Replying to: ryanl1217 (Nov 08, 2008 1:24 pm) Running, the alternator should throw a steady 13 to 15 volts measured at the battery. This value will vary according to the temperature and if the battery is discharged. The gauge in the truck is a voltmeter. If it is wildly varying while the truck is running, you probably have an alternator that is malfunctioning. If a cell in a battery is going bad, it could cause non-normal readings on the gauge, which could be either low or high, and could jump around some, but usually will not 'wildly vary'. If you have another vehicle, and can do it, take the alternator out and take it to Autozone, etc - they can test it. Also might take the battery in, you might have got a defective new battery. Of course, there could also be loose/bad/corroded wiring somewhere. The first thing to look at would be both battery cables. Any corrosion showing should be checked. The cables can be 'eaten up' inside the insulation and not visible. Check the connections to the battery posts also, make sure the connections are firm. And the connection where the ground wire is bolted to the block, and where the positive wire connects to - whatever - could be the starter, a relay, etc, etc. And then there are lots and lots of possibilities in the other ignition, charging, etc wiring all over the car. |

Replying to: mmastudent (Nov 14, 2008 6:30 am) Clicking at the 'start' position many times means a discharged or failed battery. The clicking is the starter solonid attempting to engage, but there is not adequate voltage to keep it engaged, it just pops back and forth, and all you hear is a click while it is doing this. If things go dead when turned to the 'on' position - I don't even have a guess. Unless it also is a very bad battery, and it can't even drive the dash lights, etc and you are hearing some small relay attempting to engage, doing the same thing as described above for the starter solonid (which is just a big relay). |

I have a 98 Ranger 4x4, 4.0 liter V6 vin X, My problem is, When the vehicle sits for about 6 hrs in about 40 deg or below temps when I start it (with no problems) all the lights flicker at idle until the vehicle warms up,When I rev it up the flickering stops.But when its about 40 deg or above it doesnt happen...Could this be the alternator going bad or hanging up in the cold. When I put a meter on the battery it shows 14.5 volts when running and 12.5 when off....Any ideas,,Thanks

1994 Ford Ranger XLT dome light will not turn off and the open door or seat belt chime keeps beeping. Every so often, this happens, but it has become more frequent recently. 1. Dome light comes on when door is open, but will take a few minutes to go off after the door is closed and the engine is started or it will not turn off at all. I noticed a surge the light gets brighter when I start the engine. Also, the light remains on even when the truck is not running or idle and all doors are closed. 2. The door/seat belt chime also will not turn off. This is very annoying. 3. The head lights will turn off while I'm driving and come back on after a few seconds. Finally, the ignition switch may play a role in this mayhelm, because it is loose and sometimes this stops the chime, but only when the engine has been turned off and I move the switch to a certain position. If anyone has experience fixing the above problems please drop me a line. A ford service personnel says it might be the Door Jam Switch or Multi-Function Module, and the Head Lamp Module may be bad. To Fault Trace these problems will be very expensive. Can someone suggest a less expensive solution?

Replying to: bolivar (Jan 06, 2009 10:53 pm) Where the switches located inside the door panel? Any info about the head light problem?

Replying to: kristij (Jan 10, 2009 8:25 am) In later years, the switches moved inside the door, on the outside door handle pull mechanism. To completely get to these switches, the inside door panel must be pulled off. Sometimes relief can be gotten by liberally spraying WD-40 or electrical cleaner through the outside door handle 'slots'. These inside switches seem to give more grief than the older type. For mid/late 90's Rangers, they have common complaints about inside lite not going off, door open chimes dinging, etc, etc, etc.
