Without a proper resolve of this difficult trouble shooting issue, in my opinion, future buyers of the FGT will bid down the buy price accordingly to reflect the uncertainty over the seemingly staggering amount of time and trouble, not to mention money to correct the problem. Gosh, every time you turn the key on now, there is that fear that the gauges are going to malfunction. I read earlier that the aluminum frame may be responsible and in the meantime, it seems like throwing new parts at it is the only way to try and correct the issue. Hopefully the pros on the forum here will do just that for the rest of us, and for that, I thank all of you in advance.
