Hello gents,

I have a 94 E-150 with 4.9 inline six. I've been having a problem with a parasitic drain, so I have been doing the DVOM test between negative battery cable and negative battery post. It was pegging the meter. I pulled the #6 fuse inside under the dash and the amps dropped to about where they should be. Fuse #6, according to my Haynes manual, is for the "Accessory tap, anti-theft module, illuminated entry, remote convenience module, speed control - 20 amp".

I don't have an alarm, so I'm ruling out the anti-theft module.

I assume a remote convenience module is one of those keyless entry keychain things, which I don't have, so I'm ruling this out.

What the heck is an "accessory tap"?

Illuminated entry I assume is the lights coming on when the door is opened. Any pointers for checking for a short here?

Speed control - is that the cruise control? How would I check that.

Any pointers or info about these gizmos would be greatly appreciated.

The van runs fine, but my ABS light has been on for some time.. Related? I'm not sure if the cruise control works because I don't use it. I'll check it next time I drive the thing.

 

I don't have any good schematics of a 94 van. I would leave the fuse out first of all, and then see what doesn't work, and if you can drive it like that, leave it out and see what happens. That will be double verification you are on the right track.

If I were to guess, if the fuse also feeds accessory lighting, you might have a glove box light or something like that staying on.

 

It looks like a lighter socket but it is used for charging phones, computers and so on.
Do Not use them for the push in lighters.

Illuminated Entry, Econoline

The illuminated entry system assists vehicle entry during the hours of darkness by illuminating the door lock cylinder (21985) so it may be easily located for key insertion. The vehicle interior is also illuminated by the interior lamps.

Activation of the system is accomplished by raising the outside door handle (22404) or, in vehicles equipped with optional remote entry system, by activation of the UNLOCK button on the transmitter.

This action momentarily closes a switch mounted on the front door latch actuating rod (22152), which completes the ground circuit of the illuminating entry actuator (13C718) and switches the system on. The vehicle interior lamps turn on, and both front door lock cylinders are illuminated by a ring of light. This illumination will remain on for approximately 25 seconds, then automatically turn off. During this 25 second period, the system can be manually deactivated by turning the ignition switch (11572) to either RUN or ACCY position.

The system will be activated every time the outside front door handles are operated, whether the vehicle is locked or not. Opening the front doors from the inside of the vehicle will not activate the system.

If the outside door handle is held up indefinitely so that the interior lamp switch (13752) is continuously closed, the system will operate as normal and turn off after 25 seconds. At the completion of this cycle, if the door handle is still in the raised position, the system will remain off, and it will be impossible to activate the system from the other front door handle until the raised door handle is returned to its normal position. This function is built into the logic circuitry of the system to prevent battery discharge should the outside door handle be intentionally propped up or become jammed in any way.

The system consists of four main components: illuminating entry actuator, illuminated door lock cylinder, interior lamp switch and wiring harness.

In vehicles equipped with optional remote entry system, the functions of the illuminating entry actuator are performed by the remote entry module.

Housed within the illuminating entry actuator is a printed circuit board, the logic circuitry and a relay to switch battery positive voltage (B+) to the various circuits. The normal operating voltage is 9 to 16 volts, but the unit will withstand voltage up to 24 volts for a period of 15 minutes. It cannot be damaged by reverse voltage and is unaffected by vehicle transients.

Fords do not have cruise control, that is a GM thing.
Fords have Speed Control.
You could un-plug it.

No that is an un-related system.

Thanks, that's very helpful. I have never noticed a lighted keyhole or the interior lights coming on with the handle, so I don't think I have the illuminated entry function and I don't have the accessory tap (unless it's really well hidden somewhere), so I guess that narrows it down to the speed control... I'll check all my interior lights to be sure they are going on/off when they're supposed to and then I'll look into the speed control.

I put a quick disconnect on the battery so when I park the van and disconnect it the battery doesn't drain overnight, but it would be nice to have it working as normal.
