Need help wiring distributor BB
« on: July 29, 2022, 08:56:36 PM »
I’m moving  from my dyna III ignition back to a points ignition.   My distributor is currently just a housing for the dyna sensor plate (original points plate removed).  I’ll need to buy another distributor or rebuild the one I have. Can anyone advise me how to wire the points  distributor to the coils? I’m running two dyna 5 ohm coils.  Thanks in advance.

Red wire to right cylinder coil, green to left. Wires from "distributor" connect to the - (negative) side of the coil.

Any info as to who has the best points for the T3. Found a lot that were badly aligned and flimsy. Found others that the rubbing blocks wore excessively in 400 miles. I have an original Magneti Marelli set but at 80K miles they are getting a bit thin.

If your main harness under the tank has not been messed with, you'll probably find a red and a green wire with terminals still attached that are connected to the points/condensers wires, as Charlie says above.

The pricier ones from MGcycle held up real well for me. I find it not uncommon for new points to bed in, in the first few hundred miles. After that pretty reliable.

Plus it helps to use a dedicated point grease to lube the cam. I have a 30+ year old tube of Bosch Distributor Grease and it should last me the rest of my days. "A little dab will do ya". Since the Bosch stuff seems to be NLA, Super Lube 2 would be my second choice.

Thanks.  Do I use a blue/black jumper wire between coils?

  If you have a separate power (+) to each coil , then there's no need for a jumper . Peter

Yes, between the + terminals of the coils.
