so all has been perfect. until yesterday i went to crank it and it just made a pop a couple times and all electrical went off. turned off the key and back on and it worked, crank and same thing. voltmeter said 12.6v. so i removed the entire neg bat cable and cleaned all surfaces. problem solved.
so today i noticed at higher speeds the voltage drops all the way down to 11.8v. as soon as i slow way down/let off or stop it goes back up to 14v.

i checked my belt for the hell of it and i have A LOT of play in the tensioner. but why would i really get two issues at once? it still all has to be bat cable related due to the first incident, right?
