in IRC5
Hi All,

E43 and E44 fans on the back of the IRC5 panel are not currently running, i can not find any information or electrical drawings to fault find further. I replaced the fans for new and they still do not run, should these fans be running all the time?

    Hi, is this a "new" controller. There is a change in the harness. In idle only one fan is running. As soon the motors are switched on and the brake release is engaged all fan's wil run.
