What should the battery voltage be on a Mitsubishi Galant?
The battery should be around 11.5 to 12.5 volts and once the vehicle is running the alt. should bump your charging system up by atleast 2 volts. It is the volt differential that forces current to your battery to charge.
What happens when the starter on a Galant goes bad?
When a starter goes bad, they will usually not give you much warning first. Also, if you are stuck somewhere and are trying to start your Galant, the old beat the starter with a hammer trick is not a wives tale. It really can get that one last start out of it. There are a lot of issues that can cause your Galant to crank, but not start.
Why does my Galant engine won’t start?
The second way that your Galant won’t start is when the engine turns when you engage the starter, but it won’t fire and run on its own. When the engine isn’t turning over at all, that’s a bit easier to diagnose than when it is cranking but not firing.
What causes an alternator to over charge a battery?
Measure voltage across the battery with your DMM. You should get 0.5 to 2 volts higher than base voltage. If you are getting more than 2 volts above base voltage, most likely your alternator is over-charging the battery or the battery is faulty. Other potential problems are a faulty voltage regulator or a problem in the charging system wiring.
Why is the battery on my Mitsubishi Galant not working?
After several weeks of driving with this condition, the car refused to start. The battery was completely drained. Mechanic tested the new battery and found it to be bad. Replaced with new second new battery. Symptoms disappeared totally for about 2 weeks. Now back to same symptoms of having the battery light come on at start up.
Can a bad battery cause an alternator to over charge?
Make sure that all the connections to the alternator, remote voltage regulator (if applicable) and battery are clean, tight and in good condition. Check your battery or have it tested at your local auto parts store. A bad battery cell can cause the alternator to over-charge the good battery cells.
What kind of load tester does Mitsubishi Galant use?
It is the volt differential that forces current to your battery to charge. A carbon load tester with volt reading is much better for testing batteries or charging systems but the younger techs are usually a little cautious on using them on newer vehicles.
Why does the altenator battery light go out?
Replace the altenator. The battery light is only on when the altenator is not charging your system. After starting the light should go out asap. It’s not so that tells me that the altenator is weak, and once the light does go out I’m thinking it’s not charging at full output, hence the new dead battery.
