Hi, thanks for the quick reply.

Here is what my HAAS manual say about alarm 134, "hydraulic pressure is sensed to be low. Check pump pressure and Hydraulic tank oil level".

There are three main breakers on the panel, going from left to right

CB4 Solenoid

CB3 Coolant Pump

CB2 Main Transformer.

As soon as the machine goes on CB4 trips

HAAS definition of the CB4 breaker " controls the 115V AC to the air solenoids, 4th axis brake and the oiler. It is never expected to trip. If it does trip, it is likely caused by a short circuit in the wiring on the I/O assembly or the wiring to the solenoids on the spindle head".

So here are my questions;

Could the I/O Assembly just develop a short and if so do I need to replace the entire board.

Second I do not see and wiring going to the solenoids to the spindle head.
When I traced things out there is a MAC solenoid coming from the main air regulator in the back that has to air lines going to the spindle head and I'm in the process of cleaning it and installing a new solenoid.

Failing that is there any othersuggestions you guys may have?


Thanks

Todd!
