Battery Voltage Indicator Gauge

[CJ_GT]

Hello,

I am in the process of purchasing a 1990 GT 5.0 and the battery gauge seems a tad low to me. Does anyone know if this is a normal reading? Thanks!

- When driving, mine is at the “M”.

- When key on/engine off it is where yours is in the photo

Thank you, I had the person I was buying it from take the photo and it looks NOT to be started because there is no oil pressure so it would be the same as yours

The RPMs are at 2K though in the photo

Correction, they had it idling

Use a digital voltmeter and measure voltage at the solenoid to ground. What to do you get?

Mine typically points to the RM area when driving

Mine is at the "M" when idling and cold
with Key on engine off im just under the "A"

Fox gauges are notoriously inaccurate. I would have the alternator/battery tested before coming to any definitive conclusions.

Here’s my idle

Mine has 3g upgrade and reads just a tad above 5l5's

To let everyone know, there was a short in my fuse box causing the erratic gauge readings. I had to completely rewire the fuse box to eliminate this. At one point my tach and speedometer also went out but the rewiring fixed the issue.
