MSD distributor/2300 autogage tach

I can't get my 2300 autogage tach to work with my new MSD (hei) distributor (PN8365). Tried connecting it to the tach terminal provided at the distributor but I get nothing. Is there another way to wire it, an adapter, or are there tachs that will work with this distributor? It worked fine with the old points style distributor I had before and was connected to the positive side of the coil. Anyone have an idea or have ran across this problem in the past?

Usually Auto Meter tachs work from tach ports. Do you have to hook up power and ground too?

I suggest you go to Auto Meter's web site, contact their tech support and ask them. Or go to MSD's web and ask them.

Certian tachs need an adapter to work off msd stuff. The tech line can tell you if thats the case here, or if your wiring is missing something.

The 8365 has a low output tachwire coming out of the body and a high output tach connection on the cap. Points style tachs using the digital spark boxes require MSD tach adapters. The tach signal is a square wave signal and has to be changed. I would say, since it doesn't work on the high output signal, it would require the tach adapter.
