Re: Lucas E5H dynamo
Are you sure it's not an E3H?
IIRC the digit is the diameter in inches!

Re: Lucas E5H dynamo
So according to this website the E3H has one large screw in the case holding the pole shoe
Which my dynamo has so must be a E3H
the down side is it's only 45watt

Yes must be E3H
Not sure if this shows more clearly, I think E3H was used on Triumph perhaps othersYou do not have the required permissions to view the files attached to this post.

Re: Lucas E5H dynamo
Hi
According to James Smith's most excellent 'Classic Motorcycle Electrics Manual' the E3H designation indicates an Excentricaly mounted armature, 3 inch diameter body, H voltage control, ball bearing at drive end, bronze bush at commutator end. The book also suggest that the dynamo was fitted to 1938 - 48 Ariels and Scotts.
There's plenty of Lucas information in the archive under technical / electrics:

And also in the Brightspark Magnetos Library:

Re: Lucas E5H dynamo
You will see all bikes E3H fits in the archives 1936-57 ( complete ) Lucas book. The generator section starts with an explanation as to what prefix and suffix letters refer to.
