If you have a multimeter you can check the regulator and see if its working proprly. Pull the wire off the temp sensor in the therm housing and measure the voltage on this wire to a good ground. You should get 7V, if not check the ground for it. If the grounds look good, measure the voltage on the green ground for the reg, and if it is any higher than 0 then the reg is probabaly dieing.
There is a lot of info on this forum on how to make one, if not someone may have one they can sell you. Unfortunatly, Marshall passed away a little while ago which has saddened many as he was a great guy.
