Hello all, it has been 7 months since my last confession**Seriously though, I had modded the XJ, worked out the bugs and she's been one of the most reliable vehicles I have ever owned. My question is this, what is the purpose of the orange diode that sits on the driver side behind the head light near the fender wall? The engine runs great, I just happened to notice that the auxiliary fan hasn't ran yet this summer! I ran power from the battery to check its operation, it runs great. The temperature switch that screws into the radiator is open line all the time, even after driving for 30 minutes in 90 weather. I just installed the switch befroe summer, it could be bad. I'm wondering what role the diode plays in all this? I removed the diode and connected the 3 wires directly to each other and the auxillary fans runs whenever the ignition is turned on, engine running or not. AC running or not. I already have a toggle switch ran to that corner but I personally prefer to let the switches and relays do their job, If anyone out there can tel me the ins and out on this diode I would appreciate it.
