Got the Bonnie rewired with a new handlebar switch, a nicely made item from Sparx in the UK. Well, all the light, horn and indicators worked out good. Coloured wire to coloured wire. So… I took ‘er out for a run around the blocks for a cobweb blow; all fine and dandy. A couple of start and stops to see it kick over. No problems. Bring it back to the garage and kaput! Dam, dam and blast it! Nearly there… But not quite (quietly fume).
