Question about Ford Explorer

1 Answer

I recently had a new alternator installed in my 2005 ford explorer. The check charging system light keeps going on and off. I understand that there may be loose connections on the alternator and I am looking for some advice on how to tighten the connections. I would rather avoid the mechanic. Thank you!

First, disconnect the negative battery terminal. then there is a alternator output cable which is attatched to the alternator with a nut, covered by a rubber boot, tighten the nut. then, there are 1 or 2 electrical connectors, wiggle the to check for looseness. also, they should not pull out unlees you deprees the locking tab. if they pull out, someone damaged the tabs. or it's possible the alternator is defective.

You need to check the out put of the alternator. In general the alternator should put out 13.5 to 14.5 volts. I would say go to where you bought the alternator and have them check the voltage. If check engine light is on you should have a code get them to check the code. Most auto part stores where I live will check your code for free.

My 2005 ford explorer check charging system warning light


if charging light is on w/ engine running,the fault could be the alternator or another component of the charging system.remove, clean and tighten battery post connections to check for alternator output,use a volt meter or multi-tester set to 50 Volts DC,w/ tester on battery terminals it should read 12 volts W/ engine off;13 to 14 volts w/engine running.if voltage increases when alternator is spinning,suspect battery

12.6 is to low. It should be reading 13.8 to 14.5 when the alternator is functioning properly. Sounds to me like you got a bad connection or a bad alternator. hope this helps. good luck.

Battery light on 1999 Ford Explorer


first, check battery voltage with engine off. It should be @ 12 1/2 volts.
With engine running, it should be @ 14 volts.
If yes, then check for a bad connection at alternator. Look closely at the terminals for corrosion.
There should be BK/DG wire supplying charging amperage to the battery. It does not go through a relay.
Check the mega fuse (175 amp) in the battery junction box (ride side or engine compartment I think). check connection 122 & 197 in same area. good luck

Check charging system


Do you have gauges on this car also?
If so, you may have a problem with what is called a "current shunt" resistor. This will prevent the car from recharging the battery....accordianman
