Review on GXG-1987 Digital Hour Meter Tachometer Tach Tacho: Reliable Tracking for Yamaha Honda Kawasaki BMW Engines by Chris Cervantes

.at 1/4 price. This seller sent the goods quickly. The screw holes are the same as the Tiny Tach. I installed it on my alternator and it showed revs with no issues. Will it continue? Who knows? My problem with the Tiny Tach (and also this one) is that the internal battery cannot be replaced, the case cannot be opened. To my credit, my Tiny Tach lasted 5 years. It can't be this one. This one does something the Tiny Tach doesn't, you can program it to show service intervals. Although the description says the 3V lithium wafer battery is replaceable, upon opening the case I found that it was encased in plastic and coated in wax. After removing them, I found that the tabs were soldered directly to the battery. Spend $4 on a new battery and solder/re-solder? No, I'd rather spend $12 and hope to get another 4 years off a new one.
