help!! i have no idea whats wrong..

[nfpgasmask]

well i cant help you much with the problem, but i can tell you that if your battery is putting out over 14 volts you amp will shut off to keep from blowing up....

test the alternator and the battery...those are my suggestions...

That's what I was thinking. Something is overloading the electrical system. I'm no expert, but I have a scanguage and mine always reads around 12v iirc. When I flip my roof lights on I see it go to like 14v or so. I have never seen 18v...

Good luck, Eric!

also check any connectors to the back of the alternator for corrosion. I had gremlins in a Trans Am that turned out to be corroded connectors and the corrosion was "not easily noticed". It would vary from overcharging to undercharging and back to normal charging as the electrical system tried to compensate for bad connections.

Check to see if your battery is warm to the touch and/or the sides are bulging out. You may have an internal short in your battery which can cause a lot of problems. It happens often with aftermarket batteries.
Hope you get it all worked out.

I had a similar problem in my Porsche. I replaced the alt/reg twice and it truned out to be a defective battery. I assume it was shorted internally and it was intermittent. Replaced battery and it's been good for over a year now.

Good luck, hope it ends up being something easy.

As well as above, i'd look at your amp, sounds like it earthed the +. Its more likely to be something you have added to the car thats gone wrong than something stock, imho. Something as simple as screwing the amp down and the screw touching the bodywork etc ?

But if it did earth the + then have you checked all your fuses out ??

Hi eric.
Most of us came to the same concusion,your issue is electrical,the ECM is also exposed to get damage if the right diagnostic isn't done right away.

If you had any electrical work done on the VX recently then is time look over for possible mistakes.

Good luck

Eric,

Sorry to hear about your troubles. I know it sounds hokey but the battery could be your problem (just like everyone else has mentioned). Just disconnect the battery after you have it started & see if the problem persists.
