Weeks of humidity (92% maximum that I've measured in July) have also highlighted another important issue: corrosion.
The horn stopped working and became intermittent. The wipers also refused to move, inching forward to suggest the motor was basically stalled out. Unfortunately, the wiper linkage, arm, and motor are all behind the dashboard.
After much sandpapering and cleaning the electrical contacts on a completely disassembled steering wheel, the horn is functional again.
The nut that tied the wiper linkage together on the passenger side underneath the windshield was extremely tough to get off, and heavy rust had built up on the entire metal assembly. The threads had galled on the bolt.
The entire thing was WD-40-ed and sandpaper-ed up and another bolt was found that actually fit over the threads. I didn't have threadlocker on me at that moment, unfortunately, so we used general purpose silicone grease instead.
I'm considering putting some copper anti-sieze / dielectric grease on the contact strips that've been sanded to expose fresh, un-oxidized metal. I found a little inexpensive tub of "copper conductive grease."
I could also use it on the battery terminals, chassis grounds, etc. Perhaps to mount the ignition coil, improve heat exchange between its metal base plate and the rest of the chassis.
Also going to replace all the exterior bulbs with LEDs, and the flasher relay with a digital one with an adjustable time pot. I don't like seeing the almost 1V drop on the voltmeter, when I'm indicating, every time the incandescent bulbs turn on.
Another thing I'm considering is removing the blower motor pack (or just disconnecting it and leaving it in the airstream as is) and installing a PWM knob to control the cabin blower motor. Don't want to waste any watts - I haven't got many to work with.
