Tested a few voltages meters and they were all the same.
I then tried a correct rebuild old style regulator and the voltage dropped to 14.1 and then after running for a few min it settled down to 13.7-13.9v.
Are there any disadvantages using a old style vs new style regulator. The new style I have is an expensive USA 519 The old style is date correct and would rather use it if they work good.
