No, I am not stupid. I just need to read what I have typed befor I send it. It is
about "fuel tahometer".
My concern is that if I need to take off that big board from the assembly then I have
to remve some jumpers and maybe something else. Jumpers are special in the way that
they have wire hooks at the bottom to grab the board. I did not know about that and
when I pulled one I was scared that I broke something.
I am not sure that part I should remove and what parts can be removed w/o damaging
I will appreciate your help.
