[Healeys] Generator not Generating

[Roger Grace]

Yes agree with Thomas about the replacement regulators; and they can’t be adjusted either that an absolute pain; you can do some malicious bending to set volts that is very time consuming.

Here is another simple quick test procedure to verify generator functionality. You don't even need to start the engine. Remove the armature (big one) and field (small one) wires from the gen. With a clip lead connect the 2 terminals together at the gen. Loosen fan belt (not essential but better practice). With another temp lead connect/flash them to batt supply. I use the solenoid terminal. You will see some sparks and the gen pulley trying to turn if all is OK. It is now running as a shunt motor. If you loosened the belt it will spin smoothly if all is OK.

Hi there,

 

before jumping to the regulator, I suggest that you check the generator output first.

Disconnect the leads from the dynamo. Then  connect a voltmeter from D to ground. Run engine and check if the voltmeter gives you a reading. If no: polarize the dynamo! If you see about 3-6 V: Connect a cable from battery + to the field terminal F momentarily. If you get a 12V reading, rising when you speed up the engine, all is well. Than check the regulator!

My personal view is, that new regulators are a complete piece of junk. Either buy original Lucas NOS or convert your Lucas regulator to electronics. I bought three (!) regulators. No .1 did not work, No.2 did not work. No.3 worked well for two hours and then smoked the brand new armature of my dynamo… With the the electronic regulator I am very happy, no glowing of the charge light at idling speed.

 

Have fun..

Hello

 

Now that the BN3’s engine is running I have discovered that the charging system is not charging.

 

Both the ignition light is staying on and the ammeter while working, stays in the negative.

 

I have checked the wiring and that appears to be correct. As the regulator is NOS, methinks that the generator is not generating. 

 

As far as I know it’s a standard generator as fitted to the early six-cylinder cars. What about new brushes? Any instructions out there for this electrically challenged person? The car is still positive earthed.

 

Many thanks
