2001 mustang v6 automatic convertible keeps blowing fuse #10 (park, tail lamps)

IN THE FUSE BOX. (CAB OR BAY_)
THE OLD USERS GUIDE AND THE SERVICE MANUAL COVERS FUSES.
PARKS = TAILS
PARKS ARE FRONT REAR. BOTH
SO ARE BOTH ENDS OF CAR DEAD FOR PARKS?
THE FUSE IS MARKED "TAIL"
AND RUNS ALL 10 PARK LAMPS ON THE CAR.
THE PARK FEED TO TAIL OF CAR PASSES TROUGH A LIGHT FAILURE SENSOR ON 4 REAR TAIL LAMPS ONLY
THE SENSORS IS OPTIONAL AND NEEDS FUSE "GAUGE" NOT BLOW TOO., THIS OPTION SO FITTED, HAS CLUSTER LAMP CALLED
"REAR LIGHT " WARNING

REPOST AND TELL WHAT ALL 10 PARKS DO.
OTHER WISE HUGE WORK DOING THE HARDWAY

FRONT, REAR AND SIDE MARKER ARE ALL PARK LAMPS
THE LEGACY NAME TAIL IS STILL USED BACK TO 1920.
SO IS A TRADITION BUT BIG TIME CONFUSING WITH 10 LAMPS.
LIKE SAYING MY FRONT TAIL LAMPS ARE DEAD., SILLY.

Park, Tail and Marker Lamps
The park, tail and marker lamps, including the license lamps, are turned on when the headlamp switch is placed in the PARK or ON position or anytime the headlights are requested. The PARK LPS 30 A fuse in the engine wiring harness junction block supplies battery positive voltage to both the park lamp relay switch contacts and the park lamp coil circuit. The body control module (BCM) provides a ground or control circuit to the park lamp relay coil circuit. When the park lamps are turned on the BCM energizes the park lamp relay. Current flow is from the park lamp relay to the FR PRK 10 A fuse, RR PRK 10 A fuse, LR PRK 10 A fuse, and the TRL PRK 15 A fuse, and to their respective park and marker lamps. The front park and marker lamps are grounded at G100. The rear park and marker lamps are grounded at G401. The license lamps are grounded at G401. If the headlight switch is left in the ON position, the inadvertent power control feature will turn off the park, tail and marker lamps approximately 10 minutes after the ignition switch is turned to the OFF position. If the driver places the headlight switch in the ON position after the ignition switch has been turned OFF, or if the ignition switch is in the ACCY position, the park, tail and marker lamps will remain on until turned off or the battery runs dead.
The CTSY LMP 15 A fuse in the engine wiring harness junction block supplies battery positive voltage to both the inadvertent power relay switch contacts and the inadvertent power relay coil circuit. The body control module (BCM) provides a ground or control circuit to the park lamp relay coil circuit. When the driver presses the cargo lamp switch, the BCM energizes the inadvertent power relay. Current flow is from the inadvertent power relay to the cargo lamps. The cargo lamps are grounded at G203.

There is an issue, you have a dead short in the circuit, no quick fix for this. You must first get a wiring diagram of the entire circuit and then follow it until you locate the shorted wire or component.

they are dual filament bulbs so the tail light filament might have blown and not the stop light , replace the bulb to check

no (park -tail-running lights) is dash parking lamps glowing?
check the tail fuse yet?
94 accord
this circuit is huge, park/tail, up to 20 lamps. are all dead>?
front park, side park, tail park and dash lamps all out.
this i the red-blk feed. all comments , USA, as lighting varies by country. (laws)
license plate light dead too????????? that too is park
there is NO RELAY.
the fuse 32 feeds the HL (head light) switch and in PARK posistion
it feeds 12vdc raw power to all 38 lamps. (side corning lamps,etc)
the license plate lamp is key, there are 2 lamps.
and both probably are not out.
so if they are good lamps and both tail lamps are good and fuse
then they must glow, if one lamp shorts as 1156 or the like love to do
then it blows the fuse. as does the trailer jack (option) .

so fuse 32 park/tail blown
or HL park switch bad, if all 20 odd lamps dead. and fuse holds.
that simple, and this cars wiring is very simple and nice.

