Battery overcharging from alternator output

I have a Boxer 2.5D fitted out as a camper. There is the main engine battery & split charge diode to supply on board leisure battery.

I replaced the main battery as old one died suddenly. This has been fine since but recently leisure battery has expelled a very bad spell while engine running. Have checked with voltmeter 16.7 v on both batteries with engine running.

I assume this is to high & is killing/boiling battery. Is there a regulator problem, alternator problem or other. What should I check next?

Battery light on, not charging


Check the wear arrow marks on the belt tensioner.

Belt tension last up to 90K miles.

A worn tensioner will reduce the friction between the belt and alternator pulley.

Fitting a Tec2 relay to protect starter battery


I don't have any info on a Tec2 product, but the basic setup is to put a relay in between the camper battery and the voltage source to charge it. Most of the time the aux battery has a 10 or 12 gauge wire to charge it from the engine alternator and you break the connection with the relay. The relay would be "off" until the engine is running.
Did you get a diagram with the Tec2 ?

Alternator not charging


Possible short to the starter. I had a similar problem with my '91 mercury capri. I replaced the alternator and battery but the alternator would not charge the battery. My local mechanic spent hours tracking it down, but finally found the problem. Have not had a problem since. Good luck

Where is the autonator for the chevriolet matiz


If you meant ALTERNATOR, this is coupled in the mainblet circuit and runs when the runs works. The alternator is the power supply source which produces the charging current for the battery. If produces AC and uses a DC recitifer and regulator to charge the battery with a limiter control so as not to damage the battery by overcharging.
You need to check on the main belt to see this motor- like device fitted to the engine to run along.

Put a new alernater an still over charging


Over charging could be the result of several things including:
    Faulty Voltage Regulator
  1. A car's battery will overcharge if the voltage regulator isn't working correctly. A voltage regulator is usually part of the alternator, and is used to keep a steady flow of voltage to the battery. If the voltage regulator is defective, it will send either too little or too much charge to the battery. If it sends too much, the car battery will overcharge. The voltage regulator is easily replaceable at an easily affordable price, sometimes for as little as twenty dollars, as of 2009.
  2. Faulty Alternator
  3. Sometimes the alternator itself can be at fault. The alternator is the device that converts the mechanical power of the engine into electrical power to charge the battery. When an alternator breaks, it usually stops creating electricity for the battery, which will then eventually die. However, if the wrong alternator is placed in the car, or if the alternator is running at the wrong pace, it will create too much energy for the car battery, causing it to overcharge. The alternator is another easily replaced part.
  4. Incorrect Charger Use
  5. If a battery charger is used to charge your battery outside of your car, improper use of the charger can result in overcharging. If a battery is placed on the charger too long, it can result in overcharging, and a significant decrease in your battery's lifespan and efficiency. This is why it is important to read about your specific battery and understand how long it needs to charge to be effective. Too much charge will lead to problems.
  6. Faulty Battery Chargers
  7. Sometimes chargers can be faulty. Their settings may be wired incorrectly, or the charges labeled incorrectly. As a result, your battery may be getting overcharged, even if you are carefully monitoring your charging. This is a problem that is hard to avoid, as manufacturing mistakes can happen anywhere, anytime without warning. It is a good idea to test your charger regularly to see if it is running correctly.
  8. Heat
  9. Extreme heat in the summer can also have an adverse effect on the car battery. If the battery has been previously overcharged, extreme heat can increase the problems caused by overcharging, and exacerbate any other problems with the battery. This problem can be hard to avoid if you live in a warm climate. The only real way to ensure safety against this problem is to avoid overcharge in the first place.

Need a picture or schematic of battery to alternator wiring on a 1982 southwind motorhome with a 454 chevrolet engine


I can't give you a schematic but i can tell you where the wires should go;Battery post of the alternator should go to the center post of the battery splitter box that splits between the engine and the house.In the alternator plug the wire closest to the battery post of the alternator needs to go to the charge light or an ignition source.The other pin in the plug can just be looped the the battery post of the alternator.If you have no power to the alternator but do have power to the box that splits the power from vehicle to house the you need to put all the wires on the post marked batt until you can get a new one,this should get you up and running.If you are planing to remain camping with the temporary repairs made then separate the wires until you are ready to start the camper to prevent a dead battery condition if the house battery gets run down.Hope this helps.

2001 mazda protege battery overheating - bad smell....., not catalytic converter . 1.6l.


You need to get the alternator output checked. If you can smell something like rotten eggs then what you are smelling is hydrogen gas which is explosive !! Batteries get hot and smell because the alternator is charging at too high a level. Check the output with a multimeter across the battery with the engine running. If it reads higher then 14.4 volts, its the alternator and you need to fix it as overcharging of your battery will cause total failure (if it has not already screwed your battery)..
