Hello,
I Have a Older Hitachi machine and I'm trying to figure out whats going on with the pump.
So here's the problem,
On start up you can hear the pump stroke up,
If you try and operate any controls the machine stalls and sometimes shuts off,
the machine wont rev very high at all because of the pump.
sometimes it seems very hard to even start because of the pump.
So I read on some previous thread with people with similar issues on things to try first and so far I managed to check and re calibrate the Angle Sensor to required voltage didn't sense any change in the machine.
I have Volt tested DP Sensor, Solenoids on the pump, Angle sensor and they are all reading the correct volts or very close to it. The pump Computer and main Computer are flashing with no error codes 1 sec on 1 sec off.
I Attempted to try and put it in limp mode but was doing it incorrectly because i didn't have all the details will try again tomorrow. will report my finding if its successful.
