I have just spent the last hour tracing the hook up wiring on the subs dive tanks I now have one of them working and tomorrow night I will work on getting the other one operational.
I found the easiest way was to strip them back to basics and start over again. I found two wiring errors which I traced to the other tank so I think that one will be less frustrating to get going. Thanks to Jeff and Co for the help with the rear dive planes. I now have to mount the pitch controller so it will adjust easily.
Subs are great fun aren't they.
