After scouring previous posts unsuccessfully I am hopeful for POBC to assist.
K series R400 Superlight SV 2004.
Standard Stack Dash
Thought I had a cooling system problem - high water and oil temperatures with low oil pressure happened on a couple of occasions, with all sorts of warning on the Stack. Yet track days and long journeys showed no problems. Examinations showed nothing. Happened again recently so took a look today.
Turns out it is some kind of electrical problem.
With the water and oil temperature and pressure up to normal, I noticed if I put the heater fan on, indicated water temperature jumped 9 deg and oil pressure fell by around 12. If I turned on the heated screen, similar situation. If I put them both on, water temp went to 104, oil pressure dropped to 15 and the Stack system was a Christmas tree. ☹️
Switch them off, everything is showing normal.
I noticed the battery charge fell from 14.4V to13.5V when I turned them both on.
I know this is a bit vague but has anyone had any similar experience and/or a suggested fix? I am booked in for the annual service at CC Dartford next month, which will be my (expensive) fall back. 🙅🏻♂️
Thanks
