Blowing voltage regulators

What part(s) 'blew'?

Only the regulator, first time alternator of natural causes.

When you talk electro mechanical are you talking original style where there are coils that make and brake a connection to the field?

This is the points type regulator

Wiring is old! That said, think about it.

If all is to snuff these issues are rare. I run and electronic unit and single field Alternator that looks just like the old mechanical. All new wiring and no issues since 2014! Most of these issues are related to old tired wiring! It may look OK until you strip back the insulation and find lots of green and black!

What harness did you use? Is there any premade kit that is plug and play or did you use an universal kit?

Going to go tinker with it as I got the new regulator, read somewhere about adding an additional ground wire to it, so I will try that and put an wire between the regulator and the engine block/firewall ground.
