please help
I have a '87 924s that I recently installed some audio goodies into.I wired in the new HU and single 10.I did everything right, I soldered everything,electric taped it,the battery wire has a fuse,etc. I believe i played the amp to long with the car off and might have had it a little too low. I went to start it and it would turn over once or twice and I would have to turn it all the way off again. Long story short It fired up and i let it run for 10-15 minutes.The amp and and radio were on,But I didnt have anything playing.I tried to start later and no cigar, not even trying. the only noise sounds like its coming from the fuse/dme area and there is some sort of noise from the back too i think.The battery isnt even a month old and i disconnected and cleaned the cables and let the battery charge over night.I said my prayers and turned the key,same story different day.The onlything that dims when I turn turn the keys is the headlights which I think is normal,and i disconnected the amp and still nothing,please someone be my hero and help me out it kinda has me beat

do you get any clicking from the car when you try to turn it over? If not, the battery needs to be checked -load tested or with a hydrometer. If it is totally up there's a good chance it could be the starter..Sometimes they will give a click if the solenoid is OK, but most of the time nothing will happen at all, making one think it's the battery.. Are your grounds good and clean? How about the battery connections themselves? Corrosion on the terminals is a big no-no as far as current is concerned. no green grungies on the cables or the terminals..if you disconnect the terminals, the negative comes off first and goes on last..hope this helps some..

so the clicking from the relay and fuse box will be the fuel pump relay. The sound at the back of the car will be the fuel pump.
My first thought would be to disconnect the battery cables and hook directly to another car with cables. I don't consider this jumping the car. It's taking your battery out of the equation all together. If that doesn't work try pushing the car and popping the clutch. It will take the starter out of the equation but be ready to push it home. The 944 gearing and compression will mean you need to be at a good run when you hop in. Key already on, throw it in first, accelerator to the floor, let the clutch out. Leave the accelerator to the floor until you get to at least 2500 rpm so you know it's going to keep running. It will give a pretty good buck as it tries to catch.
I have had had more than one new battery end up with a bad cell after a week or two.
If if none of this works you may have some other issues that need diagnosed.

You'd do better with a more informative subject line. Not everyone reads every message.
Has the battery been tested?
What does it mean to "jump the starter"?
If you push start the car does it run? What is the voltage running/not running?

You said the headlights dim when you turn the ignition on. I'm guessing that the terminals for those two smaller wire's going to the batterys positive terminal are the cause of the problem being you was just doing something right there.

Okay, this is what you need to do. With the back wheels off the ground, in neutral and parking brake set, have a helper hold the key in the start position. Go under the car with a voltmeter. Place the ground lead on the starter. Place the positive lead on the large battery terminal on the starter and note the voltage. Next place the positive lead on the smaller "S" terminal on the starter and note the voltage. Post those voltages so I can point you in the right direction.
