If you decide to get a replacement try the one Inline tube has. This unit is truly a great copy of the original. Whatever you do do not buy the tach from The Parts Place. The guy is known to be cheat and a dirt bag. You will never get any support out of him if needed. He advertises his tach as all US made, a buddy just got one, decided to open it, it has China written all over the parts, one part says "Yinh Yang, China, wires say made in china, plastic display, plastic needle, light plugs wont turn. Claims is exact copy of original!!!! I purchased one part from them years ago and gigot burned. Read all the neg. Feedbacks on ebay. They are scumballs like no other.
