I have 2 old electronic bug killers - same model. I recently brought them out
of storage - one worked and one had died before putting them away. The
working one was fine for a few days and then it died too.
The one that was working now seems to have a shorted step-up transformer,
because I only get 180 VAC across the high side (disconnected from the grids)
and there's almost no power to make a spark. I believe these things normally
put out a few thousand volts. I haven't checked the other one - I just put it
back away when this one worked.
Simple circuit - one side of the transformer gets 110V, the other side goes to
the grids. No protection from shorts (like if it rains or a big bug gets in
there, etc. The grids aren't shorted now, but certainly when it rains they
can get shorted. Each one has served a few years outside, and lived through
rain many times before.
No ID on the transformer except 3 groups of 4 digits that don't looke like any
specs - I think they're just part numbers. No manufacturer, no ratio,
voltage, etc. and no clue in the numbers.
Suggestions for repair ?? Suggestions for a protection circuit to keep from
burning out the next ones ??
