If you're using a 3-ohm coil from Pertronix, the BR is not required. If you're using the 1.5ohm coil, the BR is required. If the BR is not used, the 1.5 ohm coil may over heat and/or damage the Pertronix unit.

However, having run both setups, I can say that the 1.5ohm coil with stock BR runs better than the 3-ohm.

Stock BRs can be found at MSA, on Ebay or (I think) at nissanparts.cc

I check for the connection and the cable are connected the Gw an BW

I run it with and without this connection but i don't get any spark,

Do you Have GOOD Clean ground ?

It took two weeks for me to find Poor ground. :stupid:

Engine block -- Body-- Alternator--even ran ground to intake manifold and small ground wire from block to distributor base at timing adjust tab bolt.

(Easy to test with alligator clip test leads)

Tuck \o/

I don't know about all of that. My cars run fine without running extra ground wires. If you have to do that, then something else is wrong.

Tank you all, i am goinig to check for the grounds,
