Question about Lexus GS 300

1 Answer

I hooked up an amp meter on positive side of battery, everything off, it showed 300ma of battery drain. After pulling all fuses; I found one fuse that zeroed out the amp meter. The fuse is located in the passenger side relay box. It is a 10a fuse, titled (ECU-B2). I am stuck now, what is ECU-B2 mean & where do I locate it? Can anyone please help. Thanks, JD

Try a local repair shop with a data base
Have them show you the wiring diagram
The circuit the fuse is on won't get you to
the module, not timing out
You should be around 40ma or less when they
go to sleep

I seem to have a bad ground wire that drains the battery sometimes,how do i locate the ground wire.This only happens when I first start it and drive,it sits and recharges itself back up.

Looks like you have a "parasitic current draw" not likely the bad ground. Use an Amp meter, set it on 10 amp setting, shut off everything inside the car, make sure nothing is plugged in in any power outlets. Shut all the doors. Remove the battery positive terminal and hook up the amp meter between the positive battery terminal and battery positive cable. see what is the meter reading. The normal draw is 0.05 amp and less. If the draw is more then that you have a draw. The way to pinpoint the faulty part that draws the current is to, start removing the fuses one at a time and monitor the amp meter to see when the current drops to normal. As soon as that happens look at the fuse and see what part is that particular fuse feeds. most likely you find the culprit.

My 2002 Chevrolet Blazer cranks like a champ the first time every time as long as I crank it every single day. But, if it sits two or more days and I do not crank it at all it is very hard to get it...

You have a short somewhere in electrical system of truck that is slowly draining battery. When battery is too low, cranking speed and voltage is too low to operate electrical system to allow fuel etc to start truck. First make sure dome light is not staying on after you close door. Sometimes a kneecap hits the dash switch that turns on domelight. Second make sure battery is FULLY charged. Have auto store check battery to see if it is fully charging. At same time they will check to see if alternator is not malfunctioning and charging correct amount. Replace as needed. If all checks out OK...Third, get an amp meter, remove negative battery cable. Attach one probe to the negative cable and other to negative post on Battery. Turn amp meter on. It should read zero. If reads anything it is showing you have short in system. With meter hooked up this way(I use radiator clamps to secure probes to post and cable) Start pulling fuses first, one at a time, then relays in fuse box to until meter goes to zero. When goes to zero you have found the circuit. Look at fuse box picture in owners manual that came with truck. Replace relay or relay connected to the circuit shown in manual. For instance if fuse you pulled to make it go to zero...says it is for wipers and windows...look at manual diagram and locate and replace relay for wiper or windows one at a time, then check amp meter to see if battery drain continues...If you can't locate source of problem you have at least identified circuit. You can get all data schematics at library from ALLDATA free....then try to track down further...if not able to do yourself take to GOOD auto shop that does electrical work. at hardware, auto parts store or Wal Mart....Red wire at least 6ft long. one Toggle switch, get inline fuse connector and a matching fuse that matches the fuse you pulled out that makes amp meter go to zero( If 5 amp, get tubular 5 amp fuse for inline connector) electrical wire connectors kit. Make two 3 ft long wires. Put connector onto both wires and screw tight onto toggle switch. Now cut one wire in half and splice inline fuse onto that wire with connectors. Next make a one prong connector for each end of wire. Carefully make it so you can plug one connector of wire into the left side of where fuse used to plug into fuse box. Then plug in other wire into right side of where fuse use to connect when plugged into fuse box. use electrical tape if need be so they cannot short across these two wires. Check with amp meter on neg cable and negative batt post to see if meter shows drain. If shows drain... simply switch toggle switch off. Meter should be at zero with toggle switch one way, then shows drain with other. Secure wires with plastic tie straps electrical tap, and duct tape the toggle switch to lower dash board area you can reach while driving. If your wipers or windows etc, aren't working with switch shutting off drain, simply turn on when needed and shut off when you park truck. Recheck with amp meter again when all secure...Good luck all!

Battery drains in two days on a 1969 Chevy truck by the way it's a stock 6 cylinder three on the tree

There isn't any electronics on this 1969 truck , so can't blame it on that. I worked at a Chevy dealer ship back in the Early to mid 80's an saw this problem more then a few times. I remember glove boxes stuffed so full that the light stayed on and drained the battery over night. The vehicle wouldn't start next day an they had it towed to the dealer. I have found bad diodes in the alternator cause this problem. I post a YouTube video for you , beside my test procedure ! To test for parasitic drain on the battery you have to put an amp meter in series on the negative battery cable. This vehicle shouldn't have any drain, yours apparently does are the battery wouldn't go dead. With the meter hooked up start pulling fuses till the meter shows no more drain. How to Find Parasitic Battery Drain If after you pull all the fuses an the drain is still there , disconnect the wire on the back of the alternator and see if that makes a difference ! hope this helps

sounds like you know what you are doing...
Kudos for at least trying to fix it yourself anyways!
Charge the battery and sell it... lol

Battery drain

drain is hard to find it could be a short or a component is staying on. you need an amp meter and hook it up between your battery negative terminal and the negative battery cable.turn the key off and check how many amp is the drain make sure all the lights and doors are closed, dont crank the car with amp meter on it will burn the meter. take each fuse out at a time which ever fuse drops the amps down by pulling it out is causing the drain. find what that fuse is for. check that component and the wiring on it for any shorts.

1988 cutlas siera 2.8 replaced starter, had alternator cheked replaced cps, had coils and modular checked ecm works fine, won't hold charge something draining battery, anything else possible

this is teh generally most over looked problem, 99% of the time the glove box light stays on and you would never see if from inside the car. try removing the bulb and see if that solves your problem

Bypassed wire harness draining battery?

With the ignition switch in the off position, check each curcuit by pulling out each fuse 1 by 1. Use a digital multi meter to check for current drain by pulling the fuse and touching the contacts with an amp meter, if it shows current that is the curcuit you need to pay attention too

If van is not driven for few weeks it would not start and the battery be drained completely, jump starting it still did not help but caused mufler to blew.

to check for a parasitic drain, you will need a multimeter. with battery fully charged, remove negative cable from battery. set meter to 300mA and put negative lead on the battery's negative post. put positive lead on vehicle's negative cable and check meter reading. usually, there's an initial draw for a short time (1 or 2 seconds) for the vehicle'ssecurity system, relays, etc. after that, it should only pull 30-40 mA or so, for the digital clock, radio settings, etc. if you're seeing higher numbers, try removing the main fuses (under hood fuse box) one-by-one to see where the problem is. it's also possible that a diode has gone bad in your alternator, which will draw current when the vehicle isn't running. you can check this by disconnecting the alternator's electrical connector to see if you notice a difference on the meter.

VW beetle battery runs down

Take out the battery and have it tested. Test should show what is wrong with it. If it is too old, then you are in for a new battery.
