    Hi, I've cheaked the alt and I am getting 12 - 15 amps from it when the engine is running is this ok?

    Hi, I've taken the alternator to get tested and it's all good also battery is brand new. When I took off the alternator and placed it back in I seem to be running (from the battery) now 13 amps with engine off and 13.8 engine on so it could have been drive belt! I thought the drive belt was preety tight the first time though but then again it's an old beast and all I've got to cheak deflection is a stick!

    Any idea if this is the proper amp rate it should be throwing out?

Sounds like the 100A alternator fuse, top right of the engine bay (on my N reg HiAce) it unbolts from the back of the fuse box.

If it was me I would take the alternator off take it somewhere and have it tested because it sounds like it has a bad voltage regulator in it

    yes that sounds good for the alternator amps, have you checked your drivebelt? and also check the battery for a bad cell if one cell is bad it will not take a charge and hold it

    the amps are really close it should be somewhere around 14 amps replace your drive belt and look at it to see if it is glaze and if it is then the belt was slipping

Battery dies after several days siting.

Much of the time this is a faulty alternator. It may be charging fine, but when the engine is off may still have a draw on the battery. To start with, you need a test light. Disconnect the negative battery cable. Connect the test light lead to the negative side of the battery and touch the test light probe to the negative cable. If you get a light you have a draw on the battery. that means the battery will be drained in a short time. Disconnect the alternator. If the light goes out it's a faulty alternator. If the light stays on, start pulling fuses one at a time until the light goes off. Do not pull all of the fuses at once! Pull one, if the light doesn't go off, put it back. When the light does go off, whichever fuse it controls is the problem. It's really not that difficult. Good luck.

Alternator light does not go out even when the engine is running,and charging. Toyota Hiace 3L.

Have you checked if the alternator is charging by putting a multimeter on the battery while the van is running it should read somewhere in the vicinity of 14 volts (typically 13.8-14.2). If not reading that or it's higher then that's its saying there's something wrong or voltage regulator on your alternator is faulty or going bad Or could be loose wire or sensor that's giving faulty reading.

1996 toyota corolla, battery & alternator

If the battery has been overcharged then the cells will be damaged . Have a load test done on the battery to confirm failure and if so then get a new battery.. have the alternator checked at the same time because there is a possibility that the regulator in the alternator has been also damaged allowing over charging of the battery. By having incorrectly connected the jumper leads then you may have also damaged the cpu unit of the engine management box. Best have an autro electrician look at it .

1988 Winnebago, not charging at all.

If it is just the chassis battery that is not charging, then the battery isolators if bad. Check the output at the back of the alternator and if it is puttin out, then the problem should be at the battery isolator which is somewhere on the vehicle (most likely under the hood). Follow the alternator output and it will go to the battery isolator. At the battery isolator the lead coming from the alternator should read at least 13.5-14.5 volts and if it does, then check the other two leads coming off of the isolator and they should also read the same. The two leads coming off of the isolator should each go to a different battery and they both should read the same but if not then the isolator is bad. If the two leads coming off the isolator do read 13.5-14.5 volts, then there is a problem between the isolator wiring and the battery somewhere. Check the battery to engine ground, engine to chassis grounds and make sure that they are good. The chassis battery is more than likely a chassis ground so make sure that is has a clean connection. Coming off of the starter solenoid are several fusible links and they could be open(blown). There could also be other fusible links on the vehicle so check around the starter and along the wiring harness. Check the harness for frayed/broken/corroded/ or discolored wires as they can cause problems. If the charging system is working the batteries do not need to be new in order to read the correct charging voltage.

If your charge warning lamp is coming on then you have a problem with the alternator. You need to replace it with a reconditioned item or new item. The charge lamp relay is operating ok because the charge warning lamp is coming on.
Have this done and your battery will stop going flat.

you check all the fuses,including the 30amp fuse or is it 40amp they are not blown none of them,dont take of any leads when the car is running that will definetly short the system. use a volt meter okay. Well if you dont have one use this method then we will trouble shoot the alternator. got a pocket screw driver? you can only do this if there is no cover on the back of the alternator and if it is safe to reach the back of the alternator without falling in the engine. get a sizable screw driver .Tthe middle but area of the alternator produces a magnetic potential, you are charging. now is there a magnetic potential there if yes you are charging if no then you are not as long as its 2 volt above battery there is a magnetic potential and you are charging if it is 1 volt of potential there is no potential and no charging. you basically testing for a magnetic attraction of the screw driver to the middle back of the alternator. so dont remove the leads,here youll know if you need a battery. magnet is there get a battery, no magnet get and alternaor.

First off, DON'T pull battery cable when running. That used to be the way to test charging systems years ago, not these days. Hopefully you didn't destroy your new alternator. IF, you have access to a volt meter, with car running put leads in each battery terminal you should have voltage at 13.1v - to 14.8v, Anything less, your alternator is bad. If it tests ok, then someone either missed a lead on back of alternator or one of wires is pinched.

With the fuse in,and the engine off,start pulling ,relays,one,at a time,the relay that you pull that drops the voltage will be the one that is stuck,this fuse controls the ignition relay.This relay is stuck,and needs to be replaced,by the way,try unplugging the alternator to see if the voltage drops also,cause the 13.5 voltage that was tested on this alternator concerns me,this is not good,really should be 14.25 when bench tested,on the vehicle,with everything on,headlights and ac on high blower motor setting,it should read 13.65 volts,to 14.25 volts at the battery.Now on the bench,it should have read closer to 14.25 volts.If it is any lower than this range,the alternator is not working correctly.If this was at all helpful,please rate,and thank you.

1999 Toyota 4runner starting problem

Turn on the headlights to check the battery and it's connections. If the lights fade out, the battery has likely lost charge, either because of a bad battery, or the alternator has failed. Charge the battery with an external charger overnight if the charger has a low charge rating, then start the engine and measure the battery voltage. The voltage should read 13.5 to 14.5 volts DC if the alternator is working, but 12.6 volts or less if it is not working. The battery should run the truck for a while until you can get the alternator and battery checked. Don't run any accessories until the system is repaired as needed.
