Helllo, Last night i bumped my apu fan with the trailer
Last night i bumped my apu fan with the trailer (high conencted). About the time I was stopping . This morning I tried to use the apu a/c and got an ACS code. The fan on the rear of the sleeper (radiaotr fan) does not come on. The fan bades were sslightly wedged when inspected. I freed them, disconnected the fan and cond connected it directly to my batteries and it works fine. I reconnected the fan, still an ACS code. I got into the fuse box and found a 20A fuse marked 20A on the board was blown and replaced it. Still no fan, atill ACS code. When I hooked my multimeter up to the wiring harness the fan connects to , and turned on the system, when it came time for the fan to spin up, only measured a .02 to .05 Amp or maybey a .2 .5 i cant remember. Now I am thinking relay? but the box isnt user freindly. it is a tripac , not the evolution. any ideas … read more
