make sure that you have a fuse as close to the battery as possible. check everything with a volt meter and not a test light, ever. try running the relay of of a switch for a while, though I don't see a reason since a relay can flip with very minimal voltage though I could see where the can bus flicker could cause this and the need to add a capacitor just like the headlight upgrade fix for hid conversions. bad relays are rare but they happen, I would double check all of your connections and make sure nothing came loose that would raise the resistance values and cause the relay to over heat. check as posted for proper sizing of the wires and relay, may want to think about adding a second relay if you can't find one large enough.
keep in mind the more amps through the relay the more it will arc and will cause the relay to either stick latched or burn up. this was the case in a lot of starter kill relays back in the day.
