Ingersol rand JD 4045

Hi Tony, There are two possible things happening here: 1) there's a problem (low oil pressure most likely in this case) - as soon as you release the key, the alarm kicks in and stops the engine (the key overrides all safety switches). 2) There's an electrical problem - loose connection, bad contact, etc. It could be in anywhere, really. Does the control panel indicate any alarms, or anything like that? Hope this helps - please share more info if you find out anything. Thanks, Cas
