Electrical system turns off when I try to start the car.
When I turn the key to start the car, instead of tunring the engine over, the entire dash goes dark and everything turns off. The factory alarm tries to go off when I turn the ignition back off. When this first happened, moving the positive terminal fixed it. But now even a thourough cleaning of the terminal and clamp gets me the same result, no start.
Re: Electrical system turns off when I try to start the...
I had a similar chronic problem with my 'stang. I eventually replaced the whole battery cable for both the positive and negative and never had any more problems with the electrical system. The factory terminals can get so corroded that they are no longer sufficient to support the high current of starting the car, and simply cutting the terminals off of the cables and attaching new generic ones from the autoparts store doesn't do the trick either.
It isn't too difficult to do this yourself once you can find the right length and type of cables. They run from the battery to the starter under the engine on the passenger side, along with the little wires that connect to the chassis for the negative and the accessories power for the positive.

1. So the car was running normally and then on one occasion you put in the key to start it and all the warning lights flash up on the dash and the starter motor will not turn the engine over. Is that correct.
2. When you last drove the car were any warning lights appearing on the dash.such as check engine warning, engine overheating, electrical charging warnings etc.\
3. Has any work been carried out on the car recently.
Same thing is happening right now on a 2002 Monte Carlo. When the key is simply turned to ON, all of the lights on the dash starts blinking rapidly. When I attempt to turn the car over, there is no CLICK or anything from the engine - nada. Ignition turns and the dash goes dark, as if it wants to TRY to start - but nothing happens. But, when I press the brake pedal (and the key is just sitting in the ON position), all of the blinking lights stops flashing and just stay lit. Therefore, I changed the brake switch, thinking it might make a huge difference. Didn't really help at all. When the key is turned, you can hear the fuel pump engage and everything seems to be ready to go. But, the car won't start (it will only start when it feels like it)...hit and miss, pretty much. Does anyone know the TRUE solution to this issue? Does the ignition need to be replaced in order to get this car to crank over
this sounds like a low battery problem ... the horn and lights do not take much energy to turn on, but starting the engine takes a lot of power. Try jumping the Jeep with another car, or a battery jump pack (available at any auto-parts store). If the engine kicks over and starts, then leave your Jeep running in park for about 15 minutes. After 15 minutes of running, turn the Jeep off and then try to start it again with no jump -- if it starts, you had a low battery, but the issue is probably solved (running the engine recharges the battery). If, after you have had the car running for 15 minutes and turn it off, it does not start on its own, you probably need a new battery (and you should have your electrical system checked as you might have a bad alternator that is not charging your battery). Sears Auto Canter has a great piece of equipment that can test your battery, and your entire electrical system (including the alternator) in just a few minutes. I recommend that you take your Jeep to a Sears Auto Center and have it checked, whether or not the jump worked because their system can make sure that there is not a slow drain on the battery (due to a loose connection or something like that) which would cause you to have the same problem again.
First , check the LED on your car battery, if it is blank you made need to remove and test the actual battery. If there is ANY chance that sparks flew when attempting to boost the car open the fuse box and check the fuses including the large ones. Third, try a different key, including your flat wallet key in case your key has also failed due to a weak internal battery and will not communicate with the engine immobilizer. To use your 'wallet key" hold the black card against the dash beside the key slot while turning the key in its slot. This key has an embedded security chip in it as well to allow the engine to start. If your RX is a 2010, hold the wallet key or your black key fob to the dash beside the ignition button and wait for the LED on dash to turn green. Then push the button.
