I have an optima yellow top that never seemed to get charged properly
from the alternator.   About a year ago I added a supplemental solar
panel (el-cheapo brand):

Any idea if this charge controller is putting out enough voltage?  The
manual
   http://www.sunforceproducts.com/prodinfo/manuals/SunforceSolarManEng.pdf
suggests it will charge up to 14.2 volts, and cut back in at 13
volts.   Problem solved ?
