Never trust continuity always trust voltage drop.(Example)You could have a battery cable that has 100 strands of copper in it and if all the strands were cut except one you would read continuity and think you are ok.WRONG!!!! Try to actually push amperage through it and it won't happen.
Terminal 86 and 87 on an automotive relay are the coil circuit (small wires small amps) = control side
Terminal 87/87a (one normally open / normally closed) and terminal 30 = common .This is the power or contactor side of the relay .(heavy wires heavy amps).So one of the heavy wires will be attached to either 87 or 87a and the other will be attached to 30
You can pull the relay out and put your meter across the female plugs 85 and 86 in connector and turn key or start to check your getting +bv .
Also you can jump 87/87a and 30 while the relay is out with a heavy jumper to turn on circuit this will check that supply wiring is ok.
Sounds like Ricky is leading you on the right track good luck keep us posted.
