Get yourself one of these - 12V relay tester

i love mine! thank you so much for the donation!!

Where can I get one at

Works, bought mine on Temu for $9.71.

Not sure how reliable these is 🤔 I've use one over the weekend and it tested bad (7 tries).tested the direct battery way all was good with that relay.

I have one but any 5 pin 40a ones fail unless i only hook up 4 wires
