I have a cat 420f2 it serial number 0420FLLYC00218 ride control not working. Initially blew a couple fuses the last time I replaced the fuse ride control stopped working again but the fuse didn’t blow. Now when the ride control is turned on I hear a clicking in the relay when I go over bumps it seems like the ride control is trying to activate but the bucket doesn’t move just continuous clicking coming from the relay. Could this be the relay? Machine only had 650hr
