New BDR RT4 Electrical Issues
I took ownership of a new BDR RT4 (#2581) recently and have run into an electrical problem from the very start. For some reason, the cooling fan circuit consistently blows the 30A fuse. I have checked (and replaced) the thermistor (fan switch), the dash-mounted override switch, and the fan circuit relay...no joy. The circuit grounds appear to be good as does the wiring (that I can get to). The car comes up to operating temp very quickly and the fan will initially come on to start cooling. I get the indicator light that the fan is activated. After about 10 - 15 minutes of driving, the temp starts to climb rapidly above 100°C (212°F) to peg the temp gauge. At that point I stop the car and let it cool down. I carry extra 30A fuses and swap it out for the one that has blown.
I am at a complete loss as to why this continues. I'm at the point where BD is sending me a new fan to swap out, but I'm not convinced that will "cure" the problem.
Any help or advice would be greatly appreciated.
Thanks!
Tim
