Question 1

What is the correct wiring/connections for the 12vDC from a battery to a light? What gets connected to LOAD (Red), NEUT (White) and LINE (Black)?

Accepted Answer

Positive side of the light you're controling goes to red wire, (negative side of light goes to battery negative or ground)Black wire goes to positive 12v terminal of battery.White wire goes to negative 12v battery terminal or ground.

Question 2

I want to control a 12Vdc pump in daylight. Can I reverse the electrical wiring from the sensor? or do I need a switch in-between

Accepted Answer

Connect your battery/source ground to the pump ground, relay pin 85, and the white photocell wire.  Connect your battery/source positive to an appropriately sized fuse holder, and from the fuse to relay pin 30 and the black photocell wire.  Connect the photocell red wire to relay pin 86.  Last, be ready for the pump to come on and possibly a slight spark as you connect the pump positive to relay pin 87a.  (Or do this at nighttime, LOL.)  Daytime operation:  photocell puts out no voltage on red wire, relay stays closed and pin 30 feeds voltage to the pump on pin 87a.  Nighttime operation:  photocell puts out voltage on red wire, opening relay and disconnecting pin 87a from pin 30.  (And connecting pin 87 to pin 30 -- not used here but including for clarification.)  With relays being made more cheaply these days, I wouldn't recommend this for a pump continually drawing more than 15 or 20 amps.

Question 3

Is there any way the light sensitivity can be adjusted?

Accepted Answer

The only way that I know of to adjust the on and off sensitivity would be in placement of the sensor, by pointing in the direction of sunrise then they would possibly go off quicker, otherwise I have not seen any adjustments. Hope this helps.

Question 4

Can this do lower voltages? Say 3.7v or 5v?

Accepted Answer

To reduce 12v to 5v you need a circuit known as DC-to-DC step-down converter.
