Hi. I have now 100 ohms between earth negative wire in and the unit's chassis. No idea how this happened. I had to solder to the next pin down to get the unit fully working again so it connected negative back to chassis of the unit. The back light came back on and eject worked again. I removed permanent positive and connected to ignition positive as it was draining my batteries and i never used the taco but now the mercedes sprinter 411 cd is in limo mode. Then i put it back the way it was but it keeps going into limp mode. Have not tried again since repairing the negative input. Will i have to take this to a mercedes garage if it continues to go into limp mode? Have i unhacked this taco somehow?
Thank you
What was you favourite method to open tacho ? ;)
