Battery light staying on alternator and battery good, alternator fuse location needed

This isn't a fuse issue. Fuses will never be intermittent and cause a flickering warning light.

Fuse "T" is in the Power Distribution Center, (fuse box), under the hood. It's shown with my red arrow in the diagram. This fuse has to be good because it feeds other circuits for the injectors and ignition coils. If it was blown, the engine wouldn't run.

The fuse link, (blue arrow), is a special piece of wire spliced into the alternator's output wire going back to the battery. Failure of these is very rare. To verify it is okay, measure the voltage on the large output stud on the back of the alternator, with the engine not running. You must find full battery voltage there all the time. Use a test light for this measurement, not a digital voltmeter. For this type of problem, a voltmeter can easily give a false reading showing voltage is present. The test light puts a load on the circuit that causes current to have to be able to flow through the fuse link wire.

To diagnose this problem, when the no-charge condition is occurring, measure the voltages on the two smaller terminals on the back of the alternator. The engine must be running for this test. You're going to find full battery voltage on one of these terminals. The diagnosis starts with what you find on the other terminal. You're going to find 0 volts, exactly the same voltage on both terminals, or something in between. When the system is working properly, that second terminal will have typically between 4 - 11 volts.

If it was the fuse link that burned out due to a shorted alternator, that would be very uncommon/unlikely. A burned out generator fuse is a common occurrence on Ford products, but as I mentioned, on Chrysler products the engine wouldn't run with the fuse in the alternator's circuit burned out. Regardless, I'm happy to hear the problem is solved. Please come back and see us again.
