Lazy Tach

[prezoom]

Has anyone ever experienced a "lazy tach"? Switched on the headlights and the tack immediately droped to about half revs. Turning off the lights and the tach went back to normal operation.

Chap, could it be a poor earth on the instrument?, switching on the lights will add additional load to the earth as the light bulb in the instrument illuminates hence the drop in shown rpm's - only a thought, but worth a try none the less.

Thanks Glen,

Took a 140 mile run yesterday and the tach worked just fine. But got back before dark and forgot to test with the light on. Still fussing with the little bits, the list is getting shorter, and will double check all the grounds today.
