i have a 92 corvette, 67000 miles like mint,was driving about 1 month ago and died on me, got towed home. battery would not charge. i got a new battery still wouldnt hold. put in a new alternator and still wont run will act like wants to start then blank. i checked all my fuses, made sure my under hood lights werent on"i even unplugged". checked all interior lights/seats taillights etc.. nothing seemed out of ordinary. i am reading 14.1-14.7 volts all day long. my question is there a power drain or relay i should check? any idea wat else could be?
also last time i got running ran for 5 mins and shut off went to start and everything went out. noticed a wire that went to the center of my block in front fell off but still dont think that fixed. pls help me im out of work, and cant rlly hire someone. and tired of seeing it sitting collecting dust.

 

nevermind.

 

Ground issue?

 

Welcome, sorry to hear you have this problem. Once the power goes away so does your programing and the car can run like crap if it is in marginal tune has components issues [Codes] ?

Be advised Electrical troubleshooting theses cars is not simple and is not easy. Diagnosing electrical problems without tools, a little electrical understanding, and schematics is going to be a real hit and miss proposition.

We'll see what we can do?

Get a Volt meter that will read 12v or a neaon lamp tester .

Use the voltage setting for 12v or more and go hunting

Take the side panel covering the battery. If your model is like my '89, you'll see a " jump start stud " below and behind the battery. Almost all the cars circuits get power at this point, from the battery.

Disconnect all and take the meter or lamp and jump between the + battery terminal and each of the wires that had been connected, individually .

The one that "lights Up" will be the culprit.

Reconnect only the one that lights up and go to the fuse block.

Pull the fuses one at a time and "read " from the fuse stabs to ground
[ and good metal frame connected part]

That will tell you that the wire you found powers the fuse block

The read across the two stabs . When you have a circuit you might just have the problem .

You can then repeat this process at the fuse block.

PS: FILL OUT YOUR PROFILE!!!! Where are you? Help might be down the street or just a block away.

 

That's what I was thinking, esp. with that "wire" that's not connected.

But, what do I know?

 

thx yea im going to borrow a meter to check for any draws. im hoping that is it. im still wondering on the wire that plugs right into the block near the belt tensioner. srry to bother but also wondering is there a relay to drain power i think as a safety feature?

im in pennslyvannia near lancaster

but yea imma try to get the volt meter tomo check fuses hopefully if this storm passes.

 

hmm looking over reply again, could i run the meter just from battery to the main positive cable or does it have to go to each wire.
