I have a light diesel truck for about a week when I started the truck in the morning the battery light came on for abut a minute or so. I canged the battery the same problem is still there but only happens in the morning when I start the car all day afterwards there is no problem. the truck does almost 300 K's a day and its switched on and off about 30 times but starts straigt away and no light at all. Changed the battery only thing left is the alternator. Anyone had the same issue?

You wasted your money. The battery light is sort of misnamed. It actually has little to do with the battery, but tells you when the voltage is too low, which is an alternator problem. You could take the battery out altogether once the engine is running, and the light shouldnt come on. Before you spring for an alternator, check the ground wire between the engine and the frame. Since the voltage sensor is grounded to the frame and the battery and alternator are grounded to the engine, if you don't have a good connection between the two, nothing will work right.

What you are seeing is the glow plug heating light. Diesel engines do not use spark plugs, they use heat and compression to ignite the fuel (diesel). When the engine is cold (in the morning) you turn on the ignition and that sends a current to the glow plugs, creating a hot chamber for the fuel. Once the engine is warmed up the glow plugs are no longer needed.
Just make sure when the engine is cold to let the glow plug light go out before trying to start the engine, about 1 minute. Try it, you'll see. Turn the key to run, without starting (cranking the starter) and wait about a minute, the light will go off, then start.

Well, is it cold where you live? If so, the glow plugs could be pulling current from your battery and the alternator might not be keeping up with the load. Hope that helps a little.

Ford had a ignition interrupt swap which engaged whilst the motor vehicle replaced into hit in an twist of fate. some have been overly comfortable and must be extra on by skill of going over a bump or the different sharp effect. there's a reset swap someplace on the motor vehicle, in many situations interior the trunk. examine your proprietor's instruction manual. have you ever besides could tried tapping the starter on a similar time as somebody else turns the significant? additionally examine the main significant fuse. the the remainder of the motor vehicle could have potential yet there's a grasp fuse for the ignition/starter circuit.

its possible there is a short somewhere that drains ur battery when u leave it setting over night. take it to get tested at autozone, pepboys, ect. should be free to test and easier and cheaper to replace than an alternator
