Hi,
Have an Evolution system with P70, an ACU-200, and a type 1 pump.
ACU and Pump are new.
motor sounds weak and choppy.
We connected the pump directly to a fully charged battery and it works fine in both directions, although it sounds different turning to port.
reconnected ACU and pump and same weak sound
we then checked the voltage going into the ACU and it was 12.6 volts.
we then checked the voltage coming out to the pump and it varies between about 2 volts and 6 volts. we did get 12volts out of it once for a second.
we then checked the incoming voltage under load and it stayed steady at 12.6.
not sure what to check next. It is a brand new ACU but it doesn't seem to be putting out the necessary voltage to make the pump work smoothly.
Thank you
