Question about Cars & Trucks

Open Question

What, besides battery failure, causes Simplex 4009-9012, to send a battery trouble to the 4010 panel?

Batteries are 24.9 volts. 4009 alarm shows no trouble by LED's unless batteries, AC, or NAC circuits are disconnected, but 4010 panel states 4009 battery trouble. Trouble alarms have been about same time each evening. Can only be reset by disconnecting AC and battery leads. Are there any specific voltage values to check. AC and charging circuits are fine, but battery charge circuit shows no voltage unless batteries are in circuit at 24.9 V.

SOURCE: lexus alarm keeps going off unless you disconnect battery model g300 1996

I would say you have two options, You can take it to the dealer and have it disconnected, or you can go to an aftermarket car stereo/alarm store they will install an aftermarket alarm and disable your stock one at the same time, for probably about as much as the dealer would charge to just disable it. First just call the dealer to get a quote on how much that would cost, and then call the alarm place and get a quote.

Try removing the alarm system relay, some car alarm has also a fuse on the alarm that you can remove.
Many car alarms unlock by inserting and turning car key while you connect the battery.

I am having trouble also but I need to know how to disconnect the alarm. I would appreciate it if you could help me out seeing that you have disconnected yours. Thank you

If the alarm keeps going off constantly and the remote has no influence on the alarm its most likely a connection problem. A hyundai dealer might be able to fix it but since you can start the car something you might be able to try is....
Check and make sure the remote battery is in the right way. Make sure all of the doors are closed, the trunk is closed, open the hood, connect the battery, close the hood all the way and try to lock and unlock the doors. Hope this works but if not, sorry it didn't work.

SOURCE: Fuse box diagram for 1998 Ford Escort

follow the wires from the alarm itself and trace it of that is not the problem then use a test light between the battery terminal by disconnecting the negative terminal and connecting a test light to the cable and the other end to the battery itself if its out no draw but if lit there's a draw pull fuses one by one with the door switch pressed in to nit get a false reading and when you find the test light goes out that's the problem use the chart guide to find out what # it is and that's yer problem solved

48 volt club car 4 12 v batteries one batterie checks 20 v when I single it out when I unhook it it checks 12 v

If you have 4 off 12 volt batteries connected in series (positive to negative leaving a positive terminal and negative terminal with no wires on then that is 48 volts. To check the batteries you have to disconnect each battery and have a load test done on each battery for 12 volts and dead cells. To get 20 volts you still have 2 batteries connected together with a good battery connected to a battery with a dead cell or else you would have 24 volts.

late answer i know.

but no, the simplex 2001 is not an addressable fire alarm panel. it is a zoned panel.

this panel has not been made for several years and new parts cannot be obtained. it may be possible to obtain used parts if you call your local simplexgrinnell office.

Trouble with the alarm system. Had to unlock the passenger door,if not the alarm would activate and run the battery down. Now when the care is started the alarm system was activated, causing the battery to...

The weak battery can cause this. Remove battery, trickle charge overnight, and have tested by a reputable garage, out of vehicle. My bet is that you have a very weak battery, and Chrysler products will have all sorts of alarm problems if the battery can't hold 12 volts overnight.

Would 16 volts burn out the glow plug relay on my 2001 power stroke I have replaced the relay twice in the last week and cant find any other reason for this way premature failure Please Help

Yes, the extra Voltage can overload the Relay. You have several problems here. The Batteries are suppose to be connected in such a way to give you 12 Volts. If you are measuring Voltage to the Relay without the engine running, the main battery cables must be wrong. But one of your batteries must be shorted because two X 12 Volts is 24 Volts, not 16. Unless your dash Voltmeter is pegging out at 16 Volts; you are really getting 24. Use a Multimeter set to Volts and retest to see what the actual Voltage is.

If you are measuring Voltage after the engine is running, the Regulator is bad and allowing too much Voltage in the system which can burn out about anything designed for 12 Volts. It would not be much of a factor for the Glowplug Relay though, because it should shut off before you crank your truck. So in theory you would not be generating 16 Volts while the Relay was working.

You can get a free load test on the Batteries and the Starter at Autozone, Oreillys, and Advance autoparts. Ask for a charging system test. Some Walmart stores will test, but I do not know if it is free.

I hope my solution is very helpful in providing you some items to check to cure your problem.

I have 4 12volt batteries and need to wire them to give me 24 volts

This won't actually give you 24 volts... All this will do is give you more amps in a traditional circuit. You could run them in a series.... but I wouldn't recommend that. Those batteries are built to provide 12 volts. What do you need 24 volts for?

24 volt charging problems .2 12 volt batteries 1 battery 16volts and the other about 9-10 volts

A 12 volt battery is actually 13.2 volts fully charged. If you are reading 16 volts, you are probably getting extranious voltage from the system somewhere, especially if the vehicle is running when you check the voltage. The alternator will put out about 15-18 volts to charge the battery normally, and yours may put out 28-32 volts to charge them in series, but the batteries, when disconnected, should never read more than about 13.2 volts each. Typically, it will read about 12 1/2 volts when disconnected. COMPLETELY DISCONNECT BOTH OF THE BATTERIES. If you still read 16 volts when it is disconnected, you must have a bad meter because the battery can't produce that much voltage, no matter what. (Six 2.2 volt cells connected in series inside the case.) Put the meter on a known good battery on another car that is not running and see if you get the same reading. It sounds like the other battery is almost dead, regardless, and it sounds like your series/parallel switch may be malfunctioning. (That is the switch that puts the battery in series to run the 24 volt starter, then puts the batteries in parallel to run the remainder of the vehicle on 12 volts. This is all assuming that you have a diesel vehicle with a 24 volt starter and that is why you have two batteries.
