I had an alternator issue on my 1989 Comanche not charging replaced the alternator, made my own battery cables out of no.4 wire. Still had the same problem. Checked all the fusible links at the starter relay using a test light no burnt fusible links as the test light confirmed. Sanded the paint around a small screw hole on the passenger fender well, took a piece of 10 ga. Wire and crimped a lug on each end and connected the wire from the negative battery post to the fender well problem solved (alternator charging @ 14) I wish that I would have started at the fusible links and started checking grounds before I bought an alternator I could have saved myself 165.00 and a lot of work on replacing the alternator.
