New here,Just picked up a 863c project and have most everything working.I have the code hp-3 showing all the time.hp-3 shows hyd pressure wire not connected.Traced wiring from hyd. pressure sensor back up the boss and the ohm seem correct at the terminal up there.Anyone have an idea why this code would always show.I noticed when I removed the plug from the sensor it was wet so presumed it was no good but after testing it show good.After this repair is going to be a huge leak at the spool valve.I found a decent write up on that on this site. Thanks in advance
oil in the connector is probably causing the error code, clean the connector, and replace the sender. :drinkup
