Tach Problem

[luckyGAT]

Last week i had to jumpstart the sho with a jumper pack, as soon as it was connected the tach needle spun from 0 all the way around to the needle rest on the other side and just sticks there. Anyone have an idea how to get it back to its normal position ?

This is the best fix of all.
Step 1. Get in the car
Step 2. Put key in ignition
Step 3. Start Car
Step 4. Let it warm up
Step 5. Drive to road with a straight
Step 6. Ring it out in first gear
Problem should be solved
