Technical Voltage regulator question

This may be a dumb question, but I want to mount the voltage regulator on my firewall. This car will not have a hood and I live in Florida---Will there be any issues (short or long-term) if the regulator gets wet?

 

Soldier all wire connections, and use weather tight connectors, and you should be fine.

 

I don't suspect anything major. They normally have a cover and a gasket with 2 screws to keep them pretty
moisture-free inside the cover. On the backside there are some open elements that I have seen corrode slightly
over time even in a covered engine compartment. Bob

 

I’d stay out of salt water rain. I’d say there have been 100,000 to 500,000 hood less hot rods built and run with open generators and even alternators and a million miles in the rain. Many of us look for an overp*** when caught out. Water can not get under a tight ring style connection.
I’d carry a small can of WD-40. It’s the proper use of it. WD = water displacement.
