Electrical problem need help
It has been about 2 weeks since i have started my 91 tt and when i tried to crank it today it was completely dead, the lights wouldnt even turn on. The car has a 1 month old optima red top and brand new marine terminals (top post). I am fairly mechanically knowledgeable but i am lost when it comes to the electrical system. Is it normal for the battery to be dead after such a short time or is there a possible electrical drain? Thanks in advance for the help.

Re: Electrical problem need help
Charge the battery, get a meter, set it to amps, then disconnect the negative battery terminal. Put one probe on the battery terminal, and one on your negative cable. Anything more than .5 amps and you'll kill the battery after that amount of time. Leave the meter hooked up and start pulling fuses one by one, checking each time until your amp draw comes down to an acceptable level. Look at which fuse you pulled, and start checking the components on that circuit. I'd get a wiring diagram too, because sometimes they put more things on a circuit than just what is listed on the fuse panel.
This is all with the key off... The half amp or so will be the memory for the computer and your radio... If it checks out, you maybe left the hatch open or the dome light on or something. Oh yeah, security system too... so as long as its below 1 amp, you're probably fine. Two weeks IS a long time, as you do have all those things running with the key off... If you leave it sit for that long, you should probably get one of those batttery tenders. I had a Jaguar that would kill the battery if you let it sit for a week. If you drove it every day, you never had a problem... |

Re: Electrical problem need help
Are the marine terminals painted? The reason I ask is because i had the same problem 2 weeks ago. I jumped the battery and took my car to advanced to check the alternator and battery and found that the paint was not allowing for good contact and therefore causing a drain. I sanded the areas where the cables meet the terminals and hooked everything back up. no problems since.
oh and i got a new battery as well and even after switching it out the car still woouldnt turn on until i got the paint off the terminals.
