just checking out my indicators and hazards as been renewing the units anyway. substituted my indicator can for one that emits a warning bleep as well.................jolly good idea, ..........anyway just checking it and discover that the input voltage as you would expect is 12volts  ishh    however the output voltage is only 4volts,  isshh     the indicators work fine etc etc but just slightly confused as to why such a seemingly massive voltage drop over for what is only a little flasher unit?         curious somewhat.

 

is only a two pin unit so easy nuff to wire in.

Are you trying to measure the voltage of the flash? Most multimeters cant measure a rapidly fluctuating voltage, so youll just get a nonsense reading.

Most digital multimeter's are too slow to register the on/off voltage of the flashers, same applies to the old bi-metal 10v voltage stabiliser for the gauges.

An analogue meter will usually show the on/off voltage.
