Wrenches,

I'm troubleshooting a system for a client, and would appreciate your pass on
the following:

This SW4024 recently started burning up battery chargers (yep DeWalt), and
compact flourescent lights. Around the same time the microwave display went
strange.

It sounds like maybe some of the SW's fet's have gone south.

What do you think?

Is there any way to know what's going on before the inverter comes off the
wall (and a temporary substitute goes in for this off-grid client) and goes
in for repair? I'm really not up for buying an O-scope, though maybe there's
a modestly-priced attachment for my laptop. Thoughts?

Thanks!

Gary
