Hoop thanks as I forgot to look for mine.. There is a typo in these under number 2 on these instructions it should say if the light goes "out", not on.
Personally if you have never used a KRW fixture (glad hoop asked), then you'd be best learning with a V-8.
Honestly attempting to do a V-12 on the KRW fixture is very time consuming, and a bit more confusing than on a machine. I tried to do one on my KRW once and decided it took way too long, and I never could get the seperation exactly right.
I wish I had someone here to hold a video camera as I have a V-12 to do tommorow.
The KRW instructions do not make it clear as to what your objective is. You are essentially building and setting up two seperate 6 cylinder distributors and then syncing them 22.5 degrees apart. Syncing them is very important and it seems most skip that step.
