Hi George,

Yes I did re-use the wiring from the previous invertor. But I don't think it is a problem because last night I swapped the mains cable back to the original Moeller unit and it came on as before and showed the fault code again (no bang!). I also checked the plug fuse and that is OK. But just to double check I'll do a resistance check on the mains wiring to rule that out.

Given that all I've done is connect three wires EXACTLY as per the instructions, and it went bang on the first switch on, it seems a pretty straightforward case but lets see if the supplier shares that view. Out of interest the email name contains 'lovehappyshopping' in the title so it supports the theory of a few suppliers using multiple outlets under different names.

Thanks
