Voltmeter reading at battery terminals should be in the 13.5v to 14v range.....
DO NOT disconnect battery terminals while engine is running since the battery also provides a reference voltage for the charging system to keep the alternator voltage output steady.....how many accessories did you burn out????? (if none, you're lucky)
Have had previous issues w/ Wally World batteries on another vehicle which also had a marginal alternator (two problems at once; almost drove me nuts), get a better battery..
