if you care to take a l(.) (.)k well like a say wdere do a line up on polaris ?or on mag north ? a may have other issues with the mod if a get time a will take some pics of the mod and how that went,but the main concern for now is were to zero the jemred (with the sensor ) ?any help would be great cheers pat I'll take a few pics as that will help cheers now
right a have sorted it out a drilled the bolt and the rod of the sensor was set in it with firbre glass resin the washer that sits under the nut ,was stuck to it and catch in hold of the lost so some times the whole thing would spin and not the shaft so that was the prob its still a bit out but on a full 360 turn its about 00.2so after a full turn the measurement read 359.8/398.9 so its with in .2 like the paper work says that bliddy firbre glass was the prob the beat goes on this as you all no is just one of a million headaches that keeps the fires burning,not only that but a did not follow the mod properly i modded the mod because a did not have the parts,i spoke with me dad again and he suggested that a stick it on the out side .put a wheel on the shaft and let it run on the out side we may do that, yet will give it another go tonight see what happens
cheers pat
