71 C10 wV8. New Summit HEI dist and ignition box. Tach doesn't work properly, runs negative..or positive but never hits 1000 rpm. Disconnected the wire to the cap, (no inline GM filter) so it does not burn up. Obviously I would like to have the dang thing functioning properly.
Thoughts and recommendations....
I have never run a ignition box so I can't really help you out. Only thing I can suggest is call summit and ask them about it.
This last tach I just installed in my 67 ramp truck I did use a 5amp fuse on the hot wire going to the fuse block though. No filter going to the coil though.

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
