Good info, I'm learning. I believe I am interested in finding some suitable general purpose relays. The applications I have in mind will not require much current. One application involves switching on and keeping on the power to the HEI distributor. The relay will be energized by a microprocessor-controlled kill switch circuit. So, the current will be 2 amps and the duty cycle will be continuous while the truck is running. The headlight mod will require about 8 amps and duty cycle will be continuous while the headlights are on. I want to incorporate automatic daytime running lights into my headlight relay mod, so the duty cycle will be continuous while the engine is running and switched on a few seconds after the oil pressure sensor switches.
