Good evening. I have had this machine for several years and no issues until around 1200hrs. One day it wouldn’t try to start or do anything but throw a code no communication with the CAN. I fixed that by replacing the two relays at the back of the machine by the battery. Now al of a sudden after putting a mew radiator on the machine it won’t start again but the code is 3764 says Engine Controller Main Relay Circuit (Terminal 30). I can’t seem to find anymore fuses or relays that are bad. I need help pls and Case can’t seem to help without saying I need a new harness and can’t find any info online. Thanks
I see no one has responded to your thread. Have you gotten your issue taken care of?
Yes I did. I found a 60 amp fuse in the rear of the machine behind the relay box that was blowed.
Good deal.

Hi Bobby, I'm new to this forum and did something to this machine, Here is what I posted Hi, I just purchased a 2013 SV 300 Skid steer, I left the key on and killed the battery so I put start box on it now no lights, bells whistles, says 3764 code and a fella on here had found a blown 60 amp main engine control fuse that was blown, He said at the back of the machine, I can't find it. Any help would be appreciated. Thank you
