Regulator Operation?

Post by PSL184 »

What is the normal operation of the regulator, ie, does it open and close points on a regular basis like the fuel pump or only at a certain voltage and is there a check to see if it is working OK?

The cut-out - does as it says on the box - and cuts IN when the revs rise and OUT when they drop. The other bobbin is the regulator - it vibrates and sends an approximation of a variable signal to the field connection on the dynamo - thus varying the charge rate.

u/s lol

When an alternator is used what is the point of having the regulator can it be removed. If so where do the wires go.

Here's one -<br>Image<br>

Cribbed from this forum - NOT my own work - I DO NOT have any Copyright on this diagram!
The 'new cable' shown in light green can of course be the original small cable that ran from the Ign light to the D terminal on the Regulator. Either extend it - or strip it out of the loom and lead it to the Alt.

It will only develop 60 amps - if you USE 60 amps - which seems unlikely unless you have an array of extra spotlights ? Best idea will be to double up on the original wire that lead to the dynamo large terminal.
