We have a forklift and it has a fault code 676-4. Glow plugs the spanner symbol is illuminated and a warning sounder is beeping I've swapped the glow plug power relay. And found there is no power from the control at the power relay. the glow plug light is flashing.. obviously it does not start. Also it seems someone has changed the service code as now in countdown and only have 4 choices left. Is there is a controller relay under the dashboard and will the code be deleted automatically if i cure the fault.if someone could help it would be greatly appreciated.
Regards
Jim.
