If you do not know how to use a multi meter, then using it improperly can ruin the meter. Just wanted to let you know that. Also if you do not how to use the meter you do not need to be splicing lines etc. as you do not know what power you are working with or what circuits are hot. YOu cannot slice a 220 Volt line. Also if your spa is on a 110 Volt line it must be a dedicated line with nothing else on it. You are working with water and electricity...I highly recommend you call an electrician before serious injury occurs.
