Can I remove my Sprinter's Siemens VDO Tachometer, which is dead after it drained the battery? Now odometer and speedometer not working.

Hi. I've had this bus for a couple of years. It's a plaxton conversion on a 2004 413 CDI.

The tacho has always drained the battery, it takes about 3 weeks of standing. This time it was standing for a lot longer and the tacho RAM memory must have drained too. I now have no instruments working. I've taken the tacho out and unplugged it, but the circuit still causes a parasitic drain, I assume this is because the circuit still forces the dashboard odometer and clock to be powered up.

I would really like to remove it and have the dash working as normal. I'ver done some googling about how this can be done, but I admit to being a bit confused on this one! Does anyone know whether this would just need remapping, or are there other steps involved - such as re-routing the wiring?

Many thanks in advance.

The wiring for that is different, you would do better to keep it as it is and just fit an isolation switch. Also be aware that depending on what your using the vehicle for it may legally need a tacho.
