Richard_E Posted June 12, 2002 Share Posted June 12, 2002 Hi Folks, I have been trying to fit a high intensity LED for the dashboard indicator lamp. I have wired this into the indicator switch using the same process described for the audible buzzer. The problem that I have is when the indicator switch is in the off position the LED glows dimly. This is due to about 7.5 volts being present between the centre pin on the indicator switch and either of the outer ground pins. When the indicator is moved to the left or right the LED glows brightly with a pulsing 0 – 12 volts. Could somebody please put a voltmeter across the back of the indicator switch when in the off position to see if you also see a reading. For me this was between the centre and either side position. Thanks. Link to comment Share on other sites More sharing options...

Adam Posted June 13, 2002 Share Posted June 13, 2002 With the indicator switch off, my center pin sits at 12V (ish). Not sure if this helps ... typical bi-metal flasher circuit: +V / X X {bi-metal flasher unit) X / a / b (indicator switch; switch to a,b or off) / / /-O-/ (flasher warning lamp) / / OO OO (flasher lamps) / / GND hmmm ??? best viewed with courier font....
