went to another wallyworld today, and after some heehawing around, they exchanged the battery. checked it before start up and it was 12.28 volts, after choke went off and car at idle, voltmeter reads 12.0 across terminals and at volt gauge inside car ! i then took the altenator off, went to auto zone and had it checked, it passed, readout said 61 amps, but didn't mention the volts. they quoted me $56.99 for a new regulator ! quess i will see if utube has a video on checking an external regulator .
