Complete loss of electrical power - 1991 Pontiac Bonneville

A lack of power in a 2005 Mazda Tribute could stem from various issues. Here are a few potential causes to consider:
Battery: If there's no power at all, start by checking the battery. A dead or faulty battery could prevent the car from receiving any power. Check the battery connections for corrosion or looseness.
Alternator: The alternator charges the battery while the engine is running. If the alternator is faulty, it might not be providing enough power to the car's electrical system. This could result in a loss of power.
Ignition Switch: A faulty ignition switch could prevent power from reaching essential systems in the car, leading to a complete loss of power.
Fuses and Relays: Check the fuses and relays related to the vehicle's power system. A blown fuse or a malfunctioning relay could disrupt power flow to various components.
Starter Motor: If the starter motor fails, it might prevent the engine from starting, resulting in a complete loss of power.
Fuel System: Insufficient fuel supply due to a clogged fuel filter or a faulty fuel pump could cause the car to lose power.
Electrical Issues: Wiring problems, such as damaged or corroded wires, could interrupt power supply to critical components.
Given the broad range of possible causes, diagnosing the specific issue might require a professional mechanic's assistance. A thorough inspection and diagnostic test using specialized equipment can pinpoint the exact cause of the power loss in your Mazda Tribute.

Sounds like the idle speed of your car is too low, then the alternator cannot produce enough voltage for any electrical devices. When idle speed is normal or much higher, power will return to normal very fast. It may be that the idle air control valve is dirty or defective.

Alternator would be the first part that I would suspect to be the problem. The battery, then an intermittent short in the electrical wiring would be the next place I would check out. Also check to make sure that the wires are securely tight on the battery too.

What happened before this ? Did you make any changes? Did it just die or it happened after it was parked a while. How did you get into the car ..with the key or power lock operation.. Give me more information.

bad diodes in alternater

I presume you experienced a loss of full power but had enough to get home. The check engine lamp came on too?

It seems your engine is in limp mode due to a possible over boost pressure . The ECU runs the engine with reduced power after an over boost is detected. If you cycle the ignition key and power comes back, this is most likely problem.

A fauliy N75 solenoid, with three small bore vacuum hoses and an electrical plug/connector, is possible cause .

This over boost can be caused by sticking vanes inside the turbo .

Have it scanned and read the codes. Code P0234 will be set if over boost occurred.

loose or poor contact to battery terminal

this is usually caused by a break in power wire right at the door janb inside of rubber accordian boot

Check your backup lights (reverse lamps) make sure your wire connections are tight and look forn worn wire sheath that may be allowing and unwanted electrical ground
