Nissan Patrol - Advice on Electrical Problems Required

Hi All,

I presently have a problem with my Nissan patrol 3.0TD (2 months old).

I am not looking to put rubbish on anyone mentioned below, just trying to figure out the cause of the problem to get it fixed.

I have had a dual battery system installed by a well known 4x4 industry supplier (no names given as they are doing the correct thing by trying to resolve).

The vehicle had only done approx 1000kms.

On the night of the dual battery installation, some of the electrics failed on the vehicle, ie dash lights and instrumentation, windows, central locking.

I returned the vehicle to the intaller the next day, who found that a fuse had blown, replaced the fuse and all was working again.

Since the above problem occured, I have a situation where I have a terrible smell in the vehicle (I was told it is a diesel smell) and the fuel economy has dropped to about 20 litres per 100kms.

I did a search on previous posts relating to poor fuel economy, and it was suggested that it could be the air flow sensor. I checked this connection on the air intake, and it is connected.

Could anyone else be able to assist with what the cause of the poor fuel economy could be.

The 4x4 supplier is presently not sure what the problem could be, but will take the car to check over the vehicle next week.

Would anyone have any advice or ideas on what the cause of the problem could be?

All advice / suggestions would be greatly appreciated

Many Thanks
