The 85 and older Mustangs and Capri's had an externally regulated alternator, so the wiring is different from the 86 and later cars. Herer's the fix:



I recommend that you use a 125-150 amp fuse and 4 gauge wire for the power lead. It is a better match. You won't be able to use the Ammeter if present because it isn't rated for the full current capacity of the alternator.

See WWW.partsexpress.com for the fuse & fuse holder.

Pre-fab 4 gauge cables with lugs already on the ends are available in most auto parts stores. Look for the starter switch to starter cables.
