"Tony Miklos don't know much"


** From the damage to the tranny visible in the photos - the primary has
developed an internal short ( due to insulation failure) and since there
is
no fuse link in series, the resulting current was high enough to make an
exposed wire leading to the terminals explode.

An internal short could develop due to heat alone because of an overload
on
the tranny - but this requires a fault to exist on the secondary side
which
seems not to be the case.

Oh my gawd, someone agrees with me. Looking at the picture says a lot.
Burnt on the primary side, looks like new on the secondary. And this is
the third transformer with an open primary!


I don't know about a the 1uF cap, seems way too high

** Why ?????

It ( likely ) needs to absorb a transient back emf generated by a powerful
blower fan.

Non puny size cap will ever do that and using 1uF cases no harm whatsoever.


so I'll delete what was below and pretend I didn't see it.

** Nothing like doing the old Ostrich trick when the brain gets overloaded.

Wot a jerk off.
