BoneheadJeeper Posted February 21, 2020 Share Posted February 21, 2020 Ive been tinkering on this guy for a bit, you all helped me find the no idle issue and I really appreciate it, so thank you. But...now i have new issues. I was driving it today on the longest trip since purchased, and the trip was mostly down the road and back. Its now, after getting towed, in my yard without any electrical functions... Turn the key and nothing, but i have power to my fuse panel under the dash. I have a new battery, terminals are fine. I turn the key on and the radio doesnt even get power. It also started a horrible miss right before it completely shut off. Ive checked voltage on ignition with key on and it has 12v along with battery. Any help would be greatly appreciated. Link to comment Share on other sites More sharing options...
eaglescout526 Posted February 21, 2020 Share Posted February 21, 2020 Check the starter solenoid under the relay center on the passenger side fender. Check for corrosion and such. Check the CPS too for the proper AC voltage. Link to comment Share on other sites More sharing options...
BoneheadJeeper Posted February 21, 2020 Author Share Posted February 21, 2020 It died out as I was driving, would the either of these cause it to be dead in the water, no radio power or anything? Or cause it to spit and sputter randomly? I just replaced it with a new one when I purchased it. I swapped out relays and no change, haven't checked cps yet, what should the proper voltage be?

jdog Posted February 21, 2020 Share Posted February 21, 2020 Check the fuse able links near the battery, they look like normal wires but will open like a fuseStock 1988 swb 4.0 ax15 np 231. Link to comment Share on other sites More sharing options...
Ωhm Posted February 21, 2020 Share Posted February 21, 2020 Using a voltmeter or testlight check for B+ on the following pins: D1_5: B+ (Hot at all times) D1_2: B+ (Hot during KEY ON/CRANKING). D1_6: KEY ON (B+ (For 2-3 seconds)) or CRANKING (B+ (Hot during CRANK)). Link to comment Share on other sites More sharing options...

54bobby Posted February 21, 2020 Share Posted February 21, 2020 under hood, pass side under relay cover. should have yellow caps over them Link to comment Share on other sites More sharing options...
Ωhm Posted February 21, 2020 Share Posted February 21, 2020 Could have YELLOW boot caps on them. Link to comment Share on other sites More sharing options...
BoneheadJeeper Posted February 22, 2020 Author Share Posted February 22, 2020 So D1-5 is hot. The the others are nothing. Also checked fusable link, ive never mesed with these before so i just stuck my volt meter + tip into the rubber, i got 12v. Link to comment Share on other sites More sharing options...

Pay close attention to the green ones (open, burnt, etc). If Fusible Links look good. disconnect C268 at the IGN SW. With a testlight or voltmeter check C268_B3 for B+ (Hot at all times).

BoneheadJeeper Posted February 22, 2020 Author Share Posted February 22, 2020 I have nothing at b3 Link to comment Share on other sites More sharing options...
Ωhm Posted February 22, 2020 Share Posted February 22, 2020 Open circuit/fusible link between IGN SW (C268_B3) and Starter Relay (Fusible Link F). Link to comment Share on other sites More sharing options...
BoneheadJeeper Posted February 22, 2020 Author Share Posted February 22, 2020 Ok so ive checked ohms, voltage checked all fusable links, everything but the b3 terminal is getting the correct amount of voltage. Its getting .6v with my meter. I'm lost. I have swapped all relays that are swappable and no change. Link to comment Share on other sites More sharing options...

BoneheadJeeper Posted February 22, 2020 Author Share Posted February 22, 2020 Is there a NSS on these comanches? Would this have anything to do with no ignition power? Link to comment Share on other sites More sharing options...
jdog Posted February 23, 2020 Share Posted February 23, 2020 not usually, whats your ohm reading of the fuse link to b3? Link to comment Share on other sites More sharing options...

One side of the Starter Relay control coil, get B+ for the IGN SW (start circuit). The other side of coil is grounded through the NSS. Depending of NSS position (PRNDL) circuit is either OPEN or CLOSED for path to ground. Just got you message. Link to comment Share on other sites More sharing options...

We ohm'd from b3 to the starter relay, everything checked according to him. We went as far as using a jumper with an inline fuse, from the fuse box-b3 and still nothing. At the end of the day, he was stumped, and so am I. And also C267 is not a plug in my jeep. Link to comment Share on other sites More sharing options...

But the plug i took out of it looks just like the c268. Link to comment Share on other sites More sharing options...
