November 6th, 2009

Jeep Grand Cherokee Battery Cable Harness The following schematic diagram shows Jeep Grand Cherokee Battery Cable Harness. The Grand Cherokee Battery battery is made up of six individual cells that are connected in series. Each cell contains positively charged plate groups made of lead oxide, and negatively charged plate groups made of sponge lead.

A normal vehicle electrical system will draw from 5 to 25 milliamperes (0.005 – 0.025 ampere) with the ignition switch in the Off position, and all non-ignition controlled circuits in proper working order. The 25 milliamperes are needed to supply Powertrain Control Module (PCM) memory, digital clock memory, and electronically tuned radio memory.

2003 Lexus ES300 Power Transistor Circuit

November 5th, 2009

lexus es300 power transistor circuitThe 2003 Lexus ES300 air conditioning control assembly controls the blower speed by varying the voltage at terminal BLW which applies the base current to the power transistor. The air conditioning control assembly also monitors the power transistor collector voltage at terminal, VM to control blower air volume precisely. The following schematic shows the 2003 Lexus ES300 Power Transistor circuit and wiring diagram. The system composed of heater main relay, blower motor, extra-hi relay, lo resistor, A/C control assembly. (click image to enlarge)
