Car_Commander Posted August 19, 2014 Share Posted August 19, 2014 I have a faulty CAV D5 LA8 dynamo on my Humber LRC. It is running through a CAV Current Voltage Control Box type 141-1 designed for the D5 LA Normal speed dynamo. The replacement that I have available is a CAV DBNB-137 Low speed. Will it work with the control box? Will it damage the control box? Les. Quote Link to comment Share on other sites More sharing options...
fv1609 Posted August 19, 2014 Share Posted August 19, 2014 Les I can't give you a straight answer as I have no experience of them, but this may help you decide. CIS = Cut In Speed V = Ventilated C = Totally enclosed Quote Link to comment Share on other sites More sharing options...
Car_Commander Posted August 19, 2014 Author Share Posted August 19, 2014 Thanks Clive. That's a very useful table. It looks like the DBNB will produce around half the current, start generating at much lower rpm but is only safe up to 4000rpm. The Humber's 4086cc engine max power output is always given at 3400rpm but I am struggling the maximum rpm. Regards, Les. Quote Link to comment Share on other sites More sharing options...
