crazy speedo dials

[brundish24]

hi my speedo,rev counter,oil pressure gauges have gone crazy

the speedo reads about 15-20mph
the rev about 800rpm
the oil pressure reads about 4-6

and this is when the ingition is on and the car is not running what the hell is going on.

i did remove them and dismantle the cluster to take the faces off and change the bulbs to some led ones when i put them back in this has started when the car starts up it gos to about 2k revs it normally runs at about 1k when i tap the throttle it does work also i have half a tank of petol in it and it reads full? here is a pic hope the link works

The FD clocks are known to fail, you might need a new set of clocks

right i think i know what the problem is when i removed the dials i also removed a clifford alarm system and wired it back up with out a alarm fitted now i fort it was wired ok but today i put the battery on and accidently turn the lights on then i relised the keys are not in:2eek so must of wired it wrong as there is allways power as everything works now would this affect the dials also what wires do you think i have wired up wrong.

What happens when you start the car and did you take the needles off at all.

[brundish24]

i started the car and its runs havent taken it out as i need to put in my apexi in it and i did take the needles off.

[darknight7777777]

The reason I ask if they move when the car is running means the gauges are fine only you put the needles on in the wrong places. This happen to me when I was taking the orange of the gauges.

Take the needles of carefully.
Plug in the gauge cluster.
Turn key to on position.
Push the needles in correct places ie on 0 positions.
Turn key off and the needles should fall a little to resting positions.
Put the clear plastic cover back on

that\'s what I did and all mine are fine execept the fuel but that\'s because of a short on the wiring somewhere.

Regarding the alarm you wired the the wires the wrong way round, what model is the alarm I will send you a install PDF which could help.
