10 days+ i drove the van to a town 60miles away.,on the way i notice the alt was reading low about 8 v. i went to autozone, had the batt and alt checked.. was told the batt good alt bad. now the fun starts. get the alt ,get home change the alt,and charge the batt. crank the van some problem no voltage to the batt from alt.,.,? what do you think?
There is a fuse or fuseable link between the alt and battery, and the alt gets a signal from the key to activate the voltage regulator.
I would check for batt voltage at the alternator and you may need a wiring diagram to check for key voltage.

I have had a string of bad alternators through my shop lately all made by USA alternator. I would breakdown and get an OEM part in this case. I would also bench test alternator prior to installation

14.6 means your voltage regulator or diode is suspect Despite having new alternator .Ive cross refrenced your smptoms in the haynes workshop manual and alternator is your only end answer.The haynes test is to start vehicle with multi meter connected across the battery terminals,increase the engine speed until the reading remains steady should be approximately 12 to 13v and no more than 14v.switch on as many accessories as possible(headlights heater blower radio etc)check that the alternator maintains the regulated voltage at around 13 to 14v.If the regulated voltage is not as stated then alternator is to be repaired/replaced.Good luck with it and a happy new year.

I have a corolla and had #4 cylinder misfire also diagnosed at autozone. After changing the spark plugs, problem persisted, along with the same error code, so they recommended changing the spark plug wires, and that is what fixed it. I would have changed the rotor cap too, but was low on dough. Glad that was not the problem.

Hi. this is defiantly a slow or major drain that is occurring within this vehicle. Here is a test that you can preform that will help you find this battery drain so you can illuminate this issue.
--BATTERY DRAINAGE TEST PROCEDURE--
Using a 12-volt test light, hook one end to the negative battery post the other
end to the negative battery cable you just disconnected. The test light will glow
or "light" if there is a drain. If the "light or glow" is faint, that is probably
normal draw for the clock or computer. If the "light or glow" is bright, then there
is a large drain. That should be corrected. Now start removing and replacing the
fuses one by one until the light goes out; that one will be the circuit with the
drain. Remember to hold in the button in the door jam for the interior lights.
Please rate and god bless:)
