2006 ford exdedition, orange service light is on

the flashing orange light is the glowplug light that telling you there is a engine managment problem. you need to get the fault code out of the engine control module with a obd code reader to determine the cause but the common cause of the flashing glow plug warning is a air leak after the turbo charger

You would need to check the connections on the back of the alternator with a meter.
You should have battery voltage on the large wire and on the orange yellow wire.
The other two wires involve the engine computer which turns the alternator on after the engine starts.

You'll need to take off the top cover, 4 10mm bolts. You'll have to unplug and unbolt the 8mm bolt on each coil pack. Pull up the coil pack and plug boot. Each plug is down in the head, you'll need a 5/8" socket 6 inch extension and a ratchet, also an extend-able magnet is helpful. On some these motors you need to remove the fuel rail. The rear, passenger side plug is very difficult to get to.

orange would mean service engine, like the old orange colored service engine soon lights that are computer or emissions related. red would mean oil or engine problem. it's probably a motor symbol so we can dismiss ABS or other red brake light.

This is the check/service engine light. They will go off when the computer senses a fault such as bad sensor or bad electrical circuit. Most part stores will test the car by running an engine code diagnostic scan which will pinpoint exact problem area. Most shops charge $40 which is well worth it.

oil pressure light get the oil pump checked
