I have a 2001 L47 V8 Aurora and I want to modify it for diagnostic purposes to that both radiator cooling fans turn on at high speed with the ignition. From what I understand the configuration uses multiple relays to run the fans at slow speed in a series circuit or high speed in a parallel circuit, if this is correct. I would like to jumper one or more relays so the fans run continuous at high speed, again, for testing purposes. I would like to drive it like this for awhile an monitor operating temperature.
Has anyone performed this modification? Which relays should be jumped?
I realize that pulling the temp sensor causes the fans to run, however, the inability to monitor temperature from the dash is undesirable. The temperature must continue to be read by the computer while the fans run constant.
