Question about 1998 Ford Mustang
I put new ends on battery cables and new alternator problem still there
Increase idle rpm's to around 750-800 and there will not be a problem. another way is to put a smaller drive pulley on the alternator or a bigger drive pulley on the crankshaft.

Possible loose or worn alternator belt. Check the condition of the belt. If it's worn, replace it. If it's just loose, tighten it up.

SOURCE: battery light on.
some ford vehicles have an external voltage regulator. when theres more demand for power it gives it. but when theres too much itll lower it so it does not overcharge. at 1600 rpms there is more demand, plugs firing with more fuel in the cyl, if the alt is working properly the regulator could mess up and stop power from the alt. its a cheap fix or tryout...another big problem is ground if the system does not have an adequate ground nothin would work as it should.

either the belt is slipping or the alternator is losing juice at a lower rpm....i take it it was checked in park,or taken out and tested by a machine which spins fast?
