Tacho seems to be draining power...

[9898989]

I have a aftremarket tacho hooked up to my vk and it seems that it is draining my battery power/charge

Last week my car was left for 5 days when the earth wire was NOT connected to the tacho and it started just fine...

But this week I hooked up the earth wire to the tacho and the battery was drained when I tried to start it this mornin after 4 days of just sitting there

Any ideas???

Aftermarket Alaram still was operational but just wouldnt start!!!!

how is it wired up? To existing loom or have new wires been run?

This is my setup mate i have a speco 03 model, green wire to coil, red to 12v accessory and black to a screw on my chrome strip. The tacho will only turn on when she starts. "sometimes it doesnt show, but if u move your key back 1mm it might"

Connect the 12V wire up to your ignition switch, so the tacho only turns on when you turn the key.

i have wired it so that it only works when the ignition is on

Then it's not your tacho guage.
