RatInDaHat Posted February 16, 2011 Share Posted February 16, 2011 Here is the issue. I am not getting any voltage to the interlock relay on the switch side. The coil side of the relay is good, but the black/yellow wire on the larger plug of the interlock gets nothing(zero volts in reference to ground) when trying to start. From the ignition switch to the connector under the dash is good, and from the interlock relay to the starter is good. The starter is also good. i was planning on just running a new wire from the connector under the dash to the interlock relay. It seems to me that i have an open somewhere on that wire. If that is the case, is this common, or is there a connector or component that i'm not looking at here? Is there anything stupid i'm missing here? Also this is a 94 2wd pathy.

JamesRich Posted February 16, 2011 Share Posted February 16, 2011 Did you check the switch on your clutch pedal? James Link to comment Share on other sites More sharing options...
RatInDaHat Posted February 16, 2011 Author Share Posted February 16, 2011 forgot to mention that i did check the switch and it is working. That was actually one of the first things i checked. Link to comment Share on other sites More sharing options...
RatInDaHat Posted February 16, 2011 Author Share Posted February 16, 2011 (edited) ok i lied. it turns out i am actually not getting a ground at the coil side of the interlock relay. For the time being i have just bypassed the clutch switch by running a wire from one side of the plug to the other side(the side of the plug that plugs into the switch). so it looks like i am not getting the ground to that point, at least that is what it looks like so far. *** New Info *** I added a ground to the ground side of the relay (light green wire) and the truck started right up. Here is where it gets fun. After i killed the truck the starter kept going. So i disconnected the battery, interlock relay and connector 87M/22E(the one by the battery that is between the interlock relay and the starter. If i hook the battery back up the starter turns still. I need to check and see if i have power at the coil connector of the solenoid, but that will happen later. If i don't have power there, does it sound like my solenoid is stuck? Obviously if i do there is a different issue. Starter is a reman from nissan that came in yesterday. Any advice here?

sewebster Posted February 16, 2011 Share Posted February 16, 2011 The solenoid just moves the starter gear into engagement with the flywheel right? Is the switch on the ground or live side? (if it's on the ground then by putting a bypass ground wire you are bypassing the switch entirely and that is why the starter is always running). Obviously most times in life we switch the live side, but, well, cars can be different. Just guessing here... Link to comment Share on other sites More sharing options...
RatInDaHat Posted February 16, 2011 Author Share Posted February 16, 2011 according to the nissan wiring diagrams the switch supplies 12v to the relay which then supplies 12 volts to the solenoid signal wire. Funny part is that right this second it doesn't matter because the starter spins without any of that connected. How i understand the solenoid is that it throws a plunger into the 12v battery contact and the contact to the starter motor. It might also engage the starter with the flywheel. One other thing worth mentioning is that the starter is not engaging the flywheel while it is spinning with the relay disconnected, it is just free spinning.

Ok, well, I could be wrong, but I think I'd call the "solenoid" you are talking about a relay. There is another bigger solenoid that actually moves the gear. Since there are (at least) these two separate components required to actually start the truck this might be adding confusion? Link to comment Share on other sites More sharing options...
RatInDaHat Posted February 17, 2011 Author Share Posted February 17, 2011 nissan calls it the magnetic switch assembly if we want to get technical. It is comprised of the solenoid and switch portion in one. The solenoid part is not engaged, but the switch part is. When it came down to it, my old starter still works, the new starter is screwed, and i got my truck running a few minutes ago. Sucks that it took so much work for an open ground connection, but that is life. Guess i need to get the new starter replaced now. I also learned the merits of a 2wd model for changing the starter. It is literally a 20 minute, or less, job without the front drive components to contend with. -Dustin- Link to comment Share on other sites More sharing options...
sewebster Posted February 17, 2011 Share Posted February 17, 2011 Glad you got it figured out. Super lame that the new one was bad, but I've had this happen to me before too (not with a starter, but bunch of other stuff). Link to comment Share on other sites More sharing options...
