This particular model came with defective stepper motors on the back of the instrument cluster. You can buy the stepper motors in E-Bay for a few bucks, the trick is in knowing how to desolder the old ones and solder the new ones on. The whole project should run you about 75.00 bucks. Practice soldering similar materials first before you get the hot soldering gun to the cluster's grid. With some basic knowledge of how solder works, you should be able to fix it in about two hours. You will have to mark the needles at "zero", you can do it by using some masking tape and a pen, before removing the needles. Do some research, and you will find most of the information you need to perform the task. The new cluster will run you about 450.00 plus installation (which is a joke, it is a plug and play). Good luck.
If the speedo works and not the odometer, take it to the speedo shop as something is wrong in the speedo itself. You can't stop the odometer without stopping the speedo.
The speedo or the speedo cable might be broken and, or be dissconncted.
If the speedo stops also, it is the speed sensor. If just the odometer, take it to a speedo shop.
First of all, it is illegal to do so. Secondly, the only way is to disconect the speedo sender, which obviously also stops the speedo so you wont know how fast you are travelling, but that will stop the odometer.
You can use a ratio here, say 40mph/150ft = 80mph/xft then cross multiply: 40x = 150 * 80 40x = 12000 x = 300
wear a jock with a hard cup, or wear tight speedo under the singlet.
Do you mean the speedo, or the fuel guage?
You can remove the speedo assembly and remove the bulb, problem solved. You can remove the speedo assembly and remove the bulb, problem solved.
Disconnecting the speed sensor stops the speedo and odometer. The odometer has to be changed by a certified speedo repair shop.
The logical problem - would be a broken speedo cable. The speedo & odometer are both run from the same cable.
Yes, or it's the plastic speedo gear that enters the transmission. An easy way to narrow it down between the speedo cable or the transmission gear is to disconnect the speedo cable from the transaxle (garden hose style), and attach the metal "key" end to your drill. Then spin the drill. If the speedometer reads like you were driving, then your cable is ok and it's your the gear in the transaxle. If the speedometer doesn't read anything, then your cable is broken and it's time for a new one.
