Jabiru uses Kubota regulators, type Kubota RP201-53710
On the Jabiru engines, a common issue is the connection from the coil to
the regulator and from the regulator to the battery and ground. The
spaces in the Kubota regulator are underrated for the application.
Advice is usually to cut off the original and use good quality spade
connectors.
