Background
We were away and were running our inverter to provide 220v
Then the inverter clunked off (the relay which switches between external 220v supply and
inverter 220v supply always clunks as it's mounted on a bulkhead wall that ampifies the sound)
Result No voltage from the inverter.
Check 1
However If I plug in the supply lead from an external mains source via the external socket we get 220v all round as normal.
Checking with a volt alert stick it bleeps and flashes ok when held against the power cable right the way to the relay and relay output
I THEN UNPLUGGED THE EXTERNAL SUPPLY
Check 2
The voltage from the inverter goes via a 13amp plug and cable on the side of the inverter to the relay
I have checked the fuse on the plug that's fine.
However when I hold the volt alert stick next to the output cable no bleep no light.
I thought aha ha the inverter is stuffed.
Check 3
I unplugged the output plug and cable.
I then plugged in a normal extension lead and switched the inverter on
the extension light led lit up so I plugged in a hairdryer and that ran
and heated up and blew hot air.
HOWEVER
When I hold the volt alert stick anywhere on the extension cable and hairdryer cable
IT SHOWS NO VOLTAGE NO BLEEP NO FLASH
I INSERTED MY AVO INTO THE SOCKET AND CANNOT DETECT A VOLTAGE
HOWEVER
WHY DOESN'T VOLTAGE FROM THE INVERTER SHOW UP
HELP
