I actually just fixed a probably just like this on my 88' sunbird, it ended up being a link fuse that comes off the starter solenoid (a 14 gauge one), it was broke (ie burnt up like a normal fuse would be when you, o' say hook the battery up wrong). After tearing the whole intake system apart and replacing that wire it worked great, just wish I would have found it before buying two batterys and three alternators. But basically just check your link fuses they should be close to the solenoid.
ALTERNATOR OR THE BATTERY GROUND WIRE Have you tried checking your Alternator? I know this is why mine on my vehicle would not stay charged..
something is causing a drain on the battery when switch is turned off
There is not an alternator indicator light on a Honda Pilot. If the alternator goes out, the battery will not stay charged.
Defective alternator, dead cell in battery, something on pulling power from the battery when the vehicle is idle, corroded battery cable connections, or loose alternator drive belt.
Maybe your alternator needs replacing.
Your battery might be bad, or so might the alternator, or both. A bad alternator will ruin a good battery over time, and vice versa.
The battery is bad or the alternator is not putting out the correct voltage and is bad.
Your alternator is probably rebuilt and not really new. I have had this problem several times and I have bought a new battery and alternator. The alternator keeps your battery charged and powers your electrical system, so even when driving you can lose all power in the car from the alternator draining your battery. Take the battery and alternator to an auto store and they will test both for free. Ask them about the difference in a rebuilt alternator and a brand new one. This is a very common problem.
Your battery does not stay charged. You can take it to a shucks or napa to have it check free. Ed
That light doesn't mean that your battery needs to be replaced. It means that your battery is not being charged while the car is running. Have your alternator tested.
Then something is on pulling power from the battery. Any light on the vehicle or any relay that is stuck closed.
I would suspect a bad alternator and battery, have them both checked at the parts store. A car with a fully charged battery and a bad alternator will run until the battery is drained and then quit.
Take it to your local auto parts chain store. Most of them will check your battery and alternator for free.
The alternator may not be recharging the battery .
Likely the battery or alternator, but probably the alternator
Sometimes even though the voltage at charging is good the battery or alternator could be low on charge or charging low for your vehicles specs.
Alternator not charging battery sufficiently? Check with a voltmeter: A fully charged battery should read approx. 12.8 volts without engine running. With engine running should read approx. 13.8-14.2 volts
You might have a bad battery, a poor connection between the battery and alternator, or a bad ground from the battery.
You have a short - it's hard to be more exact than that, but if you disconnect the battery and charge it outside of the car and it stays charged, you have a short. If it does not stay charged, you need a new battery.
Fist may be steering lock fail at position 2 second alternator not charged to battery ( bad alternator ) i thing diode froom alternator broken
disconnect the positive lead from the battery with everything off. Then touch it gently to the battery post , if you see a spark there is something drawing current
Does your Bat warning light stay on or if you have a Voltage gauge what does it read. Was your battery fully charged before you installed your new alternator? Remove alternator and have it tested to besure that it was indeed the problem.
Check to see if the alternator is charging the battery properly. Use a voltmeter - if fully charged battery should read approx. 12.8 without engine running Should read approx. 13.8-14.2 with engine running if alternator is working properly
