    Welcome to the forum! Do the measurement of the voltage using a known good voltmeter hooked directly to the battery. I presume your current reading is from a fairing voltmeter which is plugged into a different part of the circuit and are usually only a guesstimate.

    You should really be getting more than 13v more like 14v to really have charging. If you're not getting close to 14v at the battery, then there's something wrong with the charging system.
