Relay question

Checking all the relays available, I used an Ohm meter and found continuity between posts87 center and 30, and also between posts 86 and 85. So following the headlight wiring schematic, when the headlight relay is primarily energized by the starter relay, it puts power at one high beam or low beam, whichever is plugged into that tab, because of the two #87's. posts 86 and 85 being respectively ground and hi/lo switch is easier understood for me. Can anyone explain why the 30 and 87 are connected and not the two 87's as stated in a separate topic tonight. The two 87's actually are two separate circuits that can switched between for hi or low or combined to work simultaneously.

you're talking about 87 and 87A, right?
They are the same circuit. I dont recall what I did with the wire on my pigtails that goes to that connection. (the pigtail had a smaller guage wire on the 87A)
The relays cannot be switched to different circuits. Maybe some fancier ones can, but not these.
30 should be the power in wire.
30 and 87/a shouldnt be connecteted without signal. I bet if you were to cut the thing open, you'd find a burned up mess.

not to be difficult, but relays are essentially switches, activated by switches. pole #85 switches between 87 and 87a via the dimmer switch. I will cut one open and let you know what I find. thanks for the input.
