I used Auto-Meter gauges, tachs, and tach recorders for over 20 years of Drag Boat Racing!
Vibrations? :lol::lol::lol::lol: Hell, our bikes seem like little "trimmers", if even that, compared to those damn boats!
They kept on working like a champ! :2thumbs:
Water Damage? :lol::lol::lol::lol: Mine and many others crap went under & down anytime we crashed or busted a big hole in the boat. And yes they were powered up when they went down!
Dry everything out and again: They kept on working like a champ! :2thumbs:
Auto-Meter is one of the worlds leading manufactures of gauges for race or street. They have "NEVER" made any junk whatsoever that I've ever seen, nor even "heard of" until this forum!
Now I understand that they make our Speedos. But do "they" assemble them or does BDM?...BDM!... BDM also makes the tach board through someone else, then BDM assembles the components that make up the entire "Speedo Unit"!
Fogging? Yea, your right! BDM Speedos sometimes fog! But there is a how-too thread on "how-too fix" that problem I believe.
Now the "Speedo Unit" that Auto-Meter is making, is just like the BDM one and it's just that "A COPY"! VERBAITUM!
If you were going to manufacture a copy of an EHC driven electrical component. Would you change anything on the design of that component, without first "knowing about all the electrical grimlens" within the "BDM electrical system"?
I think "NOT"! and BDM is still working on that very thing themselves!
There are millions of reasons that can cause these things to fail. Are the speedos the "only" electrical component that fail on our BDM bikes?...NO!....Doesn't that tell you guys anything about the "true" cause, or root of the problem?

So please be more open minded as to the "true" cause of these electrical component failure and don't just blame "Auto-Meter" or whom ever.
Just my thoughts here! Good Luck! :2thumbs:
