Hey all, I have tried searching for about 15 mnutes and get the hated "page not found" error and am at the end of my line, so in advance, I sincerely appologize for this redundant thread cause I KNOW I have seen this info posted before. So
, here goes....
Recently my 95 D-90 tach started bouncing down to 0 and then back up to indicate an accurate (as far as I know anyway) reading of engine RPM. It is intermittent and will flutter up and down as I drive. There is no other indication. I thought I had read it had to do with an alternator connection, and did check those and the connection on the back of the tach. Any enlightenment is greatly apprecaited. Thank you all in advance.
