Hi gents thanks for the info. Got problem sorted today. Turned out that a the truck had a steering fault originally and that the steering card had been changed proir to me getting there. On checking the steer card I found it to be the wrong type. A steer card and a steer pot later the truck was back in action.
whats the controller type ? have some info
Hi mate, battery is fine under load and key s/w supply is good. the truck is an etv216 2004 model. Which controller do you suspect might be faulty?
HI Mate
If battery is good under load. If key switch and supply to the controller along with all supplies are checked and found to be ok, then its possible you have a faulty controller.
What is the truck you are working on? Model?
1 Low voltage during system start
Check battery voltage, chargebattery;
Checkwireconnectiontocontroller;
check main current fuse; check main
contactor; replace control part;
Replacecomponent;
