General wiring question

[Matt Colie]

Corey,

Both of the above answers are correct, but what both are assuming is that you have changed the points out for a Pertronix 1181LS. If you have not, I
highly recommend this mod. Even when you have, there can still be issues if leave the ignition powered up with the engine still. That is true both
with the points and the Pertronix.

As an add on to Matt's post, it should be noted that there are two versions of the Pertronix ignition modification that will work in our points type
distributors There is the 1181 and the 1181LS. Last summer, while doing some work on the FI that I have, it suddenly refused to start. After some
diagnosis, finally found it had no spark. The 1181 has a pick-up and a ring of 8 magnets that go under the rotor. One magnet dislodged and in turn
scrubbed the electronic eye until I had a total ignition failure--complete with coil boiled out. Apparently Pertronix had problems with the 1181
magnet ring, and the upgrade is the 1181LS (LS is for Lobe Sensing), which does not have Magnet ring. The hope is that you have the "LS" version.

Yes, what I have is the 1181LS. No magnetic ring. In fact on applied's site, it says "won't burn up if ignition is left on with engine off", which
gave me confidence. Now considering all of this, do I need the resistance wire (consider my comment above about it already being spliced in two
places)? I get 6.6 volts to the coil with ignition on, engine off, about 9 v during cranking, then 12.5 when engine is running. Interesting
