I have had this unit for 3 or for years now. Give-up on it........fight with it.....give up........now trying to figure it out again.
When
@Mattax showed the bad soldier job on his socket and i found similar problem i was a little excited(fighting it for so long didn't get my hopes up to much.)but was still disappointing.
Mine is the LM2
My last attempt on this thing is going to be a ign switched relay, right off the battery.......If that don't fix it........its not a power problem.......at least not on my side of things.
neg side of THE LM2 is attached directly to the battery. Yes cigarette lighter is grounded at the battery!
I took some recording from the race yesterday, but haven't down loaded them yet.
all i know is that every time i look down at the meter after a run......Frozen!!! My tsp was always reading when i looked at the screen.
I will get into that story later, if i find any valuable data..........................
