patrol does not start.

[PaulM]

Hello everybody,

It's about my good old Patrol Y61 (GR 2,8 TDi).  Model for the European continent, 1999

After a long trip to Swedish Lappland and medical troubles the Patrol was not in use for many months.  So, I installed a new battery and tried to start up.

Didn't take a second and the Patrol was alive.  So, I thought : I'll let it run for 15' or so...

When I came outside the engine had stopped.  No way to start it up again...

My first observation was that the indicator for the glowing did not work so I checked the fuse : OK, then the glowing relay : OK.  The fuse does not get any signal.  Next thing I remembered was that there must be a signal from a heat-sensor (I didn't check this yet because it's dark here at this moment) and a glowing timer.

Now it comes to the problem : I don't find anything such as this glowing timer.  Can somebody help me ?  (We have the steering wheel on the left in driving direction, so I will stand and look from the front towards the engine).  The only thing I can think is that the glowing time is controlled by the CPU, but on the other side I see that there are spare parts called "glowing timer relay"...

I just found out that fuse nr. 47 is blown... a new one was blown immediately.

This is responsible for "charge" (electrical scheme), what's does that mean ?  On the fuse box is mentioned "engine control"...

Other information leads to "generator"...

 

Ohm measurement between the out the fuse socket and 0 V reads 800 Ohm, changing the probes gives a 1, meaning : no connection.  Makes me take about diode-problems in the alternator (during my trips in the Icelandic interior I've been through deep water hundreds of times).  Regulator ?

Glow relay is directly controlled by engine ECU it grounds the relay for its timer operation....  Positive supply is for both actual glow power and control from same fuse 100A.
