Hi guys!
Is it normal that my voltage drops whenever i turn the steering wheel?
I noticed this when i installed my HUD with a voltmeter in it.
on idle its 14+ on volts but when I turn the steering it drops to 14 below.

As opposed to the hydraulic power steering used in vehicles in the past, modern vehicles like the Mirage use Electronic Power Steering (EPS). As the name implies, EPS using electronic power and an electric motor to assist in steering.
The motors used in EPS systems can pull down a lot of juice, so the sag in voltage when turning the wheel is expected.
What pity on you said,
Electronic power steering motors are normally around 1hp.
The battery is suppose to act as a buffer for the alternator. If you are seeing a serious voltage drop/sag when steering. I.e high beams dim when steering you may have a bad battery.
please consider checking out my Mirage related youtube channel: https://www.youtube.com/channel/UC6c...IEViRFw/videos
The better question may be: can the draw of the EPS be adjusted (lowered) to increase weight/feel - which would benefit skinny OEM wheels/tires.
My 195s don't have this issue.
Please. None of the 2009 KIA RIO cars had narrow tires. A factory size 175-195 tire on a KIA RIO is not a narrow tire for a car that size. My ex-wife had a 2007 KIA RIO for a long time.
Power steering was invented in 1951.
"As early as 1953, there were already 1 million cars using power steering. This time, the public took an immediate liking of power steering, and driving would never be the same. By 1956, a quarter of all cars in America had power steering. And, by 1960, that amount would increase to more than 3.5 million."
Power steering was pretty common by the 1990s. Even several tractors from the 1960s & beyond had hydraulic power steering.
The EPS of the Mirage is not impressive for the current period. I agree that reducing it would help the driving dynamics of the car.

Lightweight FWD cars don't really need PS, & they may actually handle much better on the highway without it. I don't think the time period is all that important.
I think a cheap 1988-93 Festiva (paid $5,300 new) benefited from Mazda engineering (when it came to steering/handling).
If I had the choice of buying a new 1990-93 (became fuel injected 1990) Festiva or a current Mirage, I would pick the one with fewer features & more character.
