If you need help repairing TIU just let me know ! be glad to help you! chances are if you blew a fuse and its still doesn't work might also might need a TVS diode replaced in one or more channels ! usually if you have had a track short engine short or derailment the voltage spikes that are created will blow the TVS diode for a dead SHORT ! any time you have a spike even if your house powers voltage spike can damage your TVS diodes, I have even had a customer have a Tvs diode shorted because of the surge during the summer when his air conditioner compressor started up caused a voltage dip causing a voltage SPIKE AND DAMAGED his tiu THE SAME SPIKE can also blow an Engine Board!

I have had numerous issues with derailments etc. so your scenario is more than logical.

Under normal circumstances I would probably just pick up a new TIU but with their availability in question and the prices they a commanding on eBay I am going to have to make due.
