Hi AndyPandy
Thanks for your reply, answer no it has standard tyres, iv even checked for anything in the building ie alarm semsors fire alarm or remote doors that maybe spiking the machine all yto no avail. The battery on the truck as been removed and another fitted. The loom and motor cables have been visually inspected with no breaks found. not sure what to check now other than swapping the Zappi Controller and belling out every wire in the loom.
Any ideas greatly received. Thanks
