Hi all,

My 455 has a problem that I'm hoping you can help with.

Running fine then just died as if it had been turned off.

Went to restart but the fuel pump isnt running and the shut off solenoid isnt moving.
Everything else is fine.

It is an eletrical problem, fuses are fine. Any idea where to go next?

Thanks

i would start by checking if there is power going to the pump.

 

[Mith_J]

No, no power to the pump, I think there must be a problem with one of the circuit boards maybe to have both the fuel pump and the fuel solenoid stop at once.

In order to get home I wired the fuel pump to the headlights and taped the solenoid closed and its runs like that, so no mechanical problems, just electrical.

Check fuses? If it's not a fuse you're going to need a technical manual for that machine. http://www.mytractorforum.com/showthread.php?t=142324

Seat switch would be a good start. What's the status of the interlock lights under the dash?

Thanks for the tech manual, waiting for it to download.

The seat switch is long gone. I do not know about the interlock lights? Are those the little LEDs on the PCD on the right hand side? If so neither are lit.

Thanks

The seat switch doesn't matter.. When the key is turned to Run, the fuel pump starts! If it doesn't and you already verified it is off, there are two 20A fuses on the Power Module under the right side next to the steering column. Check them both. You should see some lights on the dash when the key is on too.. Sounds like either a dead battery or blown fuse to me.. If neither one is the case, the Manual has detailed trouble-shooting procedures for main power in the Electrical section #5 around page 5-27..

Hi Guys,
turned out it was the bonnet switch. It has had a jumper between it and I noticed when I was pulling the side panels off that the jumper had been pulled out (presumably by a stray branch, as it died next to a hedge).
Put it back in and shes working again.

Glad you got it fixed. Ok in the UK I know that 'bonnet' means hood. There is no hood switch on a 455 so I am still searching for what you are talking about .

Hi Harry, there is a hood switch on my 455! Mine is a later model than yours, so maybe yours doesnt have it.
Come to think on it though, there were switches on all the ones I have worked on, so maybe its a UK spec thing?

I saw in the post in your signature about a reverse pedal upgrade. Do you have a link to more details on this?
Thanks

The hood switch is mounted on all european machinery. I have one one my JDx540. If you look in the parts look up ull see a different wiring harnes for export versiones.
More safty switches to .....:sterb003:

I think Evald has it correct. There are no hood switches in the US. @ Mith_J, yes that reverse pedal is a common EBay item with a couple of guys making variations on it. The (2) main variations are adjustable and non-adjustable. Supposedly the adjustable one lets you set top reverse speed, and the non-adjustable one is full speed with it all the way down. I chose the non-adjustable because I am confident that I can control the speed with my foot, and so far I am correct. Here's a link to the seller I bought it from;
