I have a 2001 Patrol 3L Turbo with auto transmission and I recently had a problem with the auto which seems a bit odd and also had the NRMA technician puzzled.

The car had been operating normally and I had just parked it and turned off the ignition, I then tried to restart the engine however it would not start. All the normal instrument lights came on but the engine would not turn over and the starter motor would not engage. I called the NRMA and the technician checked all the usual items but could not find any faults. The problem was eventually traced to a blown fuse (7.5amp) for the auto transmission, I didn't even know it existed. Upon replacing the fuse the engine started but it raised the question as to why it had blown in the first place. The NRMA tech had never seen this problem before and could not shed any light on a possible cause.

The problem may just be a one off incident but I am interested to know if anyone else has experienced a similar problem and whether it is a sign of some other bigger problem with the transmission.

I would welcome any comments / suggestions.

Have a look at a wiring diagram, I'd be interested to know what circuit that fuse was protecting, then perhaps we can speculate as to why the fuse should fail?

Unfortunately I don't have a wiring diagram, the fuse panel just refers to the fuse as being AT Control and the owners manual makes no references to this. I'll search the web to see if any wiring diagrams are available.

Hi Bob

I had this happen to me it was the fuse for the reverse light which is connected to the Auto Tranny circuit. It blew car would not start turned out to be a damaged wire fusing it out.

Thanks for the tiip. I will check out the reverse circuit and fuse to see if there is any faults but it seems strange that I blew the Auto Tran fuse in my case.

do you have anything non-standard attached to the reversing circuit eg, another light or reversing sensors?

My understanding is that if the Brake light circuit fails the vehicle cannot be started also.
This is a so called safety feature.
