All it says on all drawings is Stop magnet for the stop.
I have 2 wires coming from the sensor to the old Tachometer. Will both wire be connected to the new tachometer? I ask since i know from the fishing boat that there are only one wire going from the alternator to the tachometer there. It's just so i know how to connect all this again:-)
Will go offshore later today, so are a bit on/off here, since i will be working nights out there. But will answer during the evening/night.
The wiring for the sensor is normally [ live in - body negative - sensor output ] so two wires.
You should find that you have a wire coming from the ignition switch to the sensor and one from the sensor to the tachometer. The output is normally 5v high / low logic flat pulse. The tachometer counts the changes in state. You will still need to follow the tachometer tuning instructions to set it up.
I have trouble getting the gauge to work correctly. Could you point me out where to connect what wires ?
The reason why is that the sender (1/8npt) might not be the correct resistance, is that possible?
Yes that is quite possible.
If things do not seem to be working as you expect the first thing to do is check your installation.
1.turn on your system and check that power is going to your gauge.
2. check that the negative is flowing freely back to the battery. A good negative is more important than a good positive to a gauge.
3. check that the signal wire is connected to the (correct) pole of your sensor.
For a temperature gauge in a cold system the gauge should be reading zero. If your gauge is reading any value disconnect the signal wire from the sensor. It should now be reading zero. If not your gauge is faulty.
4. disconnect the signal wire from the sensor and touch the wire on to the body of the sensor (not the pole the brass part of the sensor). The gauge should jump up to max temp. If this happened your gauge and signal wire are good if not:
4.1 touch the signal wire on the NEGATIVE pole of your battery. if the gauge jumps up to maximum you have a engine earthing problem to fix. If the gauge did not move then you have a signal wire problem to fix.
5 if the gauge and signal wire are working correctly then you have a sensor issue.
I hope that this helps.
Block connector is a simple and effective way of connecting your panel to its wiring harness. It has the advantage of only needing simple tools to work with it. It is also great when you only want to connect or disconnect one wire at a time.
Robust and long lasting, not water proof but water gets out as easy as it gets in so great when under cover.
Main disadvantage is it takes time to connect or disconnect the whole thing.
This is the one that I choose. Snap lock connectors give you the convenience of being able to connect up a number of wires at once and if the wiring gets wet it will dry out again once conditions allow.
The main disadvantage is that you need a special crimping tool to attach the wires correctly. Though it is possible to use small pliers to do the job.
Superseal connectors can be the best choice for connecting up the wiring on your boat. if they are put together correctly using the correct tools they do a magnificent job. However there are a number of things to think about:
