This is unlikely you're issue.

Right now, if my battery is low-ish, I seem to have to cycle my kill switch a few times to get my display to come on, and thus be able to start my SPB. I monitor the voltage -- and it seems high enough so I'm not 100% sure why that is happening -- I have not diagnosed it any further -- but I plan to replace the battery (mini-ATV battery) before this race season.

Just a datapoint for you.

Appreciate your input Mike. I will be reinstalling the alternator after verify it's ok. Got the new voltage regulator but before changing it wanted to make sure the current one is bad. I hope it is bad.
