Hi!,

My symptoms are:

- The in-dash battery warning light stays on after ignition is turned off.
- Warning light goes from very faint to off, with engine running.

Did this test:

- Disconnect neg. battery cable
- Put test light between cable and post.

Result: Test light stays on until I disconnect alt harness.

That's how I concluded bad diodes.

Opinions??

Thanks,

Edwin
