Reply to "Replacement of a fuse in an MTH TIU?"

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!
