Battery overcharging.

[Tony Press]

And I. The dynamo is a C35 which have the field resistor in the base of a of a CFR2 cut out  while earlier C35 dynamos had the field resistor in the box on the dynamo connected to a CF3 cut out. This car has the later C35 dynamo connected to what appears to be a CAV type E cutout which doesn't have a field resistor. So the options are find and fit a CFR2 cutout or a simpler solution is to fit a resistor between the dynamo terminals.

So that is why the two terminals are connected giving full charge ate all times which is OK with the present set up.

As noted the third brush must be reset to reduce to reduce the Dynamo charge but as I said if the battery is overcharging at this setting then turn on the headlights- simple.

There - exhausted my electrical knowledge
