Sticking Tach
so i finally got this new dash put in, and the tach either wont go higher than 1500 or gets stuck above 2000 and will hardly move, even when the engine is turned off, it stops at 2000 and wont go to zero
 any ideas on fixing it?thanks for any responses 72afr

If it is OEM Tach it may be metal debris on the magnet. The needle sweeps close to the magnet and metal shavings prevent it from moving as it should. I used a fork and removed the needle and disassembled and cleaned mine and problem hasn't reoccured (this was approx 6 years ago)
