Hello all,
some days in the past I used to be driving my 1978 R100RS regurarly; as I fired the headlight flash, the engine misplaced RPM and the generator mild got here on only a second, then every part went again to regular.
I did once more a check, firing the headlight flash (only a very quick time) and the identical occurred.
At house, with the engine idling recurrently, I switched on the lights and the engine was killed instantly and the dashboard lights had been all off.
I did these preliminary checks:
– battery voltage: 13.2 V
– visible inspection contained in the headlight bucket, no indicators of injury
– visible inspection of the left handlebar swap (unscrewed and regarded again), no obvious harm
– indifferent the battery cables and the 30 spade connector of the sunshine relay (see pos. d within the wiring diagram) and examined the resistance between the ends (lower than 1 Ohm); resistance 30 to floor = infinite

In addition to I noticed that the when the ignition secret is at 0 the clock works; as the hot button is switched to some other place no dashboard lights come on and the clock stops. As the hot button is moved again to 0, the clock restarts.
I owned this bike for a few years, however I’ve pushed lower than 2000 km (about 1000 mi)
.
The earlier proprietor had changed the principle headlight bulb with a xenon one. I eliminated every part and restored it to the unique, however I believe the system might have been overloaded and broken.
Any thought what to test?
Thanks a lot.
