Just finished headlamp relay circuit (built self) this is a 2 headlamp system, 76 corvette (has no high beam lights connected to headlamp circuit).
When turned on lights - both headlamps blew. (h4 80/100 watt).
Circuit is:
orig headlamp wires one side only: (high/low) to coils of 2 "bosch" style 5 wire 30amp relays - n/c terminals not used.
grounds all are to chassis: 2/14ga from lights - 2/14ga from relay coils.
power in: from "batt" connection on alternator thru 30 amp fuse. 12ga. approx 2ft long. to both n/o terminals on relays.
power out: to headlamps from n/o on relays: 2/14ga for high / 2/14ga for low.
all connections made with crimp connectors, heat shrink & dilectric grease, except terminal to alternator which is both crimped & soldered.
Never blew headlamps before, replaced for relief to h/l switch, and additional voltage to headlamps.
Have I done something wrong ???
Help please !
Had been thinking about similar circuit for HEI ... now afraid to do due to above - presently power in at distributer is 0.5 volts less than battery ... is it even worth doing ?
Thanks !!
