Have you looked at the bridge rectifier and filer cap before
your regulator?
yes, that was the first thing i considered just because it was
there next to the fuses
i desoldered the bridge and then
i tested the bridge by using diode tester on the DMM so i chose
the combination of pin checks that tests each of the diodes AC1
to (+) .,AC2 to (+), (-) to AC1, (-) to AC2
and each gets ~.596 (+- .007) volts till turn on
and there is no "continuity" between aany combo of bridge pins
thanks for help and reply,
rob
