Mend Potterton Netaheat Mk 11 Boiler Heating Electrical

potterton netaheat Mk 11. Electrical problem?

After about 3 seconds of switching on the main fuse (1 Amp) blows.(The fans comes on straight away) I've replaced the relay switch and the spark generator, however the fuse still blows. Any idea what could be causing it ? All elecrical connections seem OK. It was working fine before going on holiday, and was switched off for 1 week.
