Thanks, guys. Primary ohms resistance is .7 on msd coil and .6 on "recommended" Mallory coil, so I don't think that is the issue. Will check cap as suggested and try another set of wires also. Tach worked fine with MSD last week. Is the Mallory that much more "powerful" than the MSD? Also, per Mallory instructions "do not ground to engine block, ground to frame or chassis". MSD says ground to negative terminal of battery or engine block. Thanks, Ron.
