The needle on my speedometer has flipped all the way around, and is stopped only by the peg on which it would otherwise rest. How do I get it to reset?

Sounds like the pin that the speedometer needle rests on at "0" got broken off. If you think you can take everything apart and fiddle some sort of improvisory repair for that pin, then jump in there and have at it. Note that needle calibration may be damaged and it will never read right again, regardless. Otherwise- new speedometer.

Don't think so. Sounds like the battery shorted out, which may have also shorted out your dash/speedo. At this point you can either look into a replacement speedo, or drill a small hole where you may be able to flip your needle back around to proper location, but this will only work if the needle is binding. If will not fix a burned out circuit board

Disconnect the posative terminal then touch the terminal to the posative a few times quickly it will reset your odometer needle to above the resting pin. This happens because you moved your posative terminal and the needles spun around and sat on the wrong side of the pin.

look and see if the needle jumped passed the little pin on the face you might need to remove the lens and pop it back over the pin

if it passes the stopper it has. since they are electronic needles you need to open cluster and you need to correct its position by hand.

first remove negative cable from battery. then remove trims surrond bezel if any. remove top screws, remove inner screws which holds assembly in its place. remove sockets careflully. while you are there you can replace illumination related bulbs too (probably t10 type bulbs and you may try 5050 smd type led bulbs too).

after taking dash board out of car, remove clips holding clear plastic on cluster. correct position of speedometer while thinking you are stopped(since car is off) and do not touch other needles since they may lost their calibration(like fuel gauge).

that is all. installation is in reverse order. remember to clip sockets at back.

Sometimes disconnecting the battery for 5 minutes will cure this. Otherwise, a new cluster will work. A salvage yard one will work also.

u don't rest it, u must remove the speedo and send it out for repair, there is a reason why the needle did this, the electronics have failed that operate the speedometer needle and cuase it to jump over the post, a common problem

Don't disassemble the dash! It will take hours and will rattle from now on. Use a very small gauage of wire, inserted in the odometer reset botton hole, to move the needle back around. It takes a minute or 2. This guage problem usually happpens when the battery is disconnected.

Fuel pump!perhaps not working!sit in car turn ignition on do not atempt start or crank engine you should hear a grunt sound from back seat area like a GRRRRR if not fuel pump not working!

My van did the same thing. Actually the gauge had spun all the way around to the back side of the little peg that the needle rest on. To fix it I took the face of the dach board apart with a screw driver and rotated the needle by hand back to zero and its worked fine ever since..
