Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Tighten Tighten the screws to 1.6 N·m (14 lb in).
Thank you very much!! Sorry about the slow replies. PC is slow tonight. The schematics help a ton! And your advice will be taken. I'll check out the battery drain and let the meter stay on for quite awhile. It may be simply a bad factory stereo(after 10 years, I guess it's acceptable......)
Have a great evening!
FYI. After 20 minutes the current drain dropped below 0.3 amps. I'll hook the battery back up and make sure, but it looks like the radio was the only problem all along.
Caution: Batteries produce explosive gases. Batteries contain corrosive acid. Batteries supply levels of electrical current high enough to cause burns. Therefore, in order to reduce the risk of personal injury while working near a battery, observe the following guidelines:
Notice: Do not turn the parasitic draw test switch to the OFF position with the engine running. Damage will occur to the vehicle's electrical system.
Notice: The test switch must be in the ON position when removing the fuses in order to maintain continuity in the electrical system. This avoids damaging the digital multimeter due to accidental overloading, such as a door being opened to change a fuse.
Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.
Important: The power down timer will reset to 20 minutes if any wake up inputs are received by a Class 2 device (after the scan tool has put all Class 2 devices to sleep).
Important: From this point on, electrical continuity must be maintained in the ground circuit of the battery through the Test Switch J 38758 in the ON position or through the ammeter J 39200 .
If the fuse does not blow, the current is less than 10 A.
The ammeter can be used safely.
Important: If an ammeter other than the J 39200 is used, ensure that the vehicle does not have a high current drain that would damage the ammeter when connected to the circuit.
A drop greater than 10 milliamps indicates a possible short to ground.
No drop in the milliampere reading indicates the PCM or VCM is not drawing current.
Tighten Tighten the battery negative cable bolt to 15 N·m (11 lb ft).
