Interlock Module: Notes

A heavy duty GREEN colored module and a light duty YELLOW module are used. Differences in modules are the ability for one to carry more load current than the other, and heavy duty module has an extra terminal connector. Both units use identical 14-way connectors. The heavy duty module is used with solenoid-actuator starter, when installed without a starter relay in the Lincoln and light-duty unit is used in all other applications. The two modules are not interchangeable.
