My tach falls to zero whenever I "get on it", or really anytime I get above about 3K RPM.
I'm running an MSD 6AL, and I'm aware that there can be tach issues with these. Should I be running their adaptor? In the user's manual, MSD mentions similar malfunctioning on GM vehicles using an in-line filter, and suggests bypassing it. I don't have the schematic in front of me, but I don't recall seeing one mentioned.
Anyone seen this before? What did you do?
Oh, and I'll check the grounds again.
Thanks.
