Problem with tach and MSD ignition 2F (1 Viewer)

[85roktoy]

Installed a Bosch tach this morning. Everything is hooked up per the instructions with the green wire going to the negative side of the coil. It’s been upgraded to the MSD electronic ignition. Tach comes on and jumps to 0 when I start it but RPM’s aren’t registering. Any ideas? 2F stock motor except for the electronic ignition.

need an autometer tach or a tach adapter for the bosch to see the msd......common thing with msd.

Disregard. MSD box has output wire for tach. Thanks!

What MSD parts did you order? I’m looking to make switch.
Thanks

Sorry I’m unsure I bought it this way. I think it’s the 6a model.

Ah, no problem. Is it the stock distributor?

I believe so.
