Q: How to Ensure Proper Maintenance of Battery Cables on a Mercury Mountaineer?
A: Prior to repairing or servicing the battery cables the vehicle must be placed in NEUTRAL position and set on a hoist. The battery needs disconnecting followed by removing the protective cap from the starter solenoid terminals and the terminal nut from the wire cable so you can tighten both to 6 Nm (53 lb-in) for reinstallation. The next step requires you to remove the starter solenoid positive cable terminal nut which has to be tightened back to 12 Nm (9 lb-ft) after installation. Disconnect the terminals beginning with the wire cable of the starter solenoid followed by the positive cable of the starter solenoid then finish with the nut of the starter motor ground cable terminal before tightening each one to 25 Nm (18 lb-ft). The service begins with disconnecting the electrical connectors from the power steering pressure switch and A/C compressor and oil pressure sending unit in sequence. The first nut removal allows you to move aside the engine front cover bracket for the battery cable while tightening it to 20 Nm (15 lb-ft) at reinstallation followed by second nut removal to expose the battery cable frame bracket which needs tightening to 9 Nm (80 lb-in) when reinstalling. Detach the battery cable harness locators from the front area of the engine before disconnecting the two generator electrical connectors. The technician should place the protective cover to the side and remove the nut to expose the generator B+ terminal before securing it with 9 Nm (80 lb-in) torque. Release the battery cable harness locator from the generator harness guide and open the BJB cover to remove its two tightened BJB nuts to 9 Nm (80 lb-in) during reinstallation. Take off the BJB terminal after disconnecting it then remove the nut to set the body ground terminal of the battery cable into position before tightening to 9 Nm (80 lb-in). First disconnect the battery cable harness electrical connector at the battery tray before removing the two battery cable harness locators from their position and the battery cables. The procedure for installation follows the steps in reverse order.
Q: How to Ensure Proper Functioning of the Battery Cable in a Mercury Cougar?
A: The battery cable servicing requires the removal of the engine air cleaner as the first step. Before working with the positive battery cable you must connect to a back up power supply then disconnect the battery ground cable first followed by the positive cable before waiting for one minute to avoid air bag activation and injuries. Start by taking the battery cable terminals from distributor plates and then unplug the starter motor solenoid electrical connector. The first step to disconnect the battery begins by cutting the cable tie that holds the battery cable to the battery tray. Then disconnect the ground cable from the transaxle housing and follow by detaching the positive battery cable from the engine wiring harness. Remove the cable tie at the engine wiring harness. Lift the vehicle into position before you disconnect the electrical connectors of the starter motor. Continue by lowering the car. Start by removing the shorting bar cover followed by disconnection of the positive battery cable before proceeding with removing the battery cables. Engineers should follow the opposite sequence of removal steps when installing the battery although vehicle behavior may become abnormal during this period since the vehicle needs adequate time to learn its adaptive strategy through driving longer distances.
Q: How to service and repair the battery cables for the 2.5L engine on Mercury Mariner?
A: Service technicians should begin the repair of battery cables for 2.5L engines by disconnecting the battery. You should first remove the air cleaner assembly and generator B+ terminal nut before tightening the nut to 12 Nm (106 lb-in) when reinstalling it. Initial step is to place the generator B+ terminal cable aside and then remove the generator harness retainer. Follow this service procedure by first removing the starter solenoid terminal cover then uninstalling the starter motor positive cable nut and re-tighten it to 12 Nm (106 lb-in) during installation. During installation tighten the starter solenoid wire nut to 5 Nm which equals 44 lb-in. The mechanic should set aside the starter motor terminals before unfastening the battery ground cable bolt that requires a torque setting of 25 Nm (18 lb-ft) when reinstalling. Disconnect the pin-type retainers located on the left rear and middle of the intake runners and front of the engine with the clip retainers also removed from the right and left front of the engine. Secure the left fenderwell body ground terminal bolt at 9 Nm (80 lb-in) during reinstallation. Open the Battery Junction Box (BJB) cover first then take off the BJB terminal nut while tightening it to 10 Nm (89 lb-in) during reinstall and set the terminal aside. First disconnect both the BJB electrical connector and battery cables retainer clips from the battery tray before taking off the battery cables. The process ends through following the reverse order of what was used for removal while reinstalling.