Daytime running lamps control module. Fuse #37 - inside the passenger compartment or under hood fuse box ? Do you know how to use a volt meter an wiring diagram to find electrical problems ? You have a direct short to ground or fuse #37 wouldn't blow. Underhood fuse box fuse # 37 is for the park lamps .Supply's B+ voltage to the daytime running lamps module an the headlamp switch plus 37
PARK LP Fuse
20A
Headlamp Switch, Body Control Module (BCM), and Vehicle Interface Unit (VIU)...
Park, Tail and Marker Lamps
The park, tail and marker lamps, including the license lamps, are turned ON when the headlamp switch is placed in either the PARK or HEADLAMP position, or anytime the headlights are requested. The PARK LP fuse in the underhood accessory wiring junction block. When the headlamp switch is placed in the PARK position, battery positive voltage is applied to the park lamp circuit. The parklamp circuit then applies battery positive voltage to the DRL control module and to all the marker, park and tail lamps. The front park lamps are grounded at G101. The rear park lamps are grounded at G302. The license plate lamps are a part of the rear park lamp circuit and are grounded at G302 The inadvertent power control feature prevents the park lights from remaining on more than 10 minutes if left ON. If the park lights are turned ON after the ignition switch has been turned OFF, or is in the ACCY position, they will remain ON until turned OFF or the battery runs dead.

Just talking about tail lamps, did you check the fuse? Not only check the fuse, use a test light and check voltage on fuse circuit. At the tail lamps, the brown wire is voltage, headlamp switch on. The black wire is ground, check them both. You can check ground with test light, one end of test light touch battery voltage, the other end touches the ground wire terminal, if the light comes on, the ground is good enough to turn on the test light.
Usually the first thing you do is check voltage and ground on this circuit before changing parts. Just my opinion.

Park, Tail, Marker Lamps, and License
The park, tail and marker lamps, including the license lamps, turn on when the headlamp switch is placed in either the PARK or the HEAD position, or anytime the headlamps are requested. The RT I/P #1 fuse in the RH I/P fuse block supplies battery positive voltage to both the park lamp relay switch contacts and to the park lamp relay coil circuit. The park lamp relay coil is controlled by the body control module (BCM). When the headlamp switch is placed in the PARK position, the BCM energizes the park lamp relay coil control circuit.
Current flows from the park lamp relay switch to both front and rear park lamp fuses and to their respective park/tail lamps. The front park lamps are grounded at G101. The rear park lamps are grounded at G302. The license plate lamps are a part of the rear park lamp circuit and are grounded at G302. The inadvertent power control feature prevents the park lamps from remaining on more than 10 minutes if left on. If the park lamps are turned on after the ignition switch has been turned OFF, or is in the ACCY position, they will remain on until turned off or until the battery runs dead.

Did you the REAR PARK LP fuse 15 amp in the right insturment panel fuse box.

Not sure which fuse you checked.
The Engine Compartment Fuse Panel ( Battery Junction Box / BJB ) is where the fuse is for the trailer tow adapter parking lamps.
Fuse # 5 is the fuse for the parking lamps, and the reversing lamps.

Next is the trailer tow adapter park lamp relay. This is what BJB Fuse #5 feeds, and the coil is operated by the truck's parking lamps. This is also in the BJB, Relay 201, it is the 1/2 size relay.

Not sure what you took a resistance reading from on the trailer tow adapter.

If you want, you can pull the trailer tow park lamp relay, and jumper the normally open contacts, which should provide power at the trailer tow adapters, regardless of the truck's lights.


This is the wiring diagram for the trailer tow park lamps

the wire is obviously pinched. Try removing both tail lamps and check that the wiring did not fold and pinch when lamp installed.If recent bulb change, the wrong bulb could do it. And check the filament of the bulb for breakage and falling against post. Second most likely area of pinch is at sill plate @ door opening.
