How can I Fix my tachometer and speedometer?
The fix for both the speedometer and tachometer was to cut open the back between the plastic threads and very back. I used a dremel grinding wheel. This back circuit board is about even with where the last plastic thread on the outside so there’s enough of a gap to cut safely. As shown in the pic, pull the assembly out a bit.
What’s the difference between a speedometer and a tachometer?
Yours has a different looking back with a different connector style. But I think the procedure would be the same and bet the inside circuit board looks the same. Heck it can’t hurt to try since if you break it, it won’t make it anymore broken than it is now. You have the 204470158 speedometer.
Is the speedo on my Tach still working?
Tach is fine but speedo isn’t working at all. Click to expand… Not the same exact part as mine. Yours has a different looking back with a different connector style. But I think the procedure would be the same and bet the inside circuit board looks the same.
Why does my tachometer only measure 12V?
Also measure the voltage at the ground terminal of the gauge (to engine block), depending on how and where you were using to measure reference voltages. If you measured 12V directly across the gauge terminals, I would tend to agree the gauge is the most likely culprit.

Why is my speedometer going back and fourth?
The crankshaft position sensor will not cause a fluctuation in the speedometer gauge. It can affect the rpm gauge, but not the speedometer. If the speedometer is acting like this then most of the time this is caused by a failure in the vehicle speed sensor. When this sensor or the connection at the sensor fails then this will happen.

How much does a Sea Doo speedometer cost?
Especially the speedo after 13 years. It’s just a shame how many of these gauges must have been thrown out or just dealt with as non working like I did. These speedos aren’t even usually available from dealers anymore. The tachs run $360ish new. Even used, either of these guages fetch $150ish with faded needles and scratches.
When to see a mechanic about your speedometer?
If you feel you are driving faster or slower than what the speedometer reads, it is a good idea to have your vehicle inspected by Your Mechanic, as this might be a problem with the sensor that can be repaired or an indication that the speedometer sensor needs replacement.
Can a bad speedometer sensor cause you to slow down?
A malfunctioning speedometer sensor can also cause a speedometer to act erratically, fluctuating the reading from one speed to another; even though in reality you’re not speeding up or slowing down.
Where is the speedometer sensor on a car?
The speedometer sensor is located inside the transmission and attached to a driveshaft, which impacts multiple functions of the car. Due to this fact, it’s possible that the Check Engine Light will light up on the dashboard if a sensor problem is discovered by the vehicle’s CPU.
