![]() 910 forum posts 197 photos | I charged the batteries for my Digital Tachometer that has not been used for a long time. But it wont display the Target Indicator so no rpm readings. The high, low memory screen worked but nothing recorded. It's only a cheap one but would like to know what's gone wrong the Photo Signal red light beam works. Paul |
