Electrical or Mechanical issue?

[gtzuki750]

Alright so my 1977 750 has been doing great the past couple days riding it back and forth from work. last night as i was riding home from work cruising at about 40mph the bike suddenly dies out and slowly drops in rpms as well as gives a couple loud pops. when that happened the electrical immediately died out, when i got to the side of the road i checked the fuse and it was normal, i checked to see if the lights or dash lights would come on and they were EXTREMELY faint, i also tried to check all my connections to the best of my ability (night time) and everything looked to be connected.

i thought i may have blown something in the engine , so i tryed to give it a kick and i got compression (it felt normal) but it didnt start ( wich is not normal considering for the past 2 weeks prior to this incident, i didnt even have to give it a full kick and it would start up with ease)

im leaning to electrical to be the culprit here, but im really not sure. Please Help GSR guru's

the "suddenly dies out" stuff sounds like you have charging issues and basically battery just couldn't keep ignition system happy, so it crapped out. Of course, you've seen and done the stator tests, right????

How about a teaser...... a quick test
