I recently inherited a 12Vdc > 240Vac inverter. A "Dick Smith M5100 150W". I have googled for a wiring diagram - or any info but nothing of use was forthcoming.
It looks like it has hardly been used so I presume it works. BUT... there are no markings for DC input. There are no unit terminals - just a raw cable exiting and it has been cut and ends stripped - presumable to wrap directly to the battery. I presume there may have been battery post clips at one stage. I read one post on the site where reversed polarity popped the works so I am cautious.
I have set a photo below in the hope that someone may conclude the obvious. I live remote so don't get to town often.
With a 50/50 shot I would guess that the wire with the writing, feeding to the transformer? would be positive.
Any thoughts? - on the image below or suggestions on how I might determine which wire is which.
