Do the V3 boards include the tach output circuit for using Smiths etc. tachos or do I have to build that as a sepatare unit?
Looking at the schematic, I notice the transistor circuit between the tach out and the saw pins... is this the tacho circuit now "built in"?
As yet, I havn't built my MJLJ (not even ordered the bits yet), but want to make sure before I do order the components.
Cheers

Yes, it provides a 12V tach
Yes, it provides a 12V tach output signal. See the <a href="http://picasso.org/mjlj/?q=node/606">Vehicle Installation</a> page for more info.

Thanks Brent
Wasn't 100% sure if I needed to do the diode circuit. I have tested my spare tacho on a 12V sq wave @ 33.33hz and the tach says 1000 which is correct (4 cyl 4 stroke). I'll be hopefully building a MJLJ very soon.
