Heated Visor--First impressions
I've had a lot of trouble in the past with condensation on the inside (and outside) of my visor on a couple different helmets so I bought an electric faceshield and tried it. Today was my first test in fogging conditions.
I formerly used a Schuberth C3Pro, and it even has a pinlock visor , but last spring in 40-degree drizzle I was not able to keep it clear, at all, and in exasperation I went (immediately, in the middle of my ride) and bought a Bell MX-9 MIPs helmet because it had, as an option, a heated face shield (intended primarily for snowmobiles, I think.) The MX-9 is a "dirt bike" type of helmet with a big chin that lets lots of air in. (The Schuberth had, in my opinion, poor ventilation.) I didn't have the heat wired until late this summer, though. The helmet was around $200, the visor was around $100, and I also bought a "Transitions" visor that automatically changes darkness.
Today, the unheated, regular face shield was fogging a bit, not too bad, but I was having to crack the visor open to keep it clear, or even all the way up. Up, down, up, down, etc., etc. It was foggy and 48 degrees, not seriously bad, but I thought it was time to test the heated visor so installed it and plugged it in. Result,
It works well. It keeps the plastic faceshield warm to the touch and actually provides significant radiant warmth to my face. It is, today at least, impossible to fog it up. It will stay on my helmet for the rest of the winter, now.
Electrically, I just spliced some wires together and plugged it directly into the battery charger pigtail that most bikes have for charging. I measured the resistance at around 2 ohms, so about 7 amps, 90 watts. (on a different circuit I have a 6 amp electric garment.) It has an automotive type fuse in the circuit (not sure, it may have come that way, but I cannot remember.) One drawback, is that it uses an RCA plug for the visor power and the RCA plug's outer ring is the "hot" circuit, quite vulnerable and exposed. I'll have to be careful about that, carry some extra fuses. However, the RCA plug does make a nice, secure connection into the visor.
I intentionally tried blowing, huffing and snorting into the visor in an attempt to make it fog, but could not. (The photos were from when I wired it in, not today.)
