Rotor Tach

The last couple times I attempted to go flying, my rotor tach would not come
up into the green. The engine was at 100% and the phototach showed 520 RPM,
but the rotor tach was not reading right any longer. I spent a while trying
to adjust the gauge but to no avail. I contacted Westach/Westberg with the
problem and they asked "How cold is the ambient air? We have made a mod for
problems with cold temps." I let them know its been between 0 - 20 F the
last month or so here in Pennsylvania. Their reply was "...I would suggest
sending it to us for the temp comp upgrade. There isn't any charge for
this." I don't know if this applies to newer gauges, mine was purchased in
1996. It was quite a pleasant surprise that

(1) it was the gauge and not the
belts slipping or other problem

(2) they had an upgrade to fix the cold
weather problem with the gauge, and

(3) there isn't any charge for the
upgrade.

Yes we all have the cold weather rotor tach
problem. I sent mine back 2 years ago and it's
better but not 100% correct. Maybe they have a
better fix now.
