Stands alone alright

By   on  Verified Purchaser

It seems to work right (I've got bugs in a different part yet) but yeah, it's running fine through the ignition part and I'll buy another one when I need it.

Works great, very simple to install, even has an extra wire for tach. The way you program is old school, like me. Installed on fxdfse after it was in a fire. Went with this and mikuni carb. Simple and reliable.

is a voltage regulator required? and how's b. the battery kept. charged?????/

This product only controls the ignition system for Harley Davidson Twin Cams. Your bike would still require a charging system to keep this unit up and running.
