<span>The saga of my 'dead' TS-2000 continues.</span><br>
<br>
<span>So after hours of deciphering schematics and finally
performing a radio autopsy on my kitchen counter I was struck with
this conundrum... How could the supply voltage read 13.8v at the
connector, but only 5.2 where the wire connected to the main
board?</span><br>
<br>
<span>At first I suspected the filter caps. They are soldered
directly to the back of the connector inside the radio, dead-bug
style. I cut they leads, one-by-one and they were all good &
no change to the voltage reading. In a fit of desperation, I
checked continuity between the board and the back of the PS; + was
good, GND, not-so-much. Huh?? It was measuring 2.5k ohm! I
disconnected the PS lead from the radio, 2.5k between the PS lead
connector and PS terminal. Ah HA! (he says - well, I really said
something else quite a bit more expressive but I'll leave the
specifics to your imagination) I pulled the inline fuse out - Yup,
it read not open, not short, but 2.5k. I replace the fuse and the
rig fired right up!</span><br>
<br>
<span>So, when is a fuse not a fuse? When it is a resistor!<br>
<br>
That is a new experience for me -- I'm def. NOT going to forget
it.<br>
