Trying to wire in an LED warning light to indicate when the pump is running. Anyone know how to do this (I am a leccy numpty) Seems the pump is constantly live and relays to earth' date=' or something like that :search:[/quote']

 

Pick up one of the 12V led's from maplin and run a wire to the positve and negative terminals of the pump this will put the LED in a parallel circut and when the pump is turned of the LED should light up.

 

p.s. the LED has to be fitted the right way round.. the long leg is the +

Or get the Display from Aquamist

 

 

Good advice;) as you have no way of telling if you have any problems, ie blocked jet, no water etc, so if your using the water injection as intended to enable you to lean out AFR a bit and advance the timing, you are asking for trouble.

I was under the impression that it was a flow display not a power display. Ive been using it for a couple of years now.

 

Oops! - Sorry, you hadn't posted when I typed that. I was talking about the LED connected to the power lines. A flow display is what you want.

i have connected mine off the relay that switches on the pump, so when the pump is running the light comes on, very easy to do. Just connect one side to +12V and then the other side of the LED to the N/O of the relay, proving its 0V that is switching for the pump to work, Make sure the LED has a resistor in series.
