How many volts does a GMC Yukon have?
This is common on large GM Vehicles: Some customers may comment that the voltmeter is fluctuating between 12 and 14 volts on their full size pickup or utility vehicle. Starting with the 2005 model year, light duty full size pickups and utilities are equipped with a new Regulated Voltage Control (RVC) system.
Is there a charger problem on my Yukon XL?
Discussion in ‘ General Discussion ‘ started by 01YUKXL, Sep 3, 2010 . I saw a similar post on this but can’t locate it… My 2001 Yukon XL is having a charging system problem.
How to diagnose battery Guage on a GMC Yukon?
The engine computer (ECM/PCM) will ramp up engine/generator speed in small steps so engine speed variations are not noticeable to the driver. For diagnosis of the battery and/or the generator, refer to the appropriate Service Information (SI) or Corporate Bulletin Number 05-06-03-002C.
What causes the idle voltage on a GMC Yukon?
Items that affect the vehicle’s electrical system current and voltage at idle are the number of electrical loads being used, including add-on accessories, and extended idle times.

When to supplement the battery in a GMC Yukon?
With enough electrical loads “ON”, it is easy to exceed the generator current (amperage) output when the engine is at an idle of 600-700 RPM. This is a normal condition. The battery supplements for short periods of time.
What’s the voltage regulator on my Silverado truck?
The truck now has 85,000 miles and on my way to go camping (about 125 mile trip one way) the voltage regulator dropped to around 11 or 12. Of course I panicked and found the nearest parts store to check for a bad alternator, they said all good no problems.
What happens to the generator in a GMC Yukon?
When high current loads (blower, rear defogger, headlamps, cooling fan, heated seats, power seats, electric “AIR” pump, or power windows) are operating or cycled “ON”, the generator’s voltage regulator can delay the rise in output. This effect, usually at lower engine speeds, can take up to ten seconds to ramp up the generator output.
Why are the lights dimming on my GMC Yukon?
Dimming of the lights is an indication that current is being pulled from the battery. If the battery is in a low state-of-charge (discharged condition), the driver will notice a more pronounced dimming than a vehicle with a fully charged battery. 2.
