Do dyna coils earh on frame from mounting bolts?

don,t think so,there,s two terminals on one side of the coil for pos and neg connections, the experts wil be along soon to correct me if i,m wrong :wink:

Looking at the clymer manual they ground through the points,but i have always made sure where the coil bolts are i get a good contact.

No 'additional' ground required Brian.

Make sure that you use plastic or nylon spacers between the coils and the frame, as the terminals are so close power can easily arc across and cause a dead Zed.!

Better off using brass spacers and heatshrink around them. Brass conducts the core heat away better.

Bit confused on this thread i assumed the coils were earthed through the mounting bolts to the frame but i was going to run an extra ground wire to the frame anyway,some replies on this thread say to put insulators between the coils and the frame?.....!!!!!!!

the insulators are to prevent a short circuit between the frame and coil terminal.the mouting bolts will take the heat away ,as well any "eddy currents" (they cause heat by the way !)

Here's how I mounted & insulated my coils.

Oddly enough Mikey was getting all sorts of electric shocks on his Zed, until he removed a bit of powdercoating & earthed his coils directly to the frame, although that could have been because the wired earth was a bad one. :shock:

See what you mean bear, that bottom terminal is very close to the mounting bolt will put some sleeving to stop shorting of low tension terminal to frame do you think its a good idea to run an extra ground wire from the coil metal core to the frame and not just rely on the mounting bolts?

If your wiring is sound, then you shouldn't need to, but it certainly won't do you any harm.
