#5224, "RE: need help with megasquirt relay getting hot" In response to In response to 14
Sure, you could definitely do that. You'll need to start looking at everything that's connected to that relay. As far as I can tell, that includes the fuel pump, anything connected to the FIDLE line, the fuel injectors and the MegaSquirt ECU itself. You'll also want to check J1 and make sure it's configured right for whatever device is connected to the FIDLE relay.
