Tach Off, Where to Start?

[tracksuit hobo]

Hey guys , has anyone had this happen?

Just bought a 60. The tach is "receptive" at startup, idle, and running, but the ratio is off. It maxes out at 1000.

Checked the service manual, and it says replace.

Loose contacts? Worn out springs inside the unit? What end should i start at?

I'd like to see if i can fix or adjust (and diagnose) something before spending money.

Any info would help!
