For thos w/ old PB P/Ss. They are well engineered [not the cable tho.]
, when shorted work fine when short removed. I sold my first PB, a Ti
2001, to BIL. Yo-yo soon failed. I have an older new P/S [free yard
sale] w/ wrong plug so thought to substitute. Fortunately, in
determining connection (plug sleeve tip, etc.) to the cable after
unsoldering from torn apart yo-yo, I found the cable/plug was shorted.
So again fortunately checked the P/S; fine 24V. It took some doing to
find the short in the strain relief of the plug.
From an apple list I find these P/S fail frequently, but no one
mentioned what I discovered.
bc, if working, the repair cost 2X a new one! Tho next time will be
much quicker.
