Hi Andy, On the 3.6 4g solis it was giving the same fault, in the software three is an option to run the device with "ground protect" turned off. My solis has been running quite happily like that for a good few months now. It is in advanced settings, behind a password, on the solis the password is 0010, If I recall, the password for the uno is given in the manual. doesn't solve the problem, but makes the machine go again.
This looks like a capacitor isolated transformerless topology, the white boxes on the left of the board being the capacitors. Check them for leakage current and/or dielectric breakdown.
The round blue component has 'PTC' written on it I think ? Also, on the board, it's labelled 'F1', which to my mind means they've used a postive temp coefficient thermistor as a fuse, though it doesn't have very thick wire legs, so not a huge rating. Dave
@@TheInfoworks That's right Andy - it's a low resistance at room temp., then if too much current passes, the thing gets hotter and up goes the resistance, thus lowering the current. It resets itself when cooled down, so it's like an auto resetting fuse. You can get them with all sorts of cold resistances and characteristics, depending on your needs. (an NTC is, as you can imagine, a thermistor which goes down in resistance with rising temperature) Cheers, Dave
Have a 6kw old type one of these back in its box because of the dreaded GFI error Andy. Watching replies with interest because it's basically an uneconomic repair to sed it anywhere to be fixed. Pity cos it was better that it's replacement.
That blue thing under the sheath is a ptc resettable fuse if you look at the board it says F1 which means fuse number one. There is a white capacitor nearby that could be leaking causing the trouble. Wherever you get a leakage like this the first place to start looking is the capacitors, an in circuit capacitor tester is a good investment, something like the peak electronics atlas esr meter.
@@TheInfoworks I look forward to the next installment. I've got one of the older Auroras with a ground fault, so hopefully it'll be the same fault. Thanks for sharing your efforts.
@@simonduffy99 I've been trying to find the service password, hoping that there is a GFI switch off setting similar to the Solis inverters, otherwise it's board out and check the capacitors (winter project) Cheers
Wow…. I’m blown away with the knowledge of yourself and your commenters Andy…! If it doesn’t have a crankshaft or pistons I’m lost! 😄
Andrew, engines are just as complicated, it's down to what experiences you are subjected to, cheers

Owen, that would be good enough, these Auroras are just too sensitive, cheers

Thanks for your thoughts, looks like that board is coming out at some point and then capacitors out for testing, cheers

Dave, thanks for this, it only has two legs, so does that mean it has continuity until it gets too hot? cheers

Jim, there must be relatively easy fix, I'll try what Owen suggests first, Cheers

Hi, thanks for this, that means a board out and time to try this, cheers

The device you removed is a thermistor not a capacitor
Kelly, good to hear from you, yes I didn't realise it at the time, cheers
