Voltage Reading

[akarol]

Well, I figured I'd use the voltage display mode since I have the 9500ix directly hooked up to my fuse box and I discovered that I'm ranging between 13.0-13.7V. Is that bad? Is it too high and can it cause damage to the unit. I heard the unit has a sensor that will notify you if the voltage is too high or too low, but I don't want to rely on that alone.

Thanks in advance...

13.0 - 13.7 volts is totally normal.

Are you taking the reading as the car is running? Also, that reading is just an estimate, not 100% accurate.

Here is an estimate of many cars voltage:

Key on not running about 12 volts

Car running about 14.1

Yup,
For the most part:

Car off: 12.3-4Volts
Car running at Idle 12.8-13.0Volts
Car running 1,500+ Above idle: 13.8-14.0Volts
(Especially if the car/alternator aren't brand new.)

Trucks are normally just a few tenths above those numbers.


Yes those numbers you see are 100% safe though, and that reading (as aforementioned) is only approximate.

Yep, I'm running around 14.1-14.3 when running (that's with U/D pulleys), and 13ish right after I turn the key off.

during these hot summers with the ac full blast on start-up my 9500 frequently shuts down due to low voltage. kinda annoying actually.

Thanks for the reply guys. I feel a lot safer now. =D

BTW, I love the ix. Just saved me from two LEOs under this overpass on the way to work.

Sounds like you either have corroded battery post connections, or a weak battery, or a weak alternator, or a combination of these issues.
