[Healeys] Generator now Generating

[Patrick & Caroline Quinn]

Hello

I am pleased to report that the generator of the BN3 is now generating.

First of all I made up a lead with alligator clips on both ends and attached
it to small and larger terminals of the generator. Then loosened off the
fanbelt. Next was another lead from the brown (power) wire on the regulator
to one of the generator terminals. Hey presto the generator spun up thinking
it was an electric motor.

So the generator was working.

On to the regulator with my trusty points file. Everyone should have a
points file. There are two sets of points in the regulator and within a few
minutes of filing it was all done. Actually one had to be adjusted to allow
enough room for the points file and then readjusted back to where it was
before.

Start engine and the ammeter needle swung into the positive and the ignition
light is extinguished. Job done!

Ran the engine up to 200 degrees and now all I have to do is to find out why
there is a pool of oil and water on the garage floor.

Many thanks to everyone who responded.

Hello Patrick

Agree with the recommendations given by Roger and Thomas that you check the
generator prior to the regulator

Another version of the test is:
1. Disconnect the two cables from the generator then link the two terminals
together with a short lead.
2. Start the engine and allow to run at idling speed. Clip one lead from a
voltmeter (set at 20 Volts) to the linked terminals of the generator. Clip
the other lead from the voltmeter to a good earthing (ground) point on the
body (support bracket) of the generator 3. Gradually increase the engine
speed; the voltmeter reading should rise rapidly without fluctuations. Do
not allow the voltmeter reading to reach 20 volts and do not race the engine
in an attempt to obtain a reading. An engine speed of 1000 RPM should not be
exceeded.
4. No reading points to brush gear failure, a reading of 0.5 - 1.0 Volts is
a possible fault in the field winding and 4.0 - 5.0 Volts, a faulty
armature.

Good luck

Norman

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
