Here is the picture of the crank trigger for rotaries. The degree wheel on the front of this makes timing a real treat. The wheel can be oriented so that the stock pointer is pointing at 26 degrees (or whatever you want the timing to be) when the reluctor is in front of the pickup for number one housing. This pickup would be on the plug side of the engine. The pickup for the number two housing will be mounted on the exhaust side.
Both leading and trailing plugs will fire at the same time. No distribution of the trailing plugs is required.
No split between leading and trailing is required.
You can use two coils per housing as drawn, or use a double ended coil from a motor cycle. If using MSDs,
use one of their coils.
Timing accuracy is astounding. A timing light looks like a flash light shining on a stopped engine.
Chrysler amplifiers are about $20.00 each. Two required. Chrysler (Dodge Plymouth and others) pickups (from the distributor) are about $5.00 each. Two required Easy hookup. Short wires, Mount the coils beside the plugs. Amplifiers (or MSDs) can be mounted remotely. Wiring diagrams in a Motors Manual at the library.
