as the final link before hitting the battery. A lot of times the problem is just corrosion at the fusible links. If the links get hot only and not the wire leading up to the link, then it is a connection issue. If the wire is hot going to the link too, then you have a problem that the link is trying to protect by blowing. Electrical tracing is a methotical process. Start with as many things disconnected as you can and as you individually reconnect them check the fusible link for a change in state = getting hot means problem area.
