Doubt the alarm system has anything to do with dead battery..I would check condition of the battery and have load test done on same.If the battery checks out ok then go to charging system.Using a simple volt guage check battery with engine not running..Now crank up that puppy and test the volts at battery. should be higher than with engine not running.Not running should be 12 to 12.5 ;running as high as14.5 .I think thebattery is suspect ..

My aerial works on my old tv set, but when connected to my new philips flatv, it says i should check my aerial connections.

Hi Gabrial,
The old day TVs used to work even on weak signal. Modern day flat panel TVs need real good and strong signal to perform well. Please see that your TV antenna is in real good condition and properly oriented.

Fuse 8 on 1990 allante is drawing down the battery. will completly drain battery in 2 days

Have you checked BCM input parameter BI61? That is the most common cause of the 2-3 day battery drain. Have you tried pulling fuse #8 under the ash tray for the CPS to see if that stops the drain? You can pull one of the plugs off the AC blower control module to isolate that. If you can not hear the blower motor running with the key off, that probably is not an issue.

Battery dains when not running

The battery current draw may be caused by a few things, here are some to check: the most common is that a light stays on like the dome light, the brake l;ights may be staying on,aftermarket accessories can cause it as well, audio amplifiers or stereo equipment or aftermarket alarm systems, very common.

Alarm keeps going off took battery cables off 2 try and let computer reset still goes off


Alarm Modules are one of the Common problem in these Models.You could try:
Find the Red / Black wire at the Hood Switch, located above the Fan & connect one end of a piece of wire to the Red / Black wire.
Connect the other end of the piece of wire to Ground (chassis)
This should Dis Arm the Alarm until the wire is removed.

This will only work "if" the Alarm Module is Not Defective.

Let me know, if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

92 Dakota Club Cab v8 battery keeps dying?

Turn everything off,remove the key, then with a test light check the fuses. You will need to check the interer light is off. This should lead you to the trouble. Also if it has a alarm, this will **** away power too! Frankster016

Whats wrong

Causes of excessive current drain in late model vehicles include things like lights that remain on (trunk and hood lights, interior lights, brake lights, etc.) and also relays that may be stuck on, or modules that are not going to sleep or powering down.
A fuel pump relay that sticks on may keep the fuel pump running after the engine is shut off. A switch or relay that powers a rear window defogger can stick on, pulling current from the battery after the ignition is off. An electronic suspension module, abs module or keyless entry module may remain active long after it should have powered down.
An accessory such as a DVD player, game console or cell phone charger left plugged into a rear seat power receptacle may be pulling power from the battery. So before you spend a lot of time trying to figure out where the amps are disappearing, check all of the vehicle's power receptacles to see if something is plugged in that may be using power. The battery can be checked with a voltmeter using the aMp selection. 50 amps is to high. A mechanic can help you with this procedure.
