So basically my rotor isn't getting the proper voltage to create a magnetic field, and for some reason my negative lead is sending voltage.

Okay, so I checked the stator and it checks out okay. The rectifier is brand new, but I checked it just in case and it passed. Charged the battery up to a full charge (@12.5v). In checking the voltage to the brushes I found that my green lead (negative) is sending @10.55v which doesn't sound right. and the brown (positive) is sending @11.5v. This can't be right.

Thanks, yeah I think I am going to just try to fix the tank. I did check the battery while running and it reads @12.5 at 3000 rpm. Going to try to clean all of the connections to see if that helps. I read that corrosion on the connections can cause resistance, so I will try that today. Also going to check the ground. I have heard that it is a common issue with them. Fingers crossed!!!

Hey guys, I am a new to this forum. I have been racking my brain with this. Here is my dilemma: I just bought a Yamaha Seca xm400j. My problem is 2 fold. I am having an issue finding a new gas tank for it, either used, oem, or aftermarket. The tank has a hole in the right side that the previous owner fixed with JB Weld, and it looks shotty at best. Holds fuel but cosmetically unappealing. I am also having a problem with the charging system. A new battery was installed after sitting all winter, but the bike will not charge the battery. Stator is good, and a new regulator was installed. Anyone else out there have this problem or know of anything else that might help?
