I am looking to replace the Dizzy in my Bug with a replacement unit with Electronic ignition already built in.
At the moment though I have a ballasted coil on my Bug (Running standard points)
Would I need to replace this with a new non Ballasted coil or will the new unit work OK with the Ballasted Coil...?
Would there be any issues in replacing a Ballasted Coil with a Non Ballasted...?
In days of yore before electronics had been discovered, the function of the ballast resistor was to reduce the voltage supplied to the ignition coil primary coil to 9V. At 9V supply, the (ballasted, 2 input connections) coil delivered a secondary voltage to the points and thence to the spark plugs sufficient to run the engine under normal (ie running temperature) conditions. But what about COLD conditions - as at start-up? Enter the ignition switch. In starting, this fed 12v to the coil primary BYPASSING the ballast resistor, and hence delivering around 1/3 more voltage to the primary. This then generated around 1/3 higher voltage in the secondary coil, thus delivering a 1/3 higher voltage to the spark plugs, to facilitate cold starting.
In a modern electronic ignition, the circuitry in the ignition module takes care of this function, and indeed generally offers a more complex voltage and timing profile according to what it sees the engine doing in terms of rpm and trend (eg cold start, rpm rising, rpm slowing etc) so the ballast resistor can be consigned to the museum, along with the points, condenser and all their mechancal problems.

Little-John: I watched Mike and Eddd. restore a Bond Bug on "Wheeler Dealers." At the Woburn 40th birthday party there were two very professional looking 4 wheel Bond Bugs (one yellow, one green.) Were they factory versions? How were they done? By whom?

mybug: Anyone know the whereabouts of PTO 365M? It was mine back in the early 80s and some pix have surfaced here (apparently from ebay around 5 years ago) so is it still around?

karl: Andrea, just seen your post. if you're still looking try putting it in the for sale wants thread.

mybug: Searched and spooled through every image/video/old ad I can find on the internet, I'm thinking that PTO 365M is not around any more. May be resting in a shed, but given the small and tight-knit Bug community, I'd have thought that someone would know it.

crabo: Does anyone have the registration plate numbers or the chassis numbers for the Rothmans Bugs (six of). I friend of mine has just purchased a white Bug (700E) in need of restoration, reg URC 42L, chassis no BR62313, eng no 9816.

jefferdp: All, does anyone know the size of the headlights on the bug, Some say there 7/6" but that seems a little large to me. Also where can you get replacments now?
