Van gauge issues?
Mel said:
I've noticed quite a few posts of people having problems with Van's gauges. When I flew the factory -9, I noticed that the manifold pressure gauge was somewhat slow to react. Right now I am working on a -6 that had a runaway alternate. The only "Van's" gauges in the airplane are the fuel gauges and they were the only gauges in the airplane to fail. Is this a coincidence?
Mel I have made the same observation. The last time I said anything I got a surprise personal e-mail from a Van employee that my comments where irresponsible, when I implied that there was design or possibly quality issues.
I'll just say they are a "VALUE" product that does what Van says, and Van's supports their product. Which I do believe. However I know that both Van's ammeter and MAP gauges seem subject to radio frequency interference (RFI). Typical complaint is they "Peg" when you key the Comm radio mic. I also know that "Van" said this is OK when they where notified. I helped solve one of these problems and it involved moving wires, twisting wire pairs.
Again if you have a problem contact Van and let them solve it. I personally have a GRT EIS 4000 which I am satisfied. My Van gauge experience is thru a friend and another Gent I corresponded with, who I helped solve another Van gauge problem, I mean issue.
I have read the other problems from a few others. So to be responsible I am aware of a handful of issues and most have to deal with the RFI issue. There was also a few Van gauges that died, but I don't have personal knowledge of those.
I have not heard of a slow reacting MAP I have heard of one person complaining about their oil pressure slow to react. Van's position on their product is they support it and they are not aware of any overall consistent problem, and all issues are unique, case by case. My opinion is their MAP and Amp gauges are prone to RFI in some installations.
I think Van's (ISS) gauges are way better than Westach. I used Westach on my first RV and was not impressed. For them money they are inexpensive, so what do you expect. When people charge 10 times or more for a gauge, they are a deal, but I also think you get what you pay for.
