Not Starting.

[Wrighty_1988]

Hey, yesterday i went to start my car as usual, put the immobiliser tab near the place where it turns off then went to start the car it was clicking like crazy and the rev gauge was going up? The clicking sound im almost certain was comming from around the key area. So i first thought the battery, went and got a battery tried to start it it did the wierd thing for 2 secs then started up fine and ran fine. Came out again today to use it and it was the exact same clicking and rev gauge thing. Then it seemed to get slower the clicking, got a lift to colege when i came back the battery was completely dead nothing was on.

Only thing i can think of it that i have recently put a new headunit in and i always turn it off and take the fascia off but i have also added a amp and sub and the amp remote wire is wired upto the ACC wire on the wires behind the headunit, have i wired it up to the wrong one and its causing the amp to be powered up all the time ?

Any views will be welcome.
Thanks for your time

Just looked at my remote wire and it traced back through the connectors to the remote/antenna wire so it isnt the remote wire

Does sound like a battery problem. I'm thinking the clicking is the starter motor not having enough juice to turn but i've not had the rev counter flick as well while its doing that.

The obvious thing to check is the stereo install, i'd experiment with disconnecting the power from the amp itself and work on from there. Getting a multimeter, if you haven't already got one, is a great investment. First thing i would do is turn the ignition off then check everything to find out what's live and what isn't.

Also try just giving the battery a really good overnight charge. Batteries often get low over winter with all the heaters and lights etc. so maybe adding the amp has just pushed it over the edge?
