Got a mate with an 100 series with a 1HZ engine and after fitting a new internally regulated Denso alternator the dash lights won't go out.

Dash lights not going out on start up suggests the alt isn’t providing enough juice to the battery. (It’s normal the dash lights to stay on for a few seconds until the battery recovers).
I would double check the new install - something is amiss.

Alternator charging OK. I am thinking a problem with the charge light relay circuit.
I deleted my comment because it wasn’t relevant… in the end. I had misread the issue. Sorry
Not sure what you mean re charge light relay circuit. But that would just be one light, not all the dash lights, no?
There are 2 kinds of regulators for these things. So when I had mine rebuilt I had to swap the regulator. I have an old post somewhere here about it.

My apologies, it is an internally regulated alternator. I will edit the post.
The alternator regulators I did share are both internal regulators. Basically one type is ecu/computer controlled. And the other one is not.

Problem solved. Dash lights caused by a faulty ABS module.
