Totally dead electrics while riding
I purchased a 97 K1200RS with 39,000 miles just over a month ago. The bike has run well for a 1000 miles this included 'normal' rain. I then rode 30 miles in heavy rain, did a couple of journeys in light rain and then another journey in very heavy rain. On this last ride on a motorway the bike cut out for about a second, this included lights and instrument panel lights - I did notice the ABS and low fuel level light flicker on - the bike then came alive again. It did it again several times over the next 6 miles cutting back in after a second. A few miles later in a town the engine and all lights went off. On turning the ignition off and then on there was no noise from the fuel pump, no instrument panel lights and now headlights, brake lights, clock, absolutely nothing. Turning the ignition switch to park - there were still no lights.
I was not able to do anything for a few days and left the bike in a car park. On returning it was still dead, however after trailering home for about 14 miles it started and everything was fine, so seams as if water was causing the problem and it dried out. The dealer I bought the bike from claims to have found a broken lead and spiced a new wire in and the bike has run fine since although there has not been any heavy rain to test it in.
On putting the BM on my bench to service it, it appears that the dealer did not take the fairing off judging by stuck bolts and the only signs of a repair were some tape over the two leads that come from the start and cutout buttons on the right bar (I'm guessing that what these are). Taking the tape off did not reveal any faults with the wire and no repairs. It seems to me that it would be very difficult to access any more of the wiring without removing the fairing and therefore in reality the dealer did nothing.
I believe that engaging the cutout should still leave the lights and instrument panel working so a fault with these wires would not lead to a total blackout. Apparently the dealer did not look at the ignition switch. The battery was/is fully charged and when the electrics worked again started the bike with a healthy turning speed.
Could anyone suggest a cause for this failure? Thanks, Mark.
