    Ok I tried that and still get a spark. I removed the other terminal , still got a spark. I did have some problems last winter with the doom lights, that was the push switch on one of the doors I lubricated it and problem solved..Tthe lights are not on when all doors are shut, they all work. Is it possible to have a short in the switch and not have the lights come on...thanks

    Hi....you sent a reply that it may be the alternator....it wasn't so is it possible that it is one of the door switches for the interior lights. i has a problem with one of the doors but after lubricating the switch the problem went away Is it possible to have a short in the switch but still have lights working...thanks

  • jcbatch May 17, 2011

    The door pilar switches all work, lights on and off as they should do. Would a mechanic be able to put this on a diagnostic machine and have the machine detect the problem . I am in agreement with you, if we had a short fuses should blow...thanks

The most likely cause is the alternator so disconnect the big cable to the alternator and see if you still get this discharge ,this is the most likely cause of battery discharge ,although the alternator will charge the problem lies with the diode rectifier pack inside the alternator whereby a diode goes down and allows the current to run back to earth hence discharging the battery ,yes i know a boot light and silly things like this will also do it but from experiance 99% of the time its the alternator .

    dome lights or interior lights ,yes their could be a short here but iam not familar with this model vehicle as iam in spain ,yes we do have jeeps and explorers but few and far between ,also another problomatic cause i often get is add on aftermarket car alarms ,and i have also had on a jeep occasion where the amplifier under the back seat wasnt turning off ,but the switch in the door for the interior light can short out against the body but normally i would expect this to blow a fuse ,Another problem i had once was with a computer fault ,the ECU uses a big transistor to connect the earth so all teh spark and fuel pump ect work for the vehicle to run and this transistor had melted internally causing everything to stay on and this in turn run the battery down this transistor is the in effect the immobilisor switch.try the door pilar switches first though as the next step

    no i dont think a scan would read this problem ,i would be inclined to pull all fuses ,take a picture so you know where they go and try for the short with no fuses and see what happens as the spark could be about 5 amp discharge and this may not be enough to blow a fuse .iam going in shower now as its 22.30 in this time zone and i started work at 0800 this morning and iam getting a bit of a stiff back to say the least ,another early start in teh morning i have to go into alicante to the local traffic office to present papers to import a car ,an american ford mustang ,what a job changing the back lights to conform to europeon specs and also to get the mechanical inspection as these american cars do not have a chassis number stamped into them only a plate in the windscreen and for the import duty ?? well they worked a value on spanish car prices which are substancialy higher than UK prices where it was imported through from america,they took the price paid in the UK add a lot more for spanish values then 14.25% at the higher CO2 rate and come up with a figure of 2149euros plus on top of this was the engineers certificate and the inspection ,Still have the registration fee to pay as well ,still i do earn on these paperwork nightmare jobs owing to the british reluctance to learn spanish when they come to live here .So iam not complaining too much .

Anyone have battery and inside electrical issues? the dome light comes on when you open the pass. side door but not the driver side. I am also having issues with the battery going dead constantly.


First find out why battery is going dead. With hot battery, disconnect negative to battery and see if it sparks when you touch the neg back to the neg post on battery when everything is turned off and doors are closed. If yes, remove fuses one at a time and retest until you find one that makes the spark go away. See what that fuse controls and fix short (can also be a stuck relay). To find bad relay connect battery and let sit for a few minutes, then feel the top of each relay to see if one is hot.

Battery system surge? postive and negetive touched. now i have so many problems . help


Oh dear... shorting out the main battery terminals can cause spectacular electrical problems. If the main 15 amp fuse keeps blowing , it would suggest a dead short. Make sure that any of the smaller cables that are usually fixed to the battery are on the correct posts. The negative battery lead will go directly to the body of the car and or the engine case. The large thick positive, will go to the starter. The smaller wiring usually goes to the fuse box and then to the ignition. You may need an Auto Electrician to suss this one out.

Try this tips:
1. Check the battery voltage at the battery with the digital volt/ohm meter. Set the meter to "Volts D/C" and touch the black meter lead to the negative battery post and the red meter lead to the positive post. A fully charged battery will measure 12.7 volts or more. A measurement of 12.5 volts is considered discharged, and the battery should be charged before any further testing. Any measurement below 11 volts indicates a severely discharged battery--the battery is most likely damaged and should be replaced. If the battery measures above 12.7 volts, proceed to the next step.

