hey guys please help me. i have a rx7 gxl s4. and it doesnt have any power. i turn the keys and no power whatsover., but my lights seem to work... im not sure if the battery is messes up, or maybe i busted a fuse because i was messing with my power windows, then tryed starting it, but didnt work... im frustrated

 

check voltage across battery posts. check fuses.

Don't panic.

 

Hey, don't worry. Same thing has happened to a number of people including me. Check all of the fuses and start looking for grounds. My problem was one ground not connected to the main fuse.

 

Seems like a blown fuse or fuses. Pull em, look at them. Both under the hood and under the driver's side dash. I'm gonna make a wild guess and say it's the BTN fuse. Lemme know if I'm right.

 

oh okay thanks guys...ill ddefintely check those fuses

 

check the fuses. Does the starter crank at all? Maybe check the main relay see if it clicks. Its located by the brake booster.

 

nope, and i have no power whatsoever., but the headlights work

 

Make sure your grounds are intact; I had that problem in my dad's Corvair once, and that stopped it from starting. It's a much simpler car, but this does sound like a very simple problem.

Oh, and like the other guys said, check your fuses

 

yeah i just checked em, and the following fuses dont have any power.
power windows
turn
meter
engine
pwr steering
cooling fan
wiper
rear wiper
sun roof
audio
cigar


all of the fuses are okay
but they dont have pwer

what is it?

 

check you main fuses. the ones in you engine bay?

 

oh yeah those are okay, and they do have power. i just dont have power in the fuse box beneath dash.

 

Sounds like the main fuse(80 or 100amp fuse depending on s4 or s5) mine did the same thing headlights worked but nothing else even if it looks ok take it out and check it.

 

yeha , i got it started yesterday...but i didnt do anything. it just worked by itself. i messed with the main fuse even though it had pwer then it worked. what is this madness?

 

This is actually a common problem that has nothing to do with fuses. There is a single spade connector from the main fuse box to the wire loom that is right next to the battery box. This connects the power from the 80/100 amp fuse ultimately to the ignition switch. Apparently, battery fumes corrode the connectory cutting off electricity no different that what happens with dirty battery posts. I've personally only seen this issue with Verts, but no reason it doesn't happen to any 2nd Gen.

When you messed with the main fuse, you probably jiggled the connector causing it to temporarily connect again. Trust me, it will go dead on you again soon.

Pull apart the connector and scrub it completely with a toothbrush and vinegar/water solution to melt away the corrosion. YOu might want to heat flux and solder to where the connector meets the wire itself. Then coat the connector with dialectic grease and you should be ok.

A quick fix otherwise would be to run a jumper wire from the main fuse (be sure and attach to the battery side of the fuse) through the firewall to the main power connector under the dash. But ultimately you need to fix the problem at the connector location.

 

The connector HOZZ mentioned is about 6-10" past the fuse box towards the firewall.

 

Nope, the connector I'm talking about (at least on a Vert) is about 3-4" below the main fuse box next to the battery box before the main wire loom. If it were 10" from the main fuse box toward the firewall, it wouldn't be affected by acid fumes from the battery.

Would be surprised if different on a NA coup, but might indeed be different on a TII.

 

thanks loads guys!! turns out that this is happening alot now. but after wiggling that connectr its works!.
