david nelson Posted November 3, 2007 Posted November 3, 2007 Just put my DL1 logger back in and when the electrics is switched off you can see a slight lighting of the logger lights. If i remove the tacho feed not lights show and the units is off. Does the tacho feed alway have a current ? David
Julian Thompson Posted November 3, 2007 Posted November 3, 2007 Sounds like a poor earth - the tach might be acting as an earth with the backfeeding current. Check the ground to the DL1
