Merlo 32.6 intermittent drive problem

[Jonny J]

2014 merlo randomly stops driving sometimes. It will start to judder as you drive along and then won’t move forward or back. Key off and then on again, it might come back to normal and it might not. Some days it will be fine all day and other days it will not. No flash error codes in fuse panel as it happens
Any ideas?
Thanks

Wiring fault to the parking brake release solenoid? Mine did this with similar symptoms.

A 40.7 lost drive with no error codes, that fault was traced to a bad earth behind the dash ,

Every day, Merlo electrical gremlins posted on the forum. I thought Italy had left its poor workmanship in the past, but it still lingers on at Merlo.

I used to borrow a merlo, it did that frequently
Took about 5 mins switched off to clear it.
One day it happened in the middle of town at traffic lights

Remove the panel under the engine and check the wires to the valves on the hydrostatic pump
I think the wires have rubbed

I will see if I can locate the panel under engine and check wiring. I will also remove the panel under the boom and keep an eye on the handbrake to see if it is coming on. Thanks guys. Will keep you posted

What model? And definitely checked for errors on the transmission ecu

It’s a 2014 32.6 kubota engine. I did take the fuse board panel off when it started to do it without stopping the engine at the time and the red light on ecu was not flashing

Panel is right under the engine, wires will be cable tied around the hoses
