That's the wrong way to check fuses with a test light! What you SHOULD do is, have both battery terminals connected to a good battery, and connect your test light ground lead to a chassis ground (assuming you have a negative ground system), then CAREFULLY touch the test light probe to one side, then the other side of each fuse. Any that DON'T light the test light on BOTH sides are bad fuses!

It sounds like a short you can test by removing the NEG. cable from the BAT. put a volt meter from the POS. red lead on post of BAT. and black lead to engine block or known good ground if you read voltage you have a short .
Your tow and hall switch sounds like the place to start look at the fuse box although a blown fuse would cut power off to it but look anyway.
Next check all of your lights brakes blinkers running reverse tow and hall means you have a plug to hook up to trailer lights some ware . It could also be a brake switch at the brake pedal. You need to think its likely some thing vary simple a bad connection at a bulb or lose ground wire but its in the lighting system .This could have shorted the tow switch out see if you can reach up under the dash and unplug the tow switch but check all these other things first think about the problem before you do things you can't prove

Battery is constantly going dead. replaced battey and alternator and still having problems

Hi, What you describing to me sounds like you have a short some were. There is a little test you can do to see if this is your problem. Roll down window take key out make sure all accessories are off raise hood disconnect pos side of battery , if there is a hood light unplug it. With battery disconnected on pos side let set for 30 Min's to let all modules go to sleep. Then take a test light and hook on pos battery post ,then put other end of test light to pos cable see if test light come on if so you have a draw some were start at out side fuse box pull one at a time to see which one cuts test light off. when find the one that cuts it off see what all runs off that circuit. Then put fuse back and unplug each item on that circuit tell light goes out . that should be your problem.

also have you had any thing installed lately like radio, CB, amp
This will give you a good start with your problem. If i can help feel free to re post
Thanks dodge tec

you would want to make sure everything is turned off in the truck and doors are shut. Take the positive battery cable off, connect a test light to the positive cable and the other to the battery, if there is a drain, the test light will light. Try pulling 1 fuse at a time til the test light goes out. Also have the battery tested to make sure it holds a charge.

Battery will dran over a short time and is the second new battery

The best way I have found to hunt down a current draw is with a multi meter set to the DCA setting (this will detect DC current flow). With the vehicle shut off, systematically remove fuses one at a time and place the leads from the meter in the connectors that held the fuse (one lead per fuse connection). You should have a little current flowing to the radio, for the clock, and maybe some to the engine computer and, if equipped, the alarm, the rest of the circuits should have no draw. This will narrow down your search to one circuit in the car, which can than be further diagnosed, usually it's a wire with the insulation rubbed through.
P.S. if the car has any after market equipment, such as audio amplifiers, start your search there. Hope this helps, good luck!!!!

How do I find a electircal short. After sitting

You have a draw, not a short. Disconnect the positive battery cable, and put a 12v test light between the cable and pos. batt. post. Light will illuminate indicating power is being requested by a circuit. Start removing fuses one at a time until the light goes out. That will be the draw circuit. Check the items on that circuit for the one that isn't shutting off.

1990 Toyota Camry has electical short

with the aid of a test light disconnect the negative terminal to the battery and connect one end of the test light to the battery and the other end to the terminal cable if its lit there is a draw begin by pulling 1 fuse at a time until the light goes out and that's the draw most likely a glove-box switch not making full contact or a trunk switch even the dome light adjust the switch as necessary either try a shim or possibly bend the fixture forwards or remove the bulb all together if you desire

My 91 honda accord goes through new batteries like they were a bag of potato chips

Try this. If you have a test light (very inexpensive at auto stores) disconnect the positive battery cable. Then connect the test light in series (pos. end of test light to battery pos. and the alligater clip to the battery cable). Turn off everything possible in your car. If the test light stays illuminated, you have a constant draw. If this is the case, you'll need to track it down.
Here's how: Re-connect the battery and keep everything you can off. Take your test light and connect the clip to a GOOD ground near the fuse box. ( right side under dash) Remove each fuse and test the contacts from the power side. The only one that should light it, is the clock and security system. If any thing else lights the light, there is a short in that system. If this is the case, you'll need to physically follow the circuit to the battery. Disconnect each connection and test the connector on the battery side untill you get to the connection that does not light the test light. The faulty switch or relay or short will be in between those two connection. Replace the component and your done. Have fun. I really enjoy these kinds of challenges.

P.S. I have the service manual for this car on a PDF file. If you need it, contact me and I'll give it to you. (free)
