The fuse is not being put forward as a solution - just to avoid
blowing the transformer while finding the real problem.


** The fuse will actually help you diagnose the problem.

If the fuse opens soon as AC power is applied - the tranny is being
overloaded.

If the fuse opens after some time because insulation in the primary side has
failed, replacement fuses will open immediately despite the secondary being
disconnected.
