Qestion!!

I was installing an MSD 6A box, and was following the directions for wiring an MSD pro billet Dist,since that is what i will be using. Ok got it all wired and ran the original tach wire to the tach input on the 6A box. Read further on in the instructions and it mentioned a run on problem that might happen.
Has anybody experienced this probelm using the factory tach, and if so how do i fix it? and do i need to leave the capacitor in line that ran to the original dist?
Just thinking ahead in case i have a problem. Thanks in advance for your help.

Kevin-- RTFM!!:rolling:

The run-on with an MSD box is from the alternator backfeeding the MSD box and keeping it powered. They give you a diode to stop that from happening. I didn't have any problem with my Summit/Mallory box. And they also said it doesn't happen on all cars. If you'd just do the simple thing and swap to a mechanical tach you wouldn't have to worry..:D


:cheers:
