Technical Ducato 1996 2.5 Diesel warning light

[TheEarl]

Hi all
I have a Ducato Bus, 1996 2.5 diesel. I have some problems with the electricity in the bus, like this red light that is constant all the time. I have not been able to find out what this light means as I do not have a owners manual.
Is there somone who can help me along here?

Best wishes
The Earl

Hi

Its too bright for me to see its symbol

The glowplug and 'lights on' are the others..


If the oil and battery lights are going off as the motor starts..
And its NOT the handbrake on light..

Then its a bit of a mystery..
Most warnings are yellow


Look towards the top of the forum homepage for 'Downloads' to find a manual

Hi
Thanks for taking the time to answear
There is no symbol on the light.
Plenty brake liquid and cooling liquid. Servo liquid is a bit under the MIN line, so I will fill that up in the morning.

I´ll look in the download thanks for the tip.

Red is frequently used for the alternator warning light.

Given the age of the vehicle, the circuit will be quite simple. A ignition switch controlled 12V +ve is connected to one side of the light. The other side of the light is connected to alternator D+, and hence to chassis via the alternator regulator and field winding (rotor).

With ignition switched ON, a small current flows through this circuit, and helps the alternator to start generating. When this happens the D+ terminal rises to the alternator output voltage. The warning light now has the same voltage at both sides, and goes out.

If the connection to D+ has become disconnected, and shorted to chassis (e.g. alternator casing), the light will follow the ignition switch.

Does the alternator start charging at tickover rpm, or does the engine need revving before the alternator (battery voltage) will reach 14V? This could go unnoticed in normal driving.

Otherwise seek an alternative solution.
