That Dyna coil is of a different design, than the pictures I've seen on Motorrad Elektrik website photos .

They have the laminate steel part of the coil, sticks out of each end, and is not covered in epoxy/insulating material .

I've never noticed a main earth connection on my front coil bracket. Maybe a PO moved it some place else. I'll have to check. 
Mine was and now is mounted to the speedo cable fixing bolt the photo is of it before i stripped it down to rebuild.

Lou,

That was one rusty bike before you restored it.

I am talking about the main ground for the wiring harness - NOT the honkin' big ground wire from the negative terminal on the battery to the bike.

Yeh but one of the images shows that "honkin" big wire lashed to the coil where it doesnt belong!!
It wont do the starter motor any good attached to the frame.

My honkin' big ground wire is in the same normal place as yours Lou and I agree I wouldn't put it on the coil bracket if I was to move it. Maybe somewhere close to the starter.

So what are we saying regarding the best mounting point for the main earth cable off the battery? Not on the rear coil bracket? Is it best on the speedo cable bolt as on Lou's photo, or as near as possible to the starter motor?

It should be on the speedo bolt as this earths it direct to the engine block giving the best connection to the starter motor.There is another lighter wire (brown)to the frame ground point
Lower power connections are fine on the frame .

Yes the stock position for main earth from the battery is on the speedo bolt. The reason yours may have been relocated Boo is because some owners move them on account of the speedo bolt being prone to stripping the thread particularly if you follow the pratice of removing the earth regularly to isolate the battery.  

As Lou says somewhere on the engine block is better than the frame if it is to be moved.

Maybe others who have moved that earth cable will chime in and say where they put it.

I have read, but I have not yet made the change, that one of the best locations is the lower transmission fastener on the right-hand side (brake pedal).
This requires a longer cable.

Ken-in-Oklahoma on Boxerworks talks of fastening it to one of the transmission cover screws, with a longer-than-stock screw, and some washers.  On the left-top side (I don't think I've seen a picture).

I take the point about stripping the treads on the speedo mount i always disconnect the earth from the battery end when im working on the beancan or other electric bits.
I wonder if you could  fit the cable to the starter motor mount under the top cover if your going to the trouble of replaceing the cable?

I considered running it through the starter cover, somewhere, but that would make removal of the cover a major pain.

I would think.

I am more than willing to be proven wrong! :)

Ok then...new points gapped at .40mm, new condenser, new plugs gapped at .60mm, new plugs and leads, new Dyna coil with a healthy looking blue/white spark...no start up!! Battery is charged and cranking well.
I'm now thinking about the carbs. Float bowls are at the levels they should be. My next task is to clean the main jets and look for any contamination. Anything else I should be trying? >:(

If its not starting i would be stripping the enrichers at this point, the main jet isnt in use at start.
Theres a good article on the enricher here.
