FT-1000 auto-tuner problem
 

I'm having some trouble with the auto-tuner in my Yaesu FT-1000 and I'm
wondering if anyone can help.

If I turn on the auto-tuner, even when I have a near-perfect match to the
antenna, the SWR goes very high and the output power goes very low. If I
hit START, the WAIT light comes on and then it just sits there, nothing
happens, only way out is to turn the auto-tuner off.

I'm waiting for a service manual to arrive and then I'll troubleshoot it,
but meanwhile I wanted to find out if any of the rest of you have seen
that problem, or if there is a common thing that causes it.

It's relatively unimportant at this time because I use an external tuner
with a ladder-line-fed inverted V, but I'd like the internal tuner to work...

The radio is an older FT-1000, no -D or -MP or any other suffix.

Thanks for any help...
