Headlight relays - back EMF diode required?
Sorry to talk techie but...
I finally wired in my headlight relays today. I didn't use the Eastern Beaver setup because my setup (dash, DRL, spots, aux powerlet, USB chargers, voltmeter, battery tether switch, separate fuses for each headlight/beam) is a little complicated so I put it all onto a PCB mounted in a little sealed box under the front side cowling.
But, I notice a very small flash in both indicators (on the instrument panel) when I switch between hi and lo beam. My relays switch off and on when toggling between beams.
I'm a teensy bit worried I should have put diodes back across the relays to dissipate the back EMF when the relay coil collapses. Does anyone know if the Eastern Beaver relays, or other, use diodes for that purpose?
