Cocacolakid,

Are you driving these relays with your PIC? If so how?

I guess what I am asking is: Are you sure that the noise isn't coming from the coil of the relay? Can you hook a relay up to your pic without a load and fire it and scope the noise?

You see I have never managed to induce enough noise from the AC mains side of a power supply thru to the DC side to reset a PIC...but I have done it by driving inductive loads thru improperly filtered drivers with my PIC.

Again, perhaps I am not understanding your problem, could you please show us a schematic?

Regards,

Joe.
