My car ran good for six months. Went for a drive car died. It has a two wire alternator that is still wired to an external voltage regulator. The car will start if the wires are removed from the alternator. There is a fuse wired into the positive terminal on the power wire to the alternator. When alternator is in circuit that fuse blows. Car has new ignition switch and a new relay for the horn. Any info is appreciated.

welcome Marty
is your alternator dash light in the same power wire with the fuse ??
I assume were talking about the excite wire, not the big charge wire ??
did you have the alternator tested yet ??

on the older cars with a external regulator,
it was normal to have a Fusible link on the charge wire/side and battery side..

what year Elky / Cruck ??
what size is the fuse ??
what Amp Alternator ?? got a big stereo/amp ??

don't know why fuse would blow unless the Alternator is putting out too much,
or there is a short, or too much load..

if it starts and runs, and everything works with the Alt disconnected,,
start there..
i'v seen bran-new Alternators be bad,
usually its the re-built ones, that is really common now days..
