69 valiant charging problem

Hi,

I swaped an engine from 73 to 69 Valiant.

I also bought a newer style voltage regulator

And hooked it up, first we forgot to ground the box and bured it, the the altirnator had some problems.

Then we took the old altirnator from the original Slant 6 and but it in, also took the old voltage regulator that looked something like this:

It started charging but after some time (not sure if right away or later because the car was running on battery for 2 weeks) it started to charge at too high voltage (if the car rev's were higher). To the point where the battery was boiling.

After that I orderd a new style voltage regulator (the one I order at the fist time) and it doesn't charge anymore.

Do I have to use the old regulator with the old alternator ?
