A few weeks ago i posted seeing if everyone had a constant of 13.5 voltage, NOW im reading 13.2 constant with the car on. Is this normal, sometimes its at 13.1 and others 13.7 but for the most time is 13.2
Is there a reason you are monitoring the voltage? Are you having battery or starting problems? If you're having problems, what are the symptoms?A few weeks ago i posted seeing if everyone had a constant of 13.5 voltage, NOW im reading 13.2 constant with the car on.

I'm curious. Why did you swap out the stock battery already?Mines averaged 13.2V. Both with the stock battery and later I changed it to a Die Hard Platinum. Still the same. My stock panasonic battery was/is still fine. just sitting on my floor in the backyard.
I'm pretty sure that the FJ has more electronics, sensors, and wiring then the Acura has. All these extra goodies that came with the FJ, offer more resistance to the electrical system, resulting in a lower voltage reading based on these extra resistances, but as other posters have already mentioned, ~ 13VDC is quite normal for the FJ.I just noticed, before the Fj i had a 2003 Acura Mdx and voltage was always at 14, And noticed how low the Fj was at. NO problems Yet, Just curious to see what you guys normal had it at, i did observe thou, in the mornings the first start of the day, Its around 13.9 for about 30 mins then drops to 13.5 then maintains at 13.3, sometimes even lower as 13.1 Very odd IN my opinion, When most cars are at a steady 14.
Just after you start the FJ the alternator will have more load on it as it works to "top-off" the battery & replenish the power used in cranking the engine. After running, (and charging) for a little while the battery regains its complete charge & the load on the alternator is reduced. At this time the regulator will dial back the alternator's output which, depending on its design, may result in a measurable drop in voltage. This is normal operation & should not be a concern, good luck.I just noticed, before the Fj i had a 2003 Acura Mdx and voltage was always at 14, And noticed how low the Fj was at.
