Hi roshan. Zha,

What is the make, model and year of the vehicle?

What is it that you want to do? Install a tachometer?

Hello Sir, I am designing one wireless system by which vehicle owner will come to know that his/her vehicle is running(ON) or OFF.
vehicle is Dump truck of Hyva-ashok layland India

sir, I dont want to insert any device like Tachometer because it should be automatic. Is there any wire in ignition system which will deliver voltage as long as engine is ON? or is there any other way around?

Hi,

No, the ignition switch wires cannot be used to monitor if the engine is running.

The few items that you can use are :
1. Charge indicator circuit. If alternator fails, this would not work.
2. Oil pressure circuit If pressure switch is faulty, it would not work.
3. Engine rpm which for diesels needs special adapters if vehicle is not equipped. This would be the best system to use.
4. Engine vacumn. You can attach a vacumn switch that works when engine is running and this can be used to connect whatever warning indicators.
