Hey Grec...any luck with this issue? I am having the same issues.
I bought an IVR3 some time back……worked great for all that time. Years.
But my gauges started acting up this past summer...…sometimes the fuel and temp would work, sometimes not. Always both at the same time. Sounds like your issue.
I assumed it was a bad connection at the limiter. Fished my hand up behind and found when I twisted the connector that feeds the gauges, it would work, let go and it would stop. I figured it was corrosion etc and the dash would need to come apart.... So I let it go til the weather turned to crap.....today....LOL
I pulled the cluster out today to access the Limiter and found that it had what appeared to be a cold solder joint on the terminal that feeds the gauges.
Certainly out of warranty of any sort I figured I would try soldering it.
I did, and lo and behold, upon hooking it up to a battery on the bench (positive to the 12v terminal, negative to the cluster frame), the LED started blinking,…..then after reinstalling the cluster in the car, it worked for 4 cycles of the ignition.
But then on the 5th (not sure why I went for a 5th but glad I did before I reassembled everything), it stopped. Even wiggling the terminal does nothing.
Checked my 12v source in the dash, its fine…battery is charged…..pulled the cluster again to bench test the same as before, and no LED.
The solder joint appears ok. If I had damaged it with solder heat, I wouldnt think it would have worked at ALL.....
So I am at a loss…..any thoughts on what the issue could be? maybe its just toast altogether now?
According to the website where I bought the RTE IVR3 from, RTE was sold to Dashworx which is now shut down as well.
So I may try opening up the unit and see what I can see but aside from that, not many options I guess.
I tried emailing "Greg" from RTE at his old address, but I would guess he wont get that.
I do have an old style one, but not sure it works or not....I guess I can bench test that the same way....but will have to measure the output rather than look for a blinky light I guess...
Any other options as far as the digital style or was RTE *IT*??
