Got out my test light tonight and found some answers! (1993 Mustang GT Convertible)
I have two fuses that are pulling quite a load. Illuminates the light nice and bright.
HOWEVER....
With both of those pulled (highlighted in red) I would get the light to come on for about 2-seconds, then it would fade out to a super dim, barely on pulse. When I finally pulled the suspect fuse the test light was finally dark! That last fuse is a 20amp marked UNUSED. (fuse 17 in both charts)
Any reason it would do that?
Now for the real issues...
Now depending on what fuse layout guide you use below, the two fuses affect different things. I have no idea which chart is mine or if either of them are. The top one is for a 1993 Mustang LX 5.0 Convertible. The lower is for a 1993 Mustang GT. I have a 1993 Mustang GT Convertible.
The top image contains a fuse that includes Convertible Top, the lower image does not. This makes me think the upper image is my car. --but---It also says that same fuse does rear window defroster which my car doesn't have. Finally, the top chart lists (8) as a Power Window. However since this is obviously a user made chart, I think that's a typo or specific to a 5.0 LX convertible versus a GT convertible. As you see in the lower chart, for a non-convertible GT, reads Power Mirrors. As "power mirrors" is missing from the top chart all-together, this leads me to believe the top one has a typo for fuse 8.
Also the top chart lists CLOCK for 8. Well my radio isn't working with that fuse out. My fuse 11 is still in too. To clarify, both charts state radio is on fuse 11. Top chart also includes fuse 8 for "clock" whereas lower chart says fuse 8 is also "radio." I'm citing these differences as typos or simply the difference between a convertible 5.0 lx and coupe gt.
The facts are with fuses 8 and 16 pulled, my car does not have these functioning...
Door warning chime.
Horn, cigar lighter
Courtesy lamps (although I have no bulbs)
Glove box light (again, no bulb)
Engine light (after market hood, no bulb)
Clock (assuming this also means radio)
Power Mirrors
I don't have any electrical contacts or wiring around the fuel filler door. I also lack a fuel filler door release switch. My car only has one for the trunk. I mention this as both charts say fuse 8 controls this too.
With those two fuses pulled, I have no drain. Test light is dark.
