Loss of power

Hi all, i just found this site today and it is a great idea.
Cheers to the guy who started it.!!

I have an 89EA 3sp EFI, On occasion when I turn corners usually left, the electrics on my car cut out. I am guessing that it is prolly a loose cable or connection somewhere but I am not sure where to start looking. If anyone has any ideas where to start that would be helpful.

Also I am having problems with the car loosing power for no reason. It usually happens when I am accelerating. Could this be my Injectors??
If I put in some injector cleaner would this help??

Any advise would be great.

Has your car been lowered? A similar thing happened to my mates EA were all the electrics were going wacky. What happened was when he once reversed out of his driveway he scraped the back and broke of the connection for the trailer lights, which created a short. I guess you could start by looking there!

Re: Loss of Power

Sorry I didn't give full details.
No fuses blow but the stereo cuts out for a few seconds, Head Lights and dash lights flicker, the car shudders and when I am going slow enough the car would stall.

Any help would be great.

Just a few quick checks.
Firstly, check your batter terminal connections for corrosion.
Then check to see if the alternator wires are all done up nicely. Then check the earth lead that goes from the battery to the engine.
Finally, there is an earth lead under the car, near the trannie/gear box. This is probably not making good contact and usually makes a load of problems.

Re: Loss of Power

well, id begin by checking all the main cables to your battery for any shorts or other dodgy electrical things. it could be a bad ground, so maybe check your chassis and engine grounds first. for everything to be going at once, it should be major, and easy to find :)

G'day Chris,
Mine started doing that one day when i started it the lights would go haywire and the ingine would cut out if you put your foot on the brake pedal, etc etc. I knew it had to be an electrical problem cause when the car ran it ran beautifully. I made an earthiwe and put it from the battery (negative) to the chassis, and gthis fixed it. Then I had a good look under the car and as Bass said it was that one from the trannie to the chasiis.....

re: Loss of Power

Thanks for all the info.

I am not a great electrician so you will have to treat me like an idiot,
I found one cable that wasn't connected to anything it was about halfway between the firewall and the battery.
It is White with a blue stripe, and has a ring on the end of it.
Could this be the Earth cable??

Where is the best place to connect an Earth cable.

Tim, how do you create an Earth cable.

Re: re: Loss of Power

Earthing is simply connecting the negative terminal of the battery to the body off the car, so power is achieved by creating a circuit through the body of the car, and a positive wire. An earth can be made by running a LARGE (thick) wire from the negative terminal of the battery to bare metal on the body of the car. Don't use small (thin) wire, because it may overheat from too much power going through it. Take a look at the negative wire running to your engine, and use the same size wire... Either buy some (Pretty expensive), or cut up a pair of jumper leads, and use the black wire from them :)
