Tach

[hdroyer]

At the Asheville East KOA road today half way back to KOA tach drops to 0. Roll of throttle tach shows RPM's again, roll on throttle about 2000 drops to 0. Coasting down hill shows RPM's 3000 roll on throttle hard RPM's come back. Cleaned the connection on left side

any thoughts what could be hope not the TCI, starts fine idles good.

Your help as always appreciated.

Couple of things ...maybe...the real 1st genners will correct this.....maybe the tci is heating up...some have moved it to on top of the airbox.

 

Or.....sorry to say...it may be the beginning of the end for it.

 

Hopefully there are other ideas out there.

Another possibility is #2 coil, as the tach gets its signal from it. It is acting up or the primary connections for it are loose / dirty. I have had similar, with a loose connection before.
