Battery Light

The battery light came on, two days later I lost power, the tach went to zero, I am still cruizing at 70mph, five minutes later, the engine died.

I can go about 2 miles and then Blaaaaaaaaaaaahhhhhhhh...

I took out the alternator, Shuck's tested it, said it was fine, I put it back in the Corolla.

I took the battery out, Les Schwab tested it, said it was in excellent condition, I put it back in the Corolla.

I don't know what to do now?

Please help me.

Thanks.

It a 1990 Corolla A4-FE American engine. SR5 2-door.

Check the alternator fuse.
