Hello folks! I have an 830 ck diesel and the tach is inop. I took the cable loose from the block and the shaft is spinning. The problem is that the shaft the square end of the cable slides down into seems to be too big or wollowed out. I have tried the new cable with no luck. I have heard some talk about this problem and they have used tin foil or built the cable up with solder. If it can't be done easily can you put the tach adaptor to the back of the generator and get a longer tach cable? What are any of you guys ideas? I fixed the ground speed indicator with a cable but I would really like my tach to work☺ Thanks in advance for you guys wisdom. Nick
