Question about 2005 Dodge Caravan
I have a 2005 FORD Focus. This has happened twice now both times it was extremly hot. Running a/c on #3 - 4 and after 5 miles on hwy. First time took it to Autozone. They reported altenator puttig out 13.5 amps. So had the battery replaced. Seemed to fix it the first time. Hot day again, late afternoon. A/c on 3 or 4. Driving along on fwy when suddenly gages, radio, a/c, go dead. Car starts to buck and sputter then while trying to exit frw it died. Towed veh hm. Charged batt. It runs. Scared to drive it anywhere because I don't want to be stranded.
Your alternator is defective......have it checked for current output when it's loaded...all accessories on....alternators should put out about 100 amps as an average but it also depends on the state of the battery......the battery actually powers the alternator for the alternator to recharge the battery, so if the battery is bad, it will load down the alternator and possibly damage the regulators inside it....if the alternator is bad then it might damage your new battery......one way to check is to start your car, then remove either the positive or negative cable from your battery...the car should continue to run.....hold the gas pedal down until your rpm is about 1500 and turn on your accessories....if the car dies at that rpm ...then the alternator is definately defective.....voltage output will show 14-15 volts but not enough current and current is whats required for things to work right.....good luck....., the reason for at least 1500 rpm is because alternators don't put out until a certain speed is reached so at 1500 rpm, it should be more than enough for the alternater to produce current.
check for bad or corroded or oxidized connection of all ground and positive cables of the charging system as well.......bad connections cause high resistance to current flow and severly limits current capacity.....loose connections do the same thing......it's a good idea to clean or replace these cables first then try the above.
