SC TACH STICKING

[lendaddy]

Hi guys, I got what I think is an easy one this time. The tack on the SC works sometimes not others. Alot of the time it will stick at like 3500 RPM or so. I am guessing it is an internal tach binding or something(it sat for years). If the sender was bad would it not just go to zero or can the sender give signal lock as well? Thanks

Mine did the same thing. When I called Palo Alto Speedo to get my gauge faces color changed and all of the gauges check out. They told me that the sticking was common and cheap to fix. Those guys did a great job for me, Pelican also does gauge work.
