May not be related and jsut conicidence but anyway..

Guy's can anyone help on this please.. I am stumped!

I decided to fit a new turbo timer I had keying around.. Old HKS one.. So I bought a new HKS harness to make life easy. When I went to fit it I found there was already a harness there but it had been cut about a bit and also seemed to be wired to some relays? The old timer was not HKS but had the same plug. It also had an auto timer function so I am guessing the relays and bits may have something to do with this, altough there is a big green one which looks factory? Also the car has remote start altough I have never used it as I don't have the alarm master key to set it with. Maybe they are to do with that?
I tried te timer on the exisitng harness and it lit up but dd not power down the car. On trying to remove the existing harness I could not trace all the wires as they appeared to join into the main loom and I did not want to risk cut anything I shouldn't so I just plugged the new harness in line with this to the back of the ignition barrel.
Connected up the turbo timer and ran the car. went or a drive.. came back ignition off and the car kept running.. Great.. Until it didn't shutdown! So I tried to turn the timer off and the car kept running still.. Then I put my head under the dash and unplugged the timer from the loom. Car still ran! In the end I had to pull the negative terminal off the battery. Can ran for a few seconds (which paniced me) Then stopped!
So I pulled the new harness out and turbo timer. I noticed the new harness had two green wires that were spliced together accoss the main part of the loom where as the other one was not joined in this way? The two wires ran seperately It rings a bell reading that they are suppose to join? Anyway.. I connected the battery back up and started the car and noticed I now had the battery charge light on and the oil pressure and temp wanring lights! (guages were reading normal) If you revved the engine it dimmed down and would go out with enough revs After some searching it appeared the alternator must be damaged.. Maybe from when I pulled the battery terminal? I pulled the back off a spare alernator I had with some fin damage and swapped this onto mine. Started the car.. Light went out after about 2 secs. Fine..
Drove the car today and I got about 2 miles down the road and the alternator light was on agaan along with oil pressure and temp wanring lights but in addition came on the ABS warning light?
This time revving the engine did not dim the light out either?

The battery has gone flat a couple of times recently in the cold weather where the car has not been used but it's been charged up and appears to have plenty of guts to spin the car over and start it? Saying that I did notice today that the windows were very slow going up and down?

Can someone please help and let me know what's going on? It's really trying my patience now!

Thank you

Damn that was hard to read!

Sounds like your alternator is failed/or is failing. Does the car start right up, or do you have to jump to start it? Do you have a power fc? If so, you need to look at your battery voltage.

+1 on either alternator or wiring got f'ed up. Run the car, for a bit, does the airpump go on and off alot (clicking noise) and is the alternator hot to the touch?

Thanks Guys,
I appreciate that was hard to read! I thought that writing it..

I was going to test my battery and alternator with a volt meter tonight but it was dead again! After only 4 days and a 4 mile drive for which I had the alternator light on for 3 miles shes dead again.. Could it just be a knackered battery. It's been cold here and the battery went competely flat after a week sat in snow. Had also been sat not long previously and went flat.. I guess the whole turbo timer things implies it's more likely some damaged wires or two dudd alternators I have. Hopefully I can get a new battery and test it later in the week. I really hope it's not the wiring.. How on earth would I find the fault.. Would a live short it out and cause the problem I am seeing? Is there any relay on the ignition that could cause this problem?
I am on a single turbo setup so no Airpump for your info and have a power FC but no hand controller!

Any other thoughts let me know.

Cheers
Lee

Your alternator is not charging your battery (duh) - youe either have:
: a bad alternator
: a bad battery
: a wiring problem in the charging circuit
: some combination of the above
