No power to IVR... Reply #15 – January 19, 2010, 06:12:52 PM If it still doesn't work, use the test light to control if it is powered in on/accy. You have base cluster, so connect it between pin 12 and ground. It should glow a bit.PS: 78S05 isn't direct swap part, but it's quite easy to install it into the original IVR body. Quote Selected
No power to IVR... Reply #16 – January 22, 2010, 06:09:52 PM Got the "new" cluster (Thanks 88turbo) and still no go. I did notice that on the drivers side harness, there is a black wire that looks to have a small fusible link on it that looks like it was cut, or broken off. Problem is, I have no idea where the wire goes to. I know the other wires in the harness mostly look like they go to the fuse panel, but I can't find the other end of the black wire. Any ideas?

No power to IVR... Reply #17 – January 22, 2010, 06:30:47 PM Ok, so I checked the pin and wire coloring. Everything seems right except pin number 12, ignition to IVR. According to the coolcats site, my wiring should be light blue/pink. I have a grey wire with yellow lettering that says DO NOT CUT OR SPLICE RESISTOR. I'm imagining that if those wires aren't right, when the key is turned to the on position, there is no power going to the IVR. Quote Selected
No power to IVR... Reply #18 – January 22, 2010, 07:47:41 PM If the IVR isn't working, or if the wire for it was grounding out somewhere, could that possibly cause other electrical problems? The other day when I was cleaning it out, I had the radio on, and smoke started coming out of the front speakers, and then all the speakers started making a crackling/static noise????? Quote Selected
No power to IVR... Reply #19 – January 22, 2010, 09:34:08 PM I tried grounding the black wire out, still nothing happens. I am out of ideas now... Quote Selected
No power to IVR... Reply #20 – January 23, 2010, 06:50:55 AM First, I'm sorry for my mistake, the only mode when it should work is ON mode (not ACCY).There is only one black wire (connected to pin 14) - it's the ground for low fuel lamp. But the wire I was speeking about is black with light green stripe. TC dash has another pin configuration, so it can't be direct swapped. If there is some short it can cause other electrical problems. BTW, light blue wire with pink stripe is probably signal wire to speedometer (pin 16). Quote Selected
No power to IVR... Reply #21 – January 23, 2010, 09:01:30 AM What I am saying is, pin num. 12 in my connector is supposed to a light blue/pink wire, according to this....http://www.coolcats.net/tech/general/8588base.htmlNow on my wiring, I have a grey/yellow wire that says "resistor" and a straight black wire that is either capped off, or a fusible link,coming out of pin 12, however the black wire is not connected to any other wire.

No power to IVR... Reply #22 – January 23, 2010, 09:26:54 AM The black wire is an extra ground wire, don't worry about that.Wiring colors changed throughout the model years and can't be guaranteed to be accurate. I did the best that I could. Regardless of the wiring colors, it's the wiring position in the cluster that's important.Sounds like your feed from the ignition switch might be bad. Or, the switch itself is bad. Has it been changed before? Quote Selected
No power to IVR... Reply #23 – January 23, 2010, 10:58:01 AM I beleive it has. I found a wire coupler with what looks like part number d4ab 14489 that wasn't connected by the battery somewhere. Quote Selected
No power to IVR... Reply #24 – January 23, 2010, 11:22:39 AM I beleive you are right Eric, the wire was in fact capped off, so it was probably an extra ground. I also found, in the engine bay, by the battery, there is a four pin connector where a wire has been cut. It is a black wire with what looks like traces of yellow in it. I'm thinking that cut wire, along with the unconnected coupler, could be part of the problem, however I can't find where either the cut wire, or the coupler go... Quote Selected
No power to IVR... Reply #25 – January 23, 2010, 11:28:27 AM you could use an old wort plug (typical ac to dc converter) like what comes with a chordless phone ect. find an old one that makes 5vdc.or.......an old computer power supply makes 5vdc.inject the voltage you need into the cluster along with a ground and see if the ivr works.repeat process with the cluster installed but god only knows how you can inject 5v in the right spot and have room to do it with the cluster installed.im still looking at diagrams.

No power to IVR... Reply #26 – January 23, 2010, 11:34:57 AM I'm not sure I'm skilled enough to do that......The connector that is disconnected has a part number (d4ab 14489) that seems to be closely related to the grey connector in the cluster harness which has part number d4zb 14489 Quote Selected
No power to IVR... Reply #27 – January 23, 2010, 12:03:25 PM look at page 129 of the evtmsee if you have voltage on the wire coming from the ign sw in "ON" per the below diagram. Quote Selected
No power to IVR... Reply #28 – January 23, 2010, 12:03:46 PM Could the feed from the ignition switch be bad and me still be able to start the car? Quote Selected
No power to IVR... Reply #29 – January 23, 2010, 12:22:05 PM Just tested the feed wire from the ignition switch, the black and green wire is getting power...... Quote Selected
