Re: need help

Re: need help
 

yes there is a fusible link up by the firewall... i cant get to my gas truck or id give you a pic.. perhaps someone else can

Re: need help
 

the one from the starter to the firewall i have changed that one all ready and i have looked at the one to the alt. and it seemed to be in good shape other then the with that connects to the harness that goes to the fuse panel there is a little bit of corrosion there
thanks

Re: need help
 

I blew the one on my 75 recently. Look at the harness for a black connector. If you pull it apart there is a fuse in there. There Is another one closer to the fuse box below the master cylinder.
