Reply #31 – January 23, 2010, 12:30:51 PM Quote from: 20thanniver-ls;307479If 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?????this is the variable that is gonna bit everyone in the ass. no telling what did this.

No power to IVR... Reply #32 – January 23, 2010, 01:01:01 PM anyone with an 86 evtm?my diagram shows the bk/gn wire going directly to pin 12 feeding the ivr.his case is the following:black/gn wire goes to the fuse box.pin 12 has a grey wire with letters indicating its fuse link but we dont know where it goes.help,, post 86evtm page on this.

No power to IVR... Reply #33 – January 23, 2010, 01:31:53 PM jumper the black / green wire up to pin 12 at the cluster connecter with one of your power seat circuit breakers in line with the jumper.have your coolant temp wire grounded out as well.turn on keyif all goes well, your temp should peg out and fuel should start to read.if all goes bad, your temp and fuel will for a moment start to move but go back to dead.,, also your circuit breaker will have gotten warm and / or your ivr case would have gotten warm.I dont like the idea that your ign wire per the above diagram goes directly to the fuse box. Also your pin 12 wire is gray with a do not splice or cut samped on it. your wiring conflicts my resources so hopefully someone has an 86 layout.to trace out where the gray wire goes will be difficult. I suggest you unhook the battery first.next wire up a 6v battery and inject that voltage into pin 12 at the cluster connector.prob down at the ign switch on A1 and see if that voltage appears there with your test light. Keep in mind that if the resistor is blown open, you will get no power. I would keep chasing that gray wire as far back as possible to finally arrive at where it starts. I hope you get this working.

No power to IVR... Reply #34 – January 23, 2010, 01:35:12 PM Scott, you are the man! Did exactly that, and watched my fuel gauge slowly rise up, and my temp gauge pegged. Now, should I run the black/green wire straight into pin 12, or is there another way to go about doing this? Quote Selected
No power to IVR... Reply #35 – January 23, 2010, 02:12:56 PM hey,, thats your call man.knowing that you have a different layout from what i posted makes me want to not say either way.you did all the work,, i just said what i would do. start off with 1amp. Quote Selected
No power to IVR... Reply #36 – January 23, 2010, 02:40:31 PM Well, maybe I spoke too soon. The temp gauge seems to be working fine, but the gas gauge isn't working now. My speedo isn't lighting up now either......I'm thinking now I may be in over my head Quote Selected
No power to IVR... Reply #37 – January 23, 2010, 05:31:17 PM how many bulbs could you have that are blown?also,, did you use a fuse for the jumper? or did you get confident and not put one in?we really need an 86evtm for this one. maybe you should continue to dig out that gray wire and trace it back.

No power to IVR... Reply #38 – January 23, 2010, 05:38:58 PM when you had the jumper in place, was the lighting on the dash extra bright?if that gray wire was integrated with a resistor somewhere, then its stepping down the current and then the ivr changes the voltage to 5vdc. Quote Selected
No power to IVR... Reply #39 – January 23, 2010, 05:41:11 PM No bulbs blown. Yes I did use a fuse, one of the breakers as you told me. No clue what happened. Even when I hooked everything back up like it was, still no lighting on the speedo. I also noticed that the climate control wasn't working, or at least the blower motor wasn't working anymore. What a mess..... Quote Selected

No power to IVR... Reply #41 – January 23, 2010, 06:25:25 PM Quote from: jcassity;307569look at page 129 of the evtmsee if you have voltage on the wire coming from the ign sw in "ON" per the below diagram.Look at your picture, it's a TC cluster, not base. But in base cluster are the same wires. Cool cats say light blue with pink stripe is 12V for IVR, but EVTM say no, it's black with green stripe. Here is a scan from EVTM - base cluster.But if you have 12V there (on pin 12) there must be some fault in the IVR. Quote Selected
No power to IVR... Reply #42 – January 23, 2010, 06:30:28 PM There is no volts in pin 12, just a resistor wire, and an extra ground.When pulling power from the black/light green wire form the ignition switch using a jumper and inline fuse/breaker ( there is no light blue/pink wire on the switch) and grounding out the little red wire fir the temp gauge - the gas gauge worked and the temp gauge pegged, meaning that the IVR should be good.However, now the radio dosen't work, the speedo dosen't light up,and the blower motor stopped working.

No power to IVR... Reply #43 – January 23, 2010, 09:41:28 PM trinom-here is what he has,,his drivers side pin 12 has a gray wire with yellow lettering that says "do not cut or splice resistor wire".-his pin 12 has no voltage when the key is rotated to on-his pin 12 wire does not go to the ignition switch , it goes somewhere else unknown.-his pin A1 on the ignition switch is black / green and can be traced directly to the fuse box alone on its own terminiation without a piggy back wire, this conflicts the 87 evtm-his car is an 86 tbrid 5.0***his instrument cluster connectors have sufficent slack to allow him easy access to get at. this is odd for most of us since we normally see the harness is attached to the fire wall and is hard to obtain any slack.in short, his setup is different from the manual.

No power to IVR... Reply #44 – January 24, 2010, 11:07:28 AM I have the '86 EVTM, and it doesn't match too. But I think his cluster is standard without any modificatiations.20thanniver-ls, please make a couple of photos of the connectors and the area behind the cluster. Quote Selected
