I found an extremely helpful electrical draw video from Royalty Auto Service. These guys are really helpful. I’ll post The link to their Facebook

That’s the link and it is very helpful in finding parasitic draw whe key is off and out of mustangs, particularly in S197s which is what he shows in this Facebook short video. And he has links to some affordable diagnostic heat imaging that plug into iPhone, very helpful to watch.

Hi joeliravioli,

Welcome to the forums & thanks for posting this link!

FYI, I have ordered the Topdon unit for my IPhone 15 & is on its way. Been intending to pick up a temp gun but this product is FAR more versatile & it records\stores imaging for record keeping which is a BIG plus in my book.

Again, thanks for posting the link!
