Tightmopedman9 Posted October 9, 2013 Report Share Posted October 9, 2013 Long story short my radio doesn't work. Sometimes the stereo will turn on, but it is very intermittent. Traced the problem back to the yellow constant hot wire on the harness, it has no voltage. This is not the wire that runs through the fuse box, to my knowledge (the #7 fuse for the radio is red/black and it has voltage). I've been looking for the relevant wiring diagram to trace where this yellow wire goes. Any help with a wiring diagram or specific knowledge would greatly be appreciated!

Tightmopedman9 Posted October 9, 2013 Author Report Share Posted October 9, 2013 It is the yellow/black violet wire btw. EDIT: wrong color Link to comment Share on other sites More sharing options...

Tightmopedman9 Posted October 9, 2013 Author Report Share Posted October 9, 2013 Yeah that's great, I'm assuming I just need to trace 24/13A (I'm assuming under dash gang connector) 11/32 and 2/30. Thanks, I actually just found that same diagram on Matthew's Link to comment Share on other sites More sharing options...
survolvo Posted October 9, 2013 Report Share Posted October 9, 2013 Good deal. Is the radio your only problem, because it looks like it is the ACC power lead, and if your ignition switch is acting up that might be the culprit. I downloaded the whole wiring diagram PDF for 850 and -99 x70 from MVS before they were made to take it down. Let me know if you need anything else. I can copy certain pages, or send the whole thing, but it is a VERY large file. Link to comment Share on other sites More sharing options...
Tightmopedman9 Posted October 9, 2013 Author Report Share Posted October 9, 2013 No, the radio isn't the only problem. Sometimes my flashers/hazards/high beams will stop working, but if I remove the #13 fuse and put it back in they start working again. I seemed to have to fixed that problem with adjusting the contacts in the fuse box, but we'll see. Also, my remote control unlock doesn't work, but that may be a problem with the box its self and has been going on for a while. I was really hoping it was going to be a problem with 2/30, Overload relay X+, so I grabbed the relays off my LPT and tried them, no luck. However, when I was putting back in my old relays after testing the stereo came on for a second, I swapped to my Alpine HU and there was no power again. I guess I need to look at the ignition switch now, ughhh. Link to comment Share on other sites More sharing options...
Tightmopedman9 Posted October 9, 2013 Author Report Share Posted October 9, 2013 I traced the stereo harness to the overload relay under the hood and got about 150Ω of resistance between the stereo wire and the terminal (2/30 pin3 in the diagram). I'm actually not sure if that is the right measurement since this multimeter sucks a ballsack. I feel like any resistance above a few ohms is too much though. Looks like I need to check out 11/32 and 24/13A. Survolvo could you tell me where/what those are? Link to comment Share on other sites More sharing options...

Tightmopedman9 Posted October 10, 2013 Author Report Share Posted October 10, 2013 Re-seating the gang connector fixed the problem. I would be free of so many electrical problems if I hadn't fucked with the wiring when I was 17. Oh well... Link to comment Share on other sites More sharing options...
