Regulator

Is it possible to test a regulator to check its working without it being wired to the tractor. I'm currently getting ready to rebuild everything once the paint is on and want to know if to buy a new regulator or risk the old one working.

How about this?

Stefan has a copy of the standard Dexta wiring diagram in the manual on his site should you wish to refer to one.
All the best,

Hi Ross,
All of the guides I have seen, are for tests carried out on working vehicles. The best guide I have found is at
http://www.sterlingbritishmotoringsocie ... _Tests.pdf but all of these tests require a runing vehicle. There is no mention of bench tests of a regulator on it's own. I suspect that you will be left with no choice but to buy a new regulator, but please remember to polarise your generator before you run your tractor. It may be polarised the wrong way around which will destroy both the (regulator / control box) and generator.
Regards, Frank.

A regulator can be tested for functionality with a variable DC supply and a multimeter. But you'll need to connect it to the actual charging circuit if you want to adjust the charging voltage and cut-out voltage correctly.
