Post Subject: Failed TachometerTony, I have what appears to be a failed tachometer. Before I shell out for a replacement, could you suggest a few simple tests to determine if anything else is wrong. I have checked all obvious wire connections to the back of the panel and from the alternator. The engine is a Yanmar Barrus Shire 1200 type 3TNE78A supplied in 2003 on a steel 45ft narrowboat. Perhaps a clue: The tacho needle has periodically stuck on 1000rpm when turned off. Hope you have enough info to help. Thanks Tony
