These relays (in Junction Block #3) will get warm during operation since they are always active while car is running or even just with the switch to ON. I’m wondering just how warm should or can they get? They’re not to the point of hot to the touch where I can’t keep a finger pressed to them (almost though) but they are extremely warm, low end of hot. How much is too much? Rather arbitrary, I know, but still curious.

This is a follow-up to the starting issues I was having when outside air is cool.

Swapped these, along with a few other items, and she’s running. Just wondering if there is a deeper, underlying problem causing the relays to overheat.

Hot in the shade.
