Aurora HV70M High Performance Ignition Installation Instructions
The HV70M may be mounted in any position (vertical, horizontal etc.). It is however recommended that a location be chosen with free airflow away from direct sources of high heat, such above exhaust manifolds or directly mounted on the engine itself. The supplied 36” high efficiency coil lead allows for remote mounting away from hot and moving engine parts. The coil lead may be shortened after installation should it be required. As well, longer coil leads, up to 72”, are available from your Aurora dealer to aid in difficult installations. Some consideration should be given to the routing of the coil lead in relation to distributor and HV70M mounting location. The coil lead must avoid moving engine parts, or surfaces that could cause abrasion. It is also strongly recommended that the coil lead avoid being bundled with any other wiring harnesses.
Suggested mounting locations are inner fenders or firewalls for pickup trucks and cars. Vans may find locations on firewalls or on the underside of the hood cowling (below windshield). Class “A” style motor homes can accommodate the unit out front on the cowling above the radiator support. Some G.M. powered chassis may find locations behind the distributor on the inside of the floor transition step of the engine cover. Care should be exercised that any under hood locations do not interfere with hood hinge operation or proper hood closure.
The supplied mounting screws are self-drilling and therefore can be driven directly with a #2 Phillips driver bit and a drill. As an option, a 1/8” pilot hole may be drilled and the screws installed with a #2 Phillips screwdriver.
