Have you checked the fuel pump.
you can avoid draining the good battery
To charge a rc battery,first find out the battery capacity,Then the out put of the charger. Divide those together and times by 1.5 to get the hours and minutes to charge the battery. Note .15 is 10 minutes.
That indicates a charging problem, The battery light is designed to come on, if the voltage in your system falls below approx 11 volts. I would look for alternator loose wires, broken wires, and/or have the alternator tested. Be sure to disconnect the battery before doing ANY servicing. A bad voltage regulator inside the alternator could be a problem. If it were not charging the battery at all by now you would have gotten a dead battery. If the vehicle battery is also worn out or bad, you could be getting the same results, in which case you need to have your battery tested as well.
After jump starting a car, the battery should run for at least five minutes. You want to get enough juice in the battery before attempting to turn it off.
my best simple guess would be that there is a problem with your battery.... if you can, try another battery and see if that fixes the problem... if not, the problem may lie in your electrical re-charging system, like your alternator or wiring... but, before you replace the battery, clean the battery terminals and terminal connections.
You can try to disconnect the battery for 5-10 minutes but there is a problem somewhere and if the light does go of you will probably see it in the near future again. Best to scan the car or retrieve the codes manually to find out the problem and fix it before anything major goes wrong.
I had this problem with my 1994 Buick LeSabre and it no longer happened when I installed a new battery. It's been at least 6 months now with no recurrence of the problem. Before the new battery, I noticed that if I waited about 5 minutes after turning off the car, I could get the lights to turn off. Seemed like something had to cool down.
If you have recently changed the battery, you may have issues with the key fob operating the locking system. The key fob must be reprogrammed, which you can do yourself first before taking it to a shop.
Disconnect the battery for 5 minutes get the radio code before doing this
First, why was the battery replaced? If there was a pre-existing problem (like a bad starter, for example), replacing the battery will not solve the problem. If, however, the car started fine before battery replacement, then the problem could be that the battery terminals (clamps) were not sufficiently tightened. Don't laugh, but there have been instances where the plastic cap(s) covering the new battery's positive and negative terminals were not removed (duh!). Remove those plastic caps.
Either:-Your new battery is badYour new battery has not been fully charged before installationYour battery terminal clamps are not tightYour battery terminals/clamps are corroded and may need cleaning/replacementYour battery cables are faultyIf all of the above is not the case then you have an electrical problem.
I think you need a scanner to do that, did you try to disconnect the battery for about 30 minutes? That resets everything back to factory settings and my help with your problem
