Tach problem

[bogies87]

Here is the deal, I switched to the Type II ignition over the weekend and now my aftermarket tach does not work. For the record it worked minutes prior to the conversion. At first I thought no big deal just a poor connection, but after verifying it still does not work. I checked the green plug behind the alternator and have voltage going to it. By the way this is where it's plugged in. My stock tach works and so does the scanmaster...... Any ideas?

its the type 11 module .. just doesnt have enough on the output voltage for another tach

caspers has a vdo tach adapter that should help the signal
