Why is the rpm reading on my tachometer so erratic?
If you are getting erratic readings, this can be a sign of bad wiring. Another potential problem is calibration issues. If you notice the RPM readings do not coincide with the motor, then it may be time to have the mechanic look at the vehicle. By doing so, they can diagnose any problems that are going on.
What causes a fuse to blow on a tachometer?

A needle that jumps around and shift lights that fire at random may look like a huge problem, but in fact they are usually caused by a simple issue that is easy to fix. First, let’s narrow down the symptoms. Too many times we get emails that just say the tach is “acting weird” or is “inaccurate”.
Why does the needle bounce on my tachometer?
So if the Tach is good, then the jumping or bounce is being caused from the distributor cap to the tachometer? More than likely what it is, it corrosion in the wiring behind the gauge. The gauge needs a good ground to work, if there is corrosion on it, or it’s a lousy ground, the needle will bounce.
Are there any mechanical problems with a tachometer?
Basic Troubleshooting. There are several types of problems that could occur with a tachometer. They can mostly be traced to be mechanical and electronic problems. Of the many car problems that can crop up, tachometer problems are some of the easiest to solve.
How do you connect a tachometer to a boat?
Connect the black tachometer wire to the black ground wire. Connect the yellow wire to your lighting wiring. Connect the remaining wire (usually green) from the tach to the wiring for the engine per your boat’s wiring scheme. Label each wire with masking tape and a permanent marker.
Why is my factory tach not working properly?
The most common problem for tachs is that they get disconnected from the distributor. Connect the factory tach and inspect the wire through the tach filter to the firewall. If you don’t find a problem there, your problem lies in the dash or the tach itself.
What should I do if my tachometer is not working?
Trace the wire connection from the crankshaft attached generator to the display panel on your dashboard. Check the connection with the battery power source and the engine control unit. Make sure that the tachometer is grounded properly. Fix loose connections if any and replace corroded wires.
Tachometers have a “sense” signal on the the “S” terminal that originates from the the charging system. If the battery is not being charged (look at the voltmeter) then that would account for the tachometer not working either. Fuel senders are typically 33 – 240 ohm resistive devices. You need a multitester to verify operation of any sender.
What do I do if my gas gauge is not working?
In most cases, to gain access to the fuel tank sending unit mount / fuel pump mounting hole, you’ll need to drop the gas tank down. Be sure to do this when there is either minimal gas in the vehicle, or it’s been siphoned out.
How does a fuel gauge work on a boat?
On older vehicles or boats, the fuel gauge will usually have 2 terminals. One of these terminals receives 12V of power when the ignition is turned on. The other terminal is the sending wire from the sending unit. The gauge itself is then grounded.
