Thanks for all the input guys... much appreciated.
Tangles, I was asked if i lived 40km's from the CBD by TransportSA, that being the case i've been told that I have to goto regency rather than a police station. Think i also read that on the TSA website.
Mad082, yeah looking at the diagram you would think that's the case right? The TT just sends a kill signal back and it switches off?
Or if fry is correct, then one of the line's is working as a switch? which case I should just bridge it again once the TT is removed?
