I have a Crown RC3020-30 S/N 1A298422 that belongs to one of our customers. It came in with a code -05 as per the manual the TB11- 1 and 2 voltages were checked and were within spec., I also checked the accel. pot and I did not like the readings I was getting and having a new pot on hand, I replaced the old pot and made sure that it was properly centered. I also made sure that the forward and reverse switches were properly adjusted. I no longer have the -05 code or any other codes popping up on the hand set but I still do not have any travel. The A1 contactor is not coming in as well as the F/R A and B contactors. Steer and hydraulic motors both working fine along with all other systems, just no travel. All of the fuses have been checked and the battery is in a good state of charge. I can't help but think that there is something simple that I have over looked.
As a side note this customers operators are very hard on their trucks. They have 2 Crown RC's a Raymond reach and 6 Toyota riding jacks and we have been out there almost every week to repair one or more of their trucks. Most of the time it is something do to them running into or over things. Any help with this would be greatly appreciated.
Thanks.
