Thanks man. I did reach out to them and that pressure switch came in today. Now I need to find where it goes. Thanks!

Re: '94 CAT 312 AEC issue

Hi Jaybolishes - Have you checked the swing/implement pressure switch and related wiring and connections?  As it's difficult to diagnose based on limited information, we always recommend working with your local Cat Dealer to troubleshoot the system. http://www.cat.com/en_US/support/dealer-locator.html

'94 CAT 312 AEC issue

Hi guys, I really hope someone can diagnose my issue.  When I turn on the AEC, the engine isn't reving up when I use the joysticks.  It does rev up when I use the travel.
