[ROVERNET - UK] Re:Starter relays

[Reverend Weasel]

The starter and solenoid were replaced as a unit earlier.  After
removing the relay, it is marked 22RA under the rust.  With the relay
free, the wiring looks more than a bit tatty. I suppose I will have to
try each wire and work my way through it.

I used to service busses, so I guess I can find my way around a Rover.
 hmm, well maybe not.  Still, at least there's no air assisted starter
solenoid like the Flxibles used, so that's a plus.
