Discussion:
No forward or reverse with 90% full lock

We're having an issue with our little SC4000.
During a turn, in both directions, the forward and reverse stop when the steering is just about at full lock. If 100% is full lock, it stops from 80% to 95%, range.
With no forward or reverse movement. If you take the steering to full lock, motors start again.
They originally suspected the forward / reverse selector gear stick, and replaced the switches in the steering coloum. This did not result in a fix.
They've since checked the steering configuration, and steering sensor.
They are now pointing to an issue with one of the motors.
Any suggestions if anyone has had this issue before would be much appreciated.
