Question about 2000 Mitsubishi Diamante

1 Answer

Battery not charging sometimes, drains out while driving

Battery not charging symbol shows and drains out in few minutes while driving, this causes jerks or sometimes vehicle turns off. But sometimes if I pull aside and keep accelerating, all the lights including speedo meter blink and when battery drains out completely, it restarts charging and all the lights come back working fine.
When it dies and if engine turns off, giving a jump start restarts everything fine. This is very frustrating and not sure when it works and when it does not.
Please advise

    Can get it started and by keeping the revs up it sounds ok, but when I back off the accelerator it dies. Have even tried taking it for a drive till it gets to temp. Drives fine, but still will not idle when I pull up at an intersection.

Battery drains


Assume you mean drains of power not fluid. Does battery light show on dash with engine running. Make sure that the alternator drive belt is correctly tensioned (longest side betwen pullys move 1/2" up/down). If it takes a few days to loose charge temp fix is to use a solar battery charger that can charge battery when car is parked. Hope this helps.

Hi I bought a new battry and it showed green for a week now it does not show green but car starts must it show green every day


Generally the indicator should glow green for the life of the battery unless it has drained or failed.

If you generally drive extremely short distances (under 15 minutes per trip) you could be draining the battery whenever you drive. This is a common problem in city cars. Otherwise it's possible something is faulty in the charging circuit.

No light can come up including ignation key


check vehicle battery connections for obvious corrosion. If none is present, use another vehicle and battery jumper cables-properly hooked up, and with 2nd vehicle idling, try cranking Toyota. If not immediately starting, give it a few minutes to charge toyota battery, and then try again. A fully drained battery will require several minutes charge from second vehicles charging system to sufficiently charge drained battery.

Battery drain in a few minutes


Sounds like alternator (generator) is at fault. Voltage at battery should read about 14 volts when charging. Sometimes onlythe regulator (diode pack) on alternator is at fault some can be changed without having to have a new alternator (not sure about yaris)

2003 Mitsubishi Galant 2.4L 4-cyl is having trouble holding a charge on the battery. Tests say battery and alternator is OK. I checked fuses and they were good. I can jump the car but after I drive it...


Most likely you have something draining the battery. Quick way to tell, disconnect the ground (negative) cable to the battery, let it sit for a few hours, then reconnect it and try to start it. If it starts OK, you know the battery is holding a charge, but something is draining it.
To drain it in just a few hours requires a serious draw, like headlights or the cooling fan. It is possible that your cooling fan (behind the radiator) is staying on all the time. Often they are controlled by a thermostat, and will run for a few minutes after you shut off the engine, but it should shut off within about five minutes. If it is still running after ten or more minutes, you have a bad fan thermostat or a bad fan relay. If that is not the problem, you will have to get someone with an ammeter to measure the current draw, and start pulling fuses until you find the culprit.

1983 honda accord alternator not charging the battery. drains after few minutes


Sounds like you regulator points are staying closed, thus causing the no-charge condition as well as the severe drain on your battery. Check the fusable links, the ES1 and ES2 motors were famous for this in 82-85, but if they are fine, replace your alternator.

Not starting, clicks


Check and clean all connections to & from battery, as in the other ends of cables as well. Make sure starter wires are all in good shape & tight as well. When you hear that click, try to locate area or relay doing the clicking. It may just be a faulty relay. Sometimes it's as simple as removing it and plugging it back in to clean the connection. Do you by chance have a 12volt DC test light to test draw on battery?

Tricky ... Was the alternator replaced with a 2nd hand one or a new one?

A defective alternator can allow the battery to discharge within a few minutes (the diodes in the rear of the alternator can burn out and cause the problem. The diode pack can be replaced). When this happens recharging the battery only replaces the power in the battery - which drains straight back to earth via the alternator, flattening the battery again - often within a couple of minutes or less.

Does the battery lose its charge when the car is standing or just when the engine is fired up?
If the battery loses its charge overnight, try disconnecting the wiring from the rear of the alternator (also look at the electrical connector that fits into the back of the alternator - look for melting/burning marks which suggest something may be amiss inside the alternator).

Let the car stand overnight with the alternator wires disconnected. Will it start up ok and drive (with the alternator wires still disconnected) the next morning?

You could also try just disconnecting the alternator wires, firing up the car and then driving it -
If the car drives ok without dying out and gets further down the street than it usually does, then it probably is the alternator at fault. The car should drive until the battery drains and has insufficient power to trigger the ignition. You certainly would get further down the street with a charged battery and disconnected alternator than you currently do.

It does sound as though you've had an alternator fault to begin with. If it has been replaced with a 2nd hand unit that unit may also be faulty. Rather than replace parts in desperation, visit an auto electrician's - within a few minutes they will be able to test the battery/alternator output and also identify where the lost current is going. It will be cheaper in the long run to have an auto electrician look at the charging system. It only takes a few minutes.
