i am back on the BC7000 after receiving a replacement powerpack……sorry to say,

but Glitch was right in assuming the powerpack is ok…..and as far as I can tell it is !

here is what happens:

if I plug in the naked powerpack I measure about 6VAC across pin 1-2 and about

22VAC across pin 3-4.

the moment I connect the powerpack to the PS board its fuse blows – p2 and p3 are still disconnected.

so far I have not found a faulty component on that board nor a broken track that may be responsible for  the constant  blown fuse in the powerpack ???

every single component I tested was fine which begs the question ‘where from here’ ?

Obviously there is a problem I can not see nor measure.
