VT1100 C-another charging issue
Battery died and left me stranded last week. Recharged battery and checked voltage while grinding starter and voltage did not drop below 11.0V so i think battery is OK. Checked voltage at battery while bike is running and have 14.1 at idle, drops to 12+/- while holding steady at about 3500 rpm then suddenly drops to about 6-9 V after about 30 seconds at higher rpm. Is regulator engaging and reducing voltage to battery because it us fully charged, or do I have some other problem?
I will be checking the yellow wires under the seat for burned or corroded connections that I have seen on this forum, but I am concerned about the voltages at the battery at 3500 rpm. I think they should be higher.
I have also been reading about upgrading the regulator/rectifier to an aftermarket MOSFET unit. Any thoughts about this is also appreciated.
