TC29 tach and hour meter

[tow653]

The tach and hour meter on my TC29 quit working,all other gauges work. Any ideas on how to test? Thanks, Tim

When mine checked out it was a case of mice gnawing through wires. They seem to have a taste for them. Unscrew the cover to take a look and see if it's that simple; if not you'll get lots of suggestions.
