How do i replace the negative battery cable on the 2006 cadillac cts?

This sounds like it is trying to "Short Out". Turn off all the power to the chair and re-check your battery connections.
A "Short" is where the electricity is trying to flow the Wrong way around the circuit. This will badly Damage you batteries if you keep trying to connect them.
When connecting batteries together you ALWAYS connect a Positive (+) to a Negative (-). NEVER Positive to Positive or Negative to Negative.
Start at the Negative wire, connect it to the Negative terminal on the first battery, (Battery One). Then on Battery One connect the Positive terminal to the Negative terminal on Battery Two. You now connect the chair's Positive cable to the Positive terminal on Battery Two.
You should get NO sparks. Carefully turn on the chair's power. The batteries should NOT spark and should NOT get hot quickly.
**CAUTION** If it does spark or get hot quickly after you have done this TURN EVERYTHING OFF and disconnect the negative cable. This means there is a problem somewhere else in the chairs electrics.

STARTER REPLACEMENT (ENGINE ELECTRICAL) Document ID# 688149 Starter Replacement

Removal Procedure

Important: This vehicle uses the PG260 F1 starter motor. The starter motor is serviced only as a complete unit.

1. Disconnect the battery ground (negative) cable from the battery. Refer to Battery Negative Cable Disconnection and Connection.
2. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.



3. Remove the starter motor BAT terminal nut and electrical leads.
4. Remove the starter motor S terminal nut and electrical lead.
5. Remove the torque converter cover. Refer to Torque Converter Cover Replacement in Automatic Transaxle - 4T65-E.



6. Remove the starter motor bolts.
7. Remove the starter motor.

Installation Procedure

1. Install the starter motor.
Notice: Refer to Fastener Notice in Cautions and Notices.

2. Install the starter motor bolts.Tighten:
   Tighten the starter motor bolts to 47 [n-m] (35 lb ft).
3. Install the torque converter cover. Refer to Torque Converter Cover Replacement in Automatic Transaxle - 4T65-E.



4. Install the starter motor S terminal electrical lead and nut. Tighten:
   Tighten the starter motor solenoid S terminal nut to 3 [n-m] (27 lb in).
   
5. Install the starter motor BAT terminal electrical leads and nut. Tighten:
   Tighten the starter motor solenoid BAT terminal nut to 10 [n-m] (89 lb in).
   
6. Lower the vehicle.
7. Install the battery ground (negative) cable to the battery. Refer to Battery Negative Cable Disconnection and Connection.

Disconnect the negative cable from the battery, then go inside your car and press the break pedal for 30 seconds. That should drain the extra power and reset your computer.

Disconnect the battery and clean both terminals. Wait about 10 minutes before re-connecting battery terminals. That will reset your car's computer. Should start if there is enough juice in the battery. If you hear a clicking sound when you turn on the engine it means your battery is too low to turn the engine and probably means it's time for a new battery. Get someone to give you a boost and it should start fine. Your battery is probably original equipment and more than 8 years old. Thats about maximum life expectancy for a battery.

for one, your starter / solonoid unit is in need of attention, even replacement ! it stays engaged, hanging up, solonoid could be going bad, replace the entire unit. check the positive & negative battery cables sometimes they need replaced ! think about it, a cable as big as they are, you would'nt think they would need replaced , but maybe they do ??? just a thought ! alwasy clean battery terminals , put vaseline on them before reconnecting the terminals, it will keep them clean & corrosion free ! clean off battery also, remember its acid, so don't get any on your clothes !

Fist thing to try for a quick fix would be to clean terminal posts. It's a pretty easy do-it yourself project.

To do this find where your battery is connected, remove the negative battery cable (black with a - sign) then remove the positive terminal ( red with a + sign). Clean both the terminals and cable end with a wire brush. If heavily corroded, use a paste of water and baking soda on a toothbrush to scrub then rinse off. This may bubble and foam when it comes in contact with the corrosion. After you've rinsed off any remaining baking soda, replace the positive terminal first and tighten, then replace the negative terminal and tighten.

If that doesn't solve the problem, I'd have the alternator tested and replace if necessary.

Good luck,

Disconnect the negative cable from the battery terminal...Locate the IAC valve on the side of the engine, near the intake...Remove the electric cable on the back of the IAC valve. Remove the screws that attach to the IAC valve and set them aside...
Pull the IAC out of the Cadillac DeVille and replace with new valve...Connect the IAC valve to the wire and reconnect the screws. Turn the screws so that they are completely tightened...Reconnect the negative cable to the battery and start engine to test valve.

Good luck, i hope this helps.

Use a wrench to remove the negative and positive battery cables: They are clearly labeled "+" and "-." Always remove the negative cable first, as this isolates the power to the metal parts of your car. Tuck the cables away from the battery as you don't want them to accidentally touch a battery terminal when you're wiring your alternator.

3

Locate the alternator terminals. There are two: one marked "live," "pos" or "+" and the other marked "neg," "field" or "-."

4

Locate the two cables. The positive (red) cable goes to your battery via a wire loom or harness. The negative (black) cable attaches to a metal part of your car.

5

Check how the cables attach to the alternator terminals. Some connect using eyelets that hook over the terminal and tighten with a bolt; others connect by inserting the wire under the terminal and tightening a bolt.

6

Loosen the two bolts using a suitable-sized wrench or, if the cables connect using eyelets, remove the bolts.

7

Insert the exposed end of the negative (black) cable under the loosened bolt on the negative terminal of the alternator, then tighten the bolt. If the cable has an eyelet, hook it over the terminal and screw the bolt back in place and tighten using a wrench.

8

Insert the exposed end of the positive (red) cable under the loosened bolt on the positive terminal of the alternator, then tighten the bolt. If the cable has an eyelet, hook it over the terminal and screw the bolt back in place and tighten using a wrench.

9

Replace the positive battery cable on the positive battery terminal using a wrench. Replace the negative battery cable on the negative battery terminal.

Please clean and tighten your battery terminals. Also make sure the other ends of these cables are tight to the engine.
