Can you post a pic of where the leak is. If you need to get it soldered I would think £45 - £90 to get it done. Should only take someone about 30 mins from arriving to finish, quick end of day job .
trace the feed wire back and test where you can for voltage I would suspect a problem around steering column from when you changed ignition switch, have you got a feed to the column switch?
motor bikes dont have front plates.
Technically it should be mounted on the vertical surface nearest the front of the car. So get a plate and grind it out to the shape of a speed hump and stick it on front crossmember ( a damaged plate or missing plate will only get a report to mot station and pay for test and then a producer at local nick).
This was just a simple mistake just. Hope my name was on the list and it is flying round the internet being published on servers world wide, that will help promote the business website.
Foxton locks is not far and worth a visit Market harborough is a lovely town to wander round and has a great wine shop (Duncan Murrys) as well as a real ale shop and also a micro pub. For those who want a trip out a bit further afield you have Rutland water, or head in to leicester for the national space center or the richard the third visitors center
