Although our beloved D2s have plenty of electronics, I miss not having a Voltmeter or Ammeter, as they can give advanced warning of developing electrical problems.
So I added an LED 12 Volt Power Monitor to an existing blank lower dashboard switch plate (FBV000090PUY £6.46 if you need another one), using the Velleman 12 volt Car Battery Monitor Kit MK189 which cost £4.21 + vat from sources such as Quasar Electronics.
Alternately a blank upper binnacle switch plate (FBV000080PUY £4.74 + vat) may be used, if no vacant / blank lower dashboard switch is available. The blank switch bodies are the same, but with different clip-on front panels.
I drilled a 3mm diameter hole in the centre of the blank switch plate and fitted the finished kit into the switch plate body, which is a perfect fit, just make sure you cut the 3 LED legs to the correct length.
I took an Ignition Switched 12 volt power feed from the Passenger Compartment Fuse Box, connecting into the lowest relay socket using male spade connectors (R211 V8 Engine Ignition Coil Relay).
(This relay is missing on TD5 D2s and so makes connecting to the vehicle power rails easy, Earth to relay connection pin 86, and +12 volt to relay connection pin 85), protected by Fuse F24 10 Amps.
On V8 models, any other dashboard power connection points will do. The dashboard photographs also show the Land Rover additional switch housing AWR3330LNF £12.71 + vat, which replaces the Ash or Coin Trays.
The Kit Bi-Colour LED shows a Steady Green for Battery OK. Flashing Green for Battery charging. Steady Red for Battery low, and Flashing Red for Battery overcharging.
Although the 3mm diameter Bi-colour LED looks bright in the photograph, it is not too bright at night, matching the green background dashboard illumination.
It is very accurate, as if I switch on both front and rear heated screens, together with headlights at engine tick-over, the LED changes from flashing Green to steady Red.
If I raise the revs very slightly above tick-over, the LED changes to steady Green, and then back to flashing Green. Luckily I have not seen a flashing Red display yet (battery over-charging).
