No power to IVR... January 17, 2010, 12:09:44 PM Like the title says, my gas and water temp gauges aren't working. Of course, I checked the fuses, and they were fine. I made sure the water temp sensor was hooked up, and the sending unit also. I'm not sure what else to check out. The instrument panel lights up fine, the needles just don't move. Quote Selected
No power to IVR... Reply #1 – January 17, 2010, 01:06:58 PM when the IVR is defective,, those two devices go out.first,, unhook your temp sensor wire (little red slip on boot) on the front driver side of intake. stuff that doo dad up onto a ground / bolt or something.turn on key,, your temp guage should peg out. if it doesnt,, in my garage the next thing would be to remove the cluster.page 127 of the evtm.with a steady hand, if you open your ivr up, you may find the little thin wire is broke.I noticed the little copper foil was kind easy to break although i didnt break mine,, i saw where it is a weak link.also check the little contact,, this device is a thermal heat type device where when one leg gets warm,, it bends slightly making the circuit open. if you open up yours and the contacts open (magnifying glass), it may need to be fine adjusting. keep in mind once you fugger with it, any intended calibration on an engineering perspective will be null and void.If something bad happens the little copper wire should burn open. If anyone disagrees, chime in. Quote Selected

No power to IVR... Reply #8 – January 17, 2010, 03:02:29 PM So should I try loosening the small screw? Quote Selected
No power to IVR... Reply #9 – January 17, 2010, 04:06:24 PM is this the standard digital cluster? if so I have one that you can have for next to nothing plus shipping. mine has the collar for the shift indicator in tact and the w2 mod already done. Quote Selected

No power to IVR... Reply #11 – January 17, 2010, 05:21:51 PM Are there any connectors or wires under the hood that may somehow have come undone (other than the little red wire for the coolant temp)? There is a connector in the drivers side fender area with a red wire with a little white stripe and a black wire with a little white stripe that looks like it was connected to something at somepoint...

No power to IVR... Reply #13 – January 17, 2010, 05:57:06 PM Is that like a direct bolt on for the original part? Quote Selected
No power to IVR... Reply #14 – January 18, 2010, 03:03:54 PM Went to the boneyard today, and luckily found another IVR from the same type of cluster, installed it and still not working. I have no way to check it to see if it is good though, so it may have been a bad one too. Is it possible that the electrical film stuff on the back could be damaged? It dosen't look good, and it seems really brittle. Quote Selected
