Do 748s have bullet connectors between the leads off of the brake lever switch and the loom (as 749s/999s do)? If so, they may need a clean and some re-seating.

Yep they do Loz, so they can always be pulled apart and the two ends from the main loom shorted together to check its not a break in the wiring in the harness.
If its the same problem as Brenda's (Mrs Everton to some) then it could well be a naff brake switch
Yeah im having a similar problem, i've got a brembo radial master cylinder and with a small hand full the lights don't come on but with a large handful they come on, was told to look at the relay switch from the master cylinder? think i've located, its a couple of wires which attach at the bottom of the cylinder but can't see any obvious problems? any ideas?????????

The wires you describe there are from the pressure switch, which the Radials have instead of a mech switch as such on the standard items.
Not sure there is anything you can do about it really?
If you listen carefuilly (engine off, ignition on) you should be able to hear a "click" from the front brake microswitch. If you can't hear a click, the switch is misplaced/missing/broken.
They can become displaced. Mine has two tiny lugs which locate in two holes in the handlebar switch/master cylinder assembly, although I believe there are two different types. Pull the switch out, give it a squirt of WD 40, test that it works by pushing the button, and carefully reinstate it.

Yup on on the monsters we have to use a small piece of crumpled of tin foil to make the connection and make it click - I know - been trying to sort ours out all weekend
