I've got several inverters that probably just need a fuse or some simple part, from trying to draw too large a load through them

also, on ebay i've seen a number of parts to a diy kit--power boards and modules from china to build a pure sine wave inverter, and i wondered if anybody had any experience with that-- i'm guessing with all the old burned out inverters lying around i probably have many of the peripheral parts- fans, connectors, case, so just buying new innards (if i knew how to put them together) might save lots of money

Many 12V and 24V inverters use automotive blade fuses - they are cheap and easy to replace. I would open the inverter housing and pull out the burnt ones.
What type of inverter is it: MSW or pure-sine? I had several pure-sine blow out fuses but there was actually a short on the circuit board.
Good luck!

I have all sorts of cheap inverters, and have basically looked at the insides (and outsides on some) for those obvious blade fuses, and so far have had no luck

in fact, i also have looked for obvious burned components or any physical indications a part might be blown, or some other fuse type arrangement on the board

i'm pretty sure most of them are msw which is why the modules i saw from china seemed so attractive-- looked like about 40$ worth of circuitry and i might have a 4 or 500 watt pure sine wave scavenging misc parts from older inverters

this is the main board

i think there are a few misc parts (caps and such) and i just wondered if anyone has done this
