Hi Corvan, thanks for that good info. I have found the switch and it worked all my alarms are now working. The reason I missed it was because i ran my mouse along the switches and none came up with AWS. Now I know it was the 24 volt switch with a label underneath saying AWS, which when I got close enough could read it. Thanks again made driving the Class 66 a complete experience.
I haven't actually looked at the manual, just gave the cabs a thorough examination. That said, I did once accidentally press the Engine Stop button in the Class 66 really quickly thinking it was a DRA switch. Couldn't get the thing going again afterwards, that ended that service.
Download and read this. I have printed it and put it into a binder. https://drive.google.com/file/d/0B5xmS3GoYKV1RHc2Y3UtQ3VQN28/view