2. Check the starter for battery voltage by touching the red (positive) meter lead to the battery cable terminal on the back of the starter and the black (negative) lead to the chassis. The voltage reading should be approximately the same as the measurement at the battery. If the reading is lower than battery voltage, check for bad connections at the cables on the battery and the starter or ground cable.

Check for ignition switch signal at the purple wire on the back of the starter. When the key is turned to the "Start" position this wire should measure battery voltage. If the reading is less than battery voltage, or zero volts, check the fusible links (orange wires) on the back of the starter. If the fusible links are intact and not burned or broken, replace the ignition switch. If battery voltage is present at the purple wire, and the starter doesn't turn, replace the starter. If the voltage measurements at the starter are correct, and the starter cranks the engine over when the key is turned to the start position, proceed to the next step.

3. Remove the air duct attached to the throttle body, and spray a liberal amount of the carburetor spray into the throttle body. Replace the hose, and try to start the engine. If the engine starts, the fuel pump is not supplying fuel or the ignition module is not pulsing the injectors. Check the fuel pump fuse located in the under-hood fuse block. If it is good, check for power at the fuel pump electrical connector located near the rear of the fuel tank on the driver's side of the van. In the Chevy Astro van, power is supplied to the fuel pump by the the gray wire on the electrical connector when the engine is being cranked. If power is supplied, hitting the fuel tank with the flat side of a hammer while someone else is turning the ignition key to start will sometimes bump the fuel pump enough to allow it to start. If the fuel pump checks good, proceed to the next step.

4. Check for spark. Disconnect the coil wire at the ignition coil, and try to start the engine. If no spark occurs, replace the coil and ignition module. If a strong spark occurs, plug the wire back in, and remove a spark plug wire from a spark plug and repeat the test. If a spark is not present, replace the spark plug wires, and distributor cap and rotor.

With battery ground disconnected and positive connected if i take a voltage tester and touch from battery ground to chassis ground i get 12.52 volts, just what the battery tests,+ to -.


Are you sure you were touching the negative post and not the positive post. If you checked the positive post and the other wire to body chassis then you should get the reading you say here. Negative to negative is negative and you should have had no reading at all. Please do this test again being absolutly posative your touching the negative post. There will be a - sign on the battery under that post. Get back to me after the double check, Raz

Battery keeps going dead. 06 ls430


With the engin not running and the key off, lift the hood and disconnect the positive lead on the battery. Then touch the lead back to positive terminal on the battery. If a spark is seen, there is something still on in the car. Could be the power mirror switch, seat heaters or even a car phone. Trial and error to find it.

Sorry I can't be more specific but that is the test.

Good luck.

Drainig battery


You have either a battery with a dead cell that must be replaced, or something is on and draining the battery. Check the under hood, trunk, glove box, brake, parking, and courtesy lights. Open the hood at night and remove the negative cable. When you touch it to the negative battery post if you see a fairly large spark, something is on or something is drawing power. If you see a very tiny spark that is normal as it is the radio & clock pulling power. Replace the battery.

1996 golf gti wont fire up


what about checking the ignition or the fuel pump relay? i wouldnt try touching the positive and negative leads together even after five minutes as the ciruit has capacitors and inductors in them and this could cause damage to the electronics.if there's no fuel and no spark it sounds like a common fault. try disconnecting your immobiliser behind the glove box (most of the mk3's starts with them disconnected)

Car battery keeps going down


You seem to have an electrical drain on your battery from what you are saying. However the drain can be coming form you alternator. With some skills I can tell you how to check for the source of this drain, Its an old technique that I learned years ago. Get a regular test light(the one with a bulb/light in it) disconnect your negative batter lead from the negative post on the battery. Connect clip end of test light to battery pole. Touch pointed tip to battery cable(negative one) With ignition key off and out of ignition and all doors locked and ALL OTHER ACCESSORIES OFF... this test light bulb should NOT be lit. If it is there is a drain. Go to main fuse boxes and remove fuses on at a time(MAKE SURE ALL DOOR ARE LOCKED AND ALL ACCESSORIES ARE OFF when doing this procedure) As you remove a fuse if light is still on replace in the same spot and move on to next fuse until light on test light goes OUT. when it does "Bingo" that's the circuit that has a drain in it. Some accessory in that circuit is draining your battery. Locating the source should be easy the fuses are marked by what they control. Contact if you need more help. Good Luck

My starter


the wires might be fried also, check them with a meter to see if the smaller wire has voltage without key in. if so, the wire might be shorting out to 12 volt wire or the ignition switch is bad.
