Hi again

When you day there is a short, how did you measure it? - resistance to earth? It cannot be a true short to earth as it goes to +12v when the ign is switched on?

I have not come across an 8910/20 that has failed thus far, but have a few tachos. Additionally, I have had several 6ALs where they operate ok but their tach outputs do not... Just a thought..

Do you have access to a scope?
