Hi, I recently inherited a SR8F51 from a friend. He recently replaced the battery and it appears to be charging after checking with a multimeter (approx 16.5v). I get the 3 pips to indicate that the battery it full.
Should the display light up when charging? it doesn't.
When I turn the vacuum on it does the 5 second countdown and then I get nothing. No lights, no buttons, nothing.
Here is the strange thing. If I put it into diagnostics mode it springs into life. I have run through each mode and don't get any errors.
Any ideas of what to check? Any help would be appreciated
