Question about Honda ST 1100 Pan European (cbs-abs met TCS Motorcycles
Is the driving light and speedolight supposed to light when motor is not running?
the lights works when the engine is running. and the light increases in strength as the throttle is increased.
i have changed the battery. i know that it works. the horn and left/right turnlight works when the engine is not running. same with breaklights.
another fault is that the button-motor-starter doesn't work. i have measured the voltage and everything is correct up to the actually starter, so i guess that is the part i have to replace. Can this be the cause of the other problem?
thanks for your replies!
The driving light and all the 'dashboard' lights are supposed to be ON when the key is turned to RUN--even if engine is not running. (blame federal regulators for this dumb idea. Driving light should be wired to come on when engine is running--a simple wiring connection change.)
the comment 'and light increases in strength' is a key clue. It describes low battery voltage. Either the battery is not properly charged, or it is faulty. First try 'jumping' the cycle with a good car battery. If the started works--proves the problem is low battery voltage.
The alternator is working--but is the voltage regulator controlling the voltage? Try measuring the battery voltage (not driving) but in neutral at various increasing engine speeds. The voltage across the battery terminals, everything off, should measure about 13.2 volts. With engine running, it should quickly rise to 13.5 V at or just above idle, and not rise much/any more as engine speed increases. If it keeps rising to above 14 V , the voltage regulator is not working and will quickly overcharge and destroy your new battery.
