I have the instructions in front of me, so here goes (It is 12:20 am,
I've been out of school for a week, and I'm still soooo far behind. At
least I got a 4.0 this past semester.....1 more to go).
For the Crane/Allison XR700, for negative ground hookup,
you should hook up the following
RED - PLUS (+) side of distributor
YELLOW - NEGATIVE (-) side of distributor
BLACK - GROUND to chassis
Optical Trigger Cable - connects to trigger unit in distributor
There is a warning block on the page...not knowing what model you have,
I'll repeat it.
Warning XR3000 or standard 12 volt XR700 units cannot be used with
positive ground. Use special XR700 P/N 720-0001 for 12 volt positive
ground. All 6 volt XR700 units are compatible with positive ground.
Refer to positive ground tech note for further information.
Here's a little ASCII art......I can't wait for those little cameras on
top of compueters to become commonplace.......
