![]() The pot on the left (# 245885C93 ) works directly with 16XX combine (and service bulletin indicates the same for 14XX but I don't have one to confirm that ) A case service bulletin I have indicates the same ("essentially this adapter switches the power and ground terminals in the pot so that the AHHC will function correctly" ) I have read elsewhere that this adapter also has diodes in it that slow down the signal rate but service bulletin does not mention this and since I don't have one I can't say if just switching power and ground works as well as the adapter would. replace the pot you have with pot # 245885C93 (the pot on the left in the picture ) or add an adapter (part # 434795A1 ) I ran into this issue on our combinations and was going to order this part but a tech at dealer told me not to bother and just switch the power and ground terminal in the connection to the pot. If you have a 14XX or 16XX combine and have a 1020 with either of the above mentioned pots ( 127360A2 or 86616339 ) you have 2 options. the field tracker on the head we have used the same pot on each end (# 86616339 ) this pot works with 21XX and 23XX combines directly, just hook up. ![]() I don't have field tracker on our combines but the 30' 1020 I have came equipped with field tracker. in the picture it is the clear / Amber pot on the right.ġ020 1995 and newer than the above serial number and 1020's updated to the mechanical linkage (non cable ) use pot # 86616339. The following is what I have come up with.ġ020 1995 or older pre serial number JJC0215001 with the cable linkage when used on a 21XX or 23XX need the pot # 127360A2. I think it is the pot on the left ( #245885C93, and this pot works with my 1680 with factory AHHC. I do not know what type of pot was used on the pre 1995 1020's originally as none of the 1020's we have owned have had the original pots on them and service bulletin documents can be confusing (for me anyway ). I THINK I understand them now but if I have something wrong please let me know. Thought I would post a pic of the 3 versions of potentiometers and their part numbers and what I think is the correct combinations of header / combine / and pot. Posted 10:30 (#6265206) Subject: AHHC / Potentiometer review (14-16-21XX CIH combines)įairly normal to see questions posted here regarding header height control and I struggled getting our 1680's and 1020's working properly as it was all new to me.
