Hi, got a little help from a mechanic. After a short time of switches, battery and solenoid checks, he spotted that the fuse was missing! Bit of research told me it was a 15A car electrics type fuse; popped it in...fired up straightaway! I went to look for the old fuse where the mower had failed from earlier and its nowhere to be seen but as they are quite a tight fit, I fail to see how it came out.
Anyway, if anyone has a similar issue - Check the fuse!!!!
