What's involved in replacing the stator on a 93 Vulcan 750?

check fuses and condition of battery,it should read about 13 volts or more when engine is at 2000 rpm of the terminals if not replace the rectifier

More than likely it is your reserve lighting device, located on the right side of the battery box. also test battery voltage at rest, then start and recheck with a volt meter.at rest should be at 12 or a bit over, cranked should be at around 13 or 14, rev engine, you should be at 14 or more, had same issue on a 92' ended up being stator was going bad, and rectifier was replaced.

According to information I have found this model uses what is called a Stator to keep the battery charged. If you aren't knowledgeable about Stators, check this video out: http://www.youtube.com/watch?v=MWU2TbEePsY&feature=related

The following is a website that shows a inexpensive repair. http://www.vn750.com/forum/showthread.php?t=16839

main engine heat sing up side have 4 bolt.open it clearance pocket inside.

the oil drain plug is in a recessed pocket at the bottom of the oil pan you need a 17mm socket to remove it

Sounds like u have a open cell in your battery , replace it , you said you had issues charging not lighting or running so this answer is based on the assumption there's voltage coming from stator is this accurate?

yes to remove the stator on the vulcan, the engine must be taken off the frame. BUT.... You can mod it so that you don't have to

The stator comes off with the right front side cover If I recall correctly. All you need is a set of metric wrenches.

Can I get a “very helpful” rating on this answer?

Behind the left engine cover. The engine must be almost completely removed to change it out.
