Troubleshooting Diff Lock Issues

[Maxhead]

With the engine running and the diff lock switch on you should have vacuum in that top hose only at the diff.

When you switch the diff lock switch off you should have vacuum in the lower hose only.

Ok,

With the engine running and locker ON there is definetly no vaccume on the top hose.

With locker OFF there is vaccume on the bottom hose
