Along with the battery woes, about a month back I noticed that my AutoMeter tach was reading about 300 to 400rpm low at cruise speed with the error diminishing as rpm decreased, only off about 100rpm at idle speeds. I talked to AutoMeter, they convinced me to send it in to be checked, and they found it to be out of calibration, but also out of warranty - I purchased the gauge set in March 2010 for the build, first calibrated the speedometer in November 2010, so even considering the "first used" date I exceeded the one year warranty. $25 plus $13 shipping brought me a re-calibrated tach and all was good. That is, until we got 30 miles into the Springfield road trip and the tach dropped from 2000 to 1500, then to 1000, then to 500rpm all in about ten seconds. It bounced around in the 400 to 800 range for about 100 miles, and then started a liesurely climb back to 2000, and seemed to be dead on for the rest of the weekend. As we left Springfield it was fine for about ten miles, then lost about 500rpm and stayed there for most of the trip. As we neared home it again seemed to regain accuracy.

It's on its way back to AutoMeter today. I explained that I was already into the repairs about $40 on a $100 instrument, and they've said that if they find it to be bad they may offer a replacement at "a significant savings", so I decided it was worth the $3 USPS Priority Mail charge to see what they say....
