Ike damaged a portion of my modules and wiring, which of course was salt water. The plant turned them back on, and it shorted the power supply first. If I replace the supply, will it short again on other components? The power supply didn't even get wet, the rest did get wet. Please reply to rausone1 at aol. com

I would expect you to have a major problem with any electronics exposed to salt water. Perhaps a solution might be to rinse all the components with demineralised water then dry them well before powering up. There must be lots of experience in your area.

Good Luck.

I would suspect that the short is somewhere in the part of the system which got wet. There could be multiple shorts. Also, the part which shorted out could be further damaged by the short itself.

Depending on the hardware, you may have to clean the affected components with fresh water and then dry thoroughly, or you may have to replace them. For electronics, I would replace them. For other parts, it may be cheaper (in terms of labour) to replace them than to disassemble and clean them.
