I have a 96 ranger and the ignition chime never shuts off. The only way to make it stop is to pull fuse #25 which is gem system and speedometer. What could the problem be? I'm thinking replacing the ignition or should there be engine codes that come up and if so can it be done with an obdII comp or do I need a live dyno done?

check fuses

If the chime includes the cab light staying on as well:
There is a door switch in both the driver and passenger side doors that needs attention. I too had this problem. Solution: squirt wd40 onto the switch located near the door latch on both driver and passenger side.

All this comes from the GEM module,You will need to repair the driver door lamp switch located in the door lock assemble.

there is what they call a chime module . located on the drives side in or near the fuse box by the lower kick pannel . this module could be about 2x2 color black/green/or tan . and look like it has a small speaker grill in it . remove this and it should stop the warning chimes

The gem is shorted out replace it.

You're right - nothing to do with the alternator. Question is, why would those accessories be active with the ignition switch OFF? Perhaps some problem with fuses being active that shouldn't be when the ignition is off.

I am not sure if this right and there should be diagram on the back of cover.

Pulling the fuse is not an option.Check your owners manual for instructions on how to shut it off..

2002 taurus. don't have 2005. Sorry.

Could be your GEM module. Call your dealer and ask if your 2005 has GEM module. It's expensive so be sure it is problem first.

Dealer can test with NGS tool.

CAUTION: Once the new module is installed, it is necessary to download the module configuration information from the diagnostic tool equipment into the new module. For additional information, refer to Section 418-01 .

Principles of Operation
The generic electronic module (GEM) constantly monitors its subsystems for concerns. If a concern is found in one of the subsystems, the GEM will record the concern in the form of a diagnostic trouble code (DTC).
The ignition switch position is very important to the GEM functionality. Erratic or unexpected GEM functions can often be traced to problems with these ignition GEM inputs.
The GEM controls a variety of systems:

• windshield wipers
• courtesy lamps
• warning chimes
• keyless entry
• interior and exterior lamps
• power windows
• parking brake actuator warning chime

Inspection and Verification

1. Verify the customer concern by operating the system.

1. Visually inspect for obvious signs of mechanical and electrical damage.

• Central junction box (CJB) fuse 216 (15A)
• Damaged wiring harness
• Loose or corroded connector(s)
• Circuitry
