WTF! Voltmeter screwy?
So I just finished installing my appradio 4 and it works great. Nice day out, so thought I would take car out for a bit of a shakedown run. Everything working well. Just about coming to the end of the ride and I notice my voltmeter looking like the first pic. However, NO BAT light. Then I shut motor down once in the garage and the voltmeter is in the position of the second picture. The radio works fine. Everything works including Siri, Maps, CarPlay etc. I am getting a staticy noise coming from the passenger side front. It even did a series of clicks which got progressively quieter then apparently stopped.

Re: WTF! Voltmeter screwy?
I'm posting second pic here because for some reason, I can't post more than one pic per post.

Re: WTF! Voltmeter screwy?
Just went out and checked digital readout and it shows normal voltage. NOW w Motor running the meter is reading correctly. W Key Off, its still off the scale.
Bad Voltmeter? |

Re: WTF! Voltmeter screwy?
According to FSM page 8A-82-0 the instrument cluster voltmeter reads fuse #27 voltage directly across the line to ground. If a poor connection is not involved then the gauge is probably suspect.

Re: WTF! Voltmeter screwy?
Dom if the voltmeter turns out to be the problem I highly recommend Batee.com for the repair. GC

Re: WTF! Voltmeter screwy?
The + feed is common to all the analog gauges so if you had a voltage issue the other gauges would also beacting up.

So Phil, you are confirming its the volt gauge itself. And oddly now, the gauge is reading correctly when the motor is running whereas it was not when I drove the car yesterday. |

Dom, Just for you,  I pulled my cluster PC board out to take some pix that show what I mean.The fact that ONLY the volt meter is being intermittent, suggests a connection issue, either external (which might be either external or internal to the meter). Both the common connection (run) can be seen, as well as the mechanical contacts for the individual gauges. (I suggest you might consider pulling the board too and service all the mechanical connections and spray on some electrical cleaner. Just a thought.)
