something went wrong.......... electrical.....

hey peoples,
just need some advice or knowledge on a problem im having on my 89 tx3. well here goes, just had a sound system installed (amp, sub etc). anyways over the past few days ive experienced my head unit turning off when the volume goes to loud. tonight on a usual cruise the battery seemed like it was dying (lights going dim, blinkers to slow, horn dead etc.). ive now parked the car in my garage and it wont turn back on. although the car can be clutch started and turned on, however all electrical seems like its slowly dying. it was idleing a bit weird however at a stage during this (idles up and down). i have noticed the wiring used on my set-up is pretty thin and the fuse thingy looks gay and small, could this be the cause that started the problem? and wat could be the problem?. appreciate any info given.
cheers
ahmed.
oh and every time i turn the car off it wont turn back on  (has reds and all but just wont click over)

There is obviously something wrong with your ICE install. Try pulling the fuses for the system and head unit and see if this improves things. Sometimes you can get a power drain in a unit brand new. Change the battery for a new or known good one. If things are the same then something has gone wrong with the wiring and if the install was done by a professional, its time to get back onto them. Good luck mate.

that actually sounds like an alternator problem
your car isn't keeping charge with the ICE setup going. I know mine carked it slowly after I put in all my Stereo gear. Got a reco'd one, and she's all sweet now 
Hope this helps

Good thinking,
What are you using in your install? Its possible that its drawing too much power from your battery/alternator and flattening the battery. Depending on what your using, you might need to fit a powercap or uprated alternator.

I'd agree with the rest, alternator is on the way out. They face out gradually, providing less charge before they die. Adding the ICE to your car has pushed it that little bit over the edge and now it's not able to charge the battery and everything else in the car.
Go to an auto-elec, they'll be able to test if the alternator is shagged, or it could just be your battery, which they can also check.

This may sound dumb, but how clean are your battery clamps?
Just a thought...

Ermmmm its a Ford........
I reckon its the Battery/alternator or possibly the regulator, Im not sure what setup the tx3 has but it might be worth a look.
It could also be worth your while to change the cable on the alternator to something bigger, I had the same problem on one of my commodores I had and after changing the cable from this little piss ant cable, to 2 lots of 4 gauge cable, no drama's.
Remember, if you have heat in your wiring, it creates resistance therefore a voltage drop and when you try draw more current it creates more heat and more voltage drop.

From what you described here it sounds like the battery is good but your charging system is faulty.
When you turn your ignition on does the battery light on the dash come on?
Does the battery light then go out when the engine is started?
If the battery light on the dash has a blown globe the alternator won't charge. Also check that the alternator drive belt is tight and in good condition. You can also get a multimeter and measure the voltage at the battery with the engine running. This should be 13-14 volts depending on how flat the battery is.
If all else fails, take it to an auto elec on Monday.
Good luck and let us know how you go.
Brad

i think SIKPUPPY is right........ wen the car heats up thats when this probo starts, the car turns on perfectly, drives perfectly, but after a while of driving around it starts to play dead battery game. the battery however is fairly new (2mnths old). also i had changed the alternator belt on 2-3weeks ago. the battery charge light doesn't come on, and the globe doesn't seem blown (the globe turns on on reds). im heaps confused on this and it really sucks as my car is for sale and cant be sold until fixed! its only fair i fix it thanx heaps guys
