Intermittent no start.

First, let me say that my blod pressure is through the fucking roof.

My 86 is being a world-class C***. Yes, that's a capital C.

Anyway, the issue.

I drove it to work today. Worked great. Park it in the driveway.

I come home a few minutes ago, and I need to move it to get a car out of the garage. Put the key in, turn it. The dash lights up and the digital voltage gauge I have reads 12v. Turn the key. Everything goes dead.

Hmm, it usually starts when it says 12v. In fact, it always starts when it says 12.

Check the battery with a voltmeter. 13.6v.

Grounds all attached, new battery cables, good connections.

Dead. Totally dead.

And to top it off, as I am pushing it up into my garage the small rear emblem falls off into my hand.

Fuck this thing.

Every time I want to fix something, or take it for a drive it shits out out on me, and it's just enraging. I have a 2000+ pound paperweight festering in my garage.


AGh.

There, there. *pats Palmy on the head*

It's just jellus of the Miata. You should sell the Miata.
Wait wait wait let me get my c900 in there first.
Have you checked the starter or ignition switch? I have an extra of each if ya need 'em.

If the dash lights came on, I'd assume the ignition switch is fine.

Starter solenoid died perhaps?
I turn the key, hear a click, and everything goes dead.


If testing something like that involves a hammer, I am all about it at this point.
It seems to come to mind a certain cable grounding out on your car not so long ago? That one is a ok? I think it was the positive cable by the alternator? I feel the same way about my cars lately
That was wrapped, and re-routed. I even replaced the battery end, and cleaned the other end with sandpaper, along with where it mounts.
Maybe a bad starter? It does happen. I would also take out a test light, and check voltage at various things in the engine bay. Easiest place to start.

Anyway, it's probably acting like a paperweight because you don't drive it enough! It's something like Aretha Franklin said, "If you want a do right, all day woman, you gotta be a do right all night man." Sort of.
I was driving it to work 2-3 days a week, and then this started, so I stopped.

I'll start looking at the voltage. I'll have free time for that in oh, a week and a half or so.
Hey, I'll actually buy it this time if you want to sell it.
I have been thinking it over for the last few months actually...
You try swapping/testing/jumping your battery? Maybe it's an internal short in the battery.
I have had quite a few that were in the connection between the fuse box and the inside wire harness. The pass through there. Yellow wire. Large one. Can't remember which of the 3 connectors it is though. Usually burned. Just run them through an empty hole and solder them.

"C900"?

I know the feeling. I've been driving my 900 and there is a drain on the battery somewhere. If I drive it daily it's fine because the alternator charges it back up, but if I leave it for a few days it's dead. Erk. Hope you fix your issue before giving up and selling it to Saabeh.

I only want to buy it so I can race ViggenLuca. I need to learn how to push the limits beyond my limits.
:lol::lol::lol:
Makes perfect sense.

If the starter/solenoid was bad I suspect the dash lights would stay on, like after usual unsuccessful start...

What do you have to do to get the power back on?
This sounds like you are loosing contact under load. Could indeed be bad battery even though it shows decent current at first. Have you tried jumping it yet?
Have you tried to monitor battery voltage as you try to start it?

Mine's doing the same thing. I keep a jump box in the trunk though, and park on hills whenever possible.

A battery draw should not he hard to find. Hook up an amp meter between the battery + & the + cable. Keep the car "off" and if you have a draw, you will see amperage bleeding through. Start pulling fuses, and you will eventually find the one that it is when you see 0.00 on the multi meter. What ever it is, you will know what it is then. At that point, remove or replace the device that is sucking the power when the car is off.

As for palmers problem, there is contact loss somewhere between the battery and the starter solenoid. Become frustrated by an issue serves no useful purpose, and finding it should not be hard with proper diagnostics. If you honestly can't find it, get it towed to a competent shop, that sort of problem should be easily traceable and rectifiable. It will probably end up costing an hour of labor for "diag" and even if they don't fix it they could tell you what it is and then you can fix it.
