I'm not at all familiar with this brand but I'm having problems with the automatic return that has to do with the left and right front drive wheels not wanting to return to normal mode once you put the four way lever back in neutral. It'll return to normal mode when you manually turn the steering wheel. I have checked all the relays, switches and wiring down to the solenoids on the steering valve and switching valve. I don't know were to go from here. The manual doesn't include any kind of troubleshooting guide for anything when it comes to troubleshooting. Can anyone offer a solution? Thanks for your time.
