Hendricks MN | The next thing I would check would be the diodes (little black two prong connector) in the wiring harness. Most of them are under the cab.
Is your oil pressure buzzer off? It should buzz when you turn the key on, then go off a few seconds after starting the engine. The hyd stack doesn't get power until it sees the engine has oil pressure.
If you use another power source remember the head could drop without the engine running.
