Battery drain points to instrument cluster

Battery was going flat over night so i did an amp test and discovered a drain of 0.73 with everything shutdown and all doors locked, then i pulled fuses and discovered that fuse 13 which protects ignition lock and instrument cluster, so i disconnected ignition lock which is electronic and the drain was still there, which leaves the cluster as the problem, when the whole system is shut down the cluster seems to go to sleep , but according to the amp test it still drawing too much , because it has to keep clock and other information at hand so to speak, i think 50 milli amps would be stable enough of a drain , but the extra 23 m-amps is draining the battery overnight, So my question is , would the can-bus be responsible

SOURCE: My Lexus ES330 2004 battery is being drained. I

how long did you let it sit before you checked the ecu as some computers can take up to 5-10minutes to power down.another thing did you make sure everything was turned of and unplugged and all doors closed,have seen some people think everything was off only to find out they forgot something.have you checked the wreckers for a used one,if you write down the ecu number that is on it they may be able to match it up with one they have for less money.

Do you have info about 2003 grand caravan electrical issues?


You're going to have to find the rest of the rat damage and fix whatever you broke when you replaced the power box. Your diagrams are available at the link below. Save them to your pc. You can also review bulletins there, but probably nothing about where rats like to chew. When you get it down to something manageable, we can probably provide some help.

03 silverado cluster went dead when battery went dead ,put new battery in and sill nothing ,can you help me


Do you own a professional type scan tool ? Would need to see if the instrument cluster can communicate with scan tool . That would be a priority . If the instrument cluster ,for some reason wouldn't be talking,checking power an ground for the cluster . Batteries going dead , changing batteries without a alternative power supply can cause modules to go to sleep permanently ! Battery Disconnect or Replacement Problems I'am not saying that's what happen to your's . 2003 to 2006 GM had cluster problems ! The solder use in the cluster caused silver migration , instrument cluster caused a drain on the battery overnight . Watch these videos !

Battery drains until dead recharged it tahoe starts and runs gauges are dead alt light is on door locks, windows, keyless entry don't work 2003 tahoe 5.3 please help


Try disconnecting your alternator. Charge the battery but leave the alternator disconnected (remove the electrical plug from the rear of the alternator).

If the battery retains its charge and can start the car (you won't cause any damage by starting the engine with the alternator disconnected) it points towards a defective alternator.

If the rectifier pack - the diodes - in the alternator burn out this can cause a battery to discharge very quickly. Sometimes, quite literally, in a couple of minutes.

If the battery still discharges with the alternator disconnected this points towards a failing battery or a drain somewhere else in the electrical system.

It may be that your door locks and windows don't work for the simple reason there's not enough power to operate them. However, as you say your gauges are dead .. this could possibly point towards a drain in the electrical system, but not necessarily so.

It becomes too easy to replace parts one after the other in the hope that a fault is cured. This is an expensive way of going about things. The best option is to pay a workshop or an auto electrician to diagnose the fault correctly. Diagnose the fault first - an auto electrician will be able to tell you within minutes if it's the battery, the alternator or a drain elsewhere.

Vech keeps looseing charge over night? batt,alt and starter all test good. so wht cld it be? it is a 2005 dodge durango


If you have replaced or had the battery checked out and if you have had the charging system checked out and still the battery is drained overnight, I probably have the answer. I had this same problem for a couple years and AAA was ready to cancel me. Mine turned out to be a bad instrument cluster. This item is on recall by Dodge and if it is the instrument cluster, repair and replacement is covered on the recall. You can go the Dodge/Chrysler website and check you vin against the recall list. They had to replace mine twice before the problem was resolved. Your local dealership should be able to help you with this. I had to take it to a well known facility which specialized in auto electrical problems. They traced it to the instrument cluster right away and I used their report when I took it to the dealership for the second time. BUT IT IS A RECALL ITEM AND REPLACEMENT, IF BAD IS COVERED!!! (just a little good news if this is the problem).

Instrument panel went dead


Checked Every fuse in the fuse box (no small task).This includes #4 - Power point Instrument Panel, #14 - Day time running lamps (auto lamps doesn't work nor does auto lock), #27 - ignition switch run feed, #35 - Instrument Cluster, #41 - Instrument Cluster, #42 - Delayed Accessory, #45 - Ignition switch run/start feed, #102 - Door locks body security module, #103 - Ignition switch, #110 - Ignition switch, & #116 - Ignition switch. But I also check all other ones as well, they all register OK. AC panel & radio work. Turn signals work. Mileage does not work, trip computer does. So, basically, everything works except auto head-lights, auto locks, and the dash cluster (no MPH, RPM, mileage display, Fuel, Temp, Tran Temp, and Oil Pressure).
