Firmware Update and Battery Voltage
 

On my firmware updates it says my battery voltage is 10.4. Is that normal or in the acceptable range. I ask this because I can let my car sit for no more than two days without the battery going dead. Then after I jump start it I have to remove and replace the fuse in my radio.

Is 10.4 an indicator of an issue?

Uh, sounds like you have something draining the battery. So yeah, that would be an issue. if I were you, I'd pull the fuse from the radio and see if it still goes dead after a couple days. Of figure out where the current draw is coming from.

Thanks I'll do it today.

Can I pull the really annoying buzzer, that indicated the door is open. I pulled a fuse once, and it helped with my battery issue, but my horn wouldn't work. Is their a relay, or maybe even an actually buzzer I can remove. It looks like the car might have had an alarm at some point, so I'm wondering if the buzzer is factory, or was altered when the alarm when in.

you can just pull the plug from the buzzer. Open your door, get your head under the dash, and feel around for it. When you find it, pull the plug out and it will stop. It is the first thing I did with both of the miata's ive owned ... why on earth mazda made it so freaking annoying is beyond me.

That was actually kind of cool, thanks.

Saw one on here earlier, it's pretty slick :) First google hit has all the info you need to find the buzzer, good luck.

The battery solution was amazing simple. I bought a battery tender because I was tired of having to pull my battery. I set the car on trickle and left it for a couple of days. When I finally remember to check it, I decide to start it, and see if the charger worked. Not only did it work, it started better than it did when I jumped if from my jeep. For the next week when ever I was going to let the car sit for more than a day I put in on the trickle charger. Then I had a really long weekend, I planned to drive the miata, so I took it off the charger, but I ended up taking my jeep because I could put my bike in it. Almost a week later I went back to the miata expecting to have to jump it off, and it started up just as it would if I had used the charger.

I found out my car hadn't ever fully charged the battery. Letting it get a complete charge on the trickle took care of the issue. I haven't had this issue in over a month. Just wanted to give an update.

My issue has been fixed.

BTW the charger was a Harbor Freight Special by Chicago, Its cheap but it clearly worked.
