Central iowa | I think your assumption is correct but id verify few things first. What are voltage on the ccd link ( known as can bus on newer models) because it could be your terminators but most likely you are correct on the ccu being the problem. Dont have the book in forn of me but yellow and green wires should be around 2.3-2.7 volts but also check the red power and bloack grounds to terminators as well. Check your input voltages to ccu as well. I've opened up controller wedge boxes before and found the circuit board has a green spot from corrosion on the silver circuits ( little confusing because board is green but the corrosion is different color green). If have another 4710 around you could swap ccu and see if it switches machines with the ccu but guessing they are few and far between in your country. | |
