Blew another damn transformer on my Trane XB80
"Don Klipstein is Full of Bull "
Measure both AC and DC current through the secondary of the transformer.
If putting a multimeter into DC current mode gets a reading around or over
50 milliamps (,05 amp), then something is wrong with the load.
If DC secondary current is near or over 200 milliamps, then,
"Houston, we have a problem"!
** Simply fitting that DAMN 1/4 amp s-b fuse will tell you immediately if
any such problem exists.
Significant DC in the secondary will causes high current to flow in the
primary ( due to core saturation) and BLOW the fuse !!!
If the 1/4 amp fuse holds and the tranny does not get stinking hot - all is
OK.
