Yep - I agree.. first you need a copy of the manual with schematics.

You could follow the wiring back to the PPB - I think it will be the transistor labeled Q13.

Schematic will prove that definitely. The coil should be a 23-800.

Thanks guys....This is now crossing into the slightly harder side of repairs!...
Can a dodgy transistor cause fuses to blow or should I be looking for an exposed wire etc...The fuse blows as soon as it powers up each and every time...The coil is definately correct.  Even with the coil unplugged (from under the PF) she still blows.
Would I be better to find new boards or take them to someone if I can't find the prob?...

BTW the flipper issue sorted.  It seems I may have fitted the spring to the coil stop around the wrong way.  A bit of fiddling and all good there...
BBTW the diode from DSE worked a treat on the leaf switch too!

Thanks again....almost there!!
