Good diagnostic, Eric! I noted that it was around minute 5:34, when you were checking pin 85 with the test light, that the LED went full brightness, and you hadn't touched the fuse yet. Maybe it was the relay socket that was making a bad contact.

[@rgmoore]

Agreed. At that point, Eric had his test probe connected to the ground, and when he touched what we would find to be the ground side of the relay, it got bright. I would suspect a bad ground somewhere. If true, it will be back.

I seen that. I suspect bad ground

[@craigwilliams4137]

Yeah, I thought the same thing.

[@calholli]

I did.. I was confused when he didn't explain what it was doing. (5:20) - His test light was tied to ground--- and when he tested that ground side (because he thought it was the power side at first), it would light up that little red LED, but not the test light. So for me, that means that the computer was sending a bad/weak ground control-- and he just gave it a good ground through the test light.... That doesn't explain what ultimately fixed it though.??? Maybe the bad connection was at the relay pins and he just scrapped them "clean" with his test adapter box...? He didn't really do anything to fix it--- it worked the first time he manually flipped that switch. So maybe it was just a bad/ stuck relay and that's it; and handling it made it break loose and work again for now.

[@imjohnny88]

It got bright every time McCoy turned the key. He finally noticed when McCoy left it on. He should really look back on this to be sure.

[@erisgilliard7341]

I think that is at about 6:40 when with the test light attached he had McCoy turn the key off and then back on.

[@rael5469]

12:55 We find issues with connectors or terminal blocks all the time on the airplanes. Many times just disconnecting and reconnecting fixes a fault. We have no idea what the actual cause is but just call it "micro-corrosion." Breaking and making the connection can clean it off enough to fix the connection. However in our case we try to always change the terminal block precautionary....as you did here with the fuse.

[@s.j.5850]

100% correct. The average customer who has been fleeced before by a greedy, unscrupulous shop will more than likely blame you for anything that goes wrong even though it is not related to the initial complaint. If it ain't broke don't fix it, just notify the customer what you found & tell them that it could turn out to be Pandora's box if you fiddle with it.

The LED went bright and then out at about 6:38 when McCoy turned the ignition off, Seconds later, when he turned the ignition back on, it came on bright, never to be dim again. For what it's worth, that's what it looked like.

[@gittnjiggy2]

Eric, at 6:43 minutes you had McCoy turn the key off then back on, the LED brightened and stayed bright.

Great diag, Thanks for sharing! it's always a pain when it fixes itself! It seems like the light became bright after he turned the car off and back on before you touched the fuse.(around 6:50) I really wish the uActivate had a built-in relay I would probably use it a lot more.

[@dougkubash8673]

I can understand!@@SouthMainAuto

[@calholli]

The moment that you fixed it is at 6:30) .. You switched your test light FROM power and had it probed into the power side of the coil and when he cycled the key on and off--- that gave it just enough juice through the test light to break through the corroded connection (wherever it is)---- which then caused your red LED light on the tester to stay bright.. even when you take away the test light. Before that, the little LED was always dim. So we never really found where the "issue" actually was................. You immediately flipped the switch and it worked as normal. You could have just thrown the relay back in there and it would have been done right then. Pulling the fuse and replacing, etc.. may have been the bad connection point, but we don't actually know; it sort of fixed itself before you could find it.

[@missulu]

Great video! The ones that start working when you 'touch' them are the toughest to diagnose!?! I've seen it in brand new equipment, and once I touched them they never acted up again.

[@mikechiodetti4482]

When you think you've seen everything, something new comes along. As fuses and other electrical parts age, corrosion seems to find a way to coat the connection points almost like it's magnetically attracted. Even in Southern California. I've seen that milky white coating. Hopefully, that's all it was this time. Good one Mr. O.

I have a 15 Jeep compass with that same setup. When the car was around a year old, it did this same thing as this patriot so the first thing I did was get into the enging compartment fuse box to check the fuses. After fiddling to undo the lid and checking some fuses with a test light I cranked it again and it started right up and has started fine ever since. That problem is still in the back of my mind and I expect it to come back at the worst time.

The way that Uactivate works is that when you hook it up, the color of the LED light at the bottom dictates which pin is the power side. In this case it showed 86 has the hot side. When you press the button on the top of the right side of the tool, the color of the lights indicates which whether or not 87, 87A or 30 is the hot side.

You were right, the PCM sends power to the control side of the ASD relay and fuel pump relay on earlier Jeeps.

[@josephcabrera6396]

I had a 2010 Patriot, same problem, it was in the relay box, one relay was so corroded that a prong broke off. To my understanding it was the rear most and close to fender relay that had the broken prong, but that relay was not in the starting circuit it was one of the middle ones. The broken relay was the relay that feeds power the the middle relay which is the one that was in the starting circuit. Since the broken relay was not sending power to the middle relay the jeep would not start. I actually pulled all the relays out and checked them. Had the jeep towed to my mechanic and asked him to specifically remove the broken prong and replace the damaged relay and that solved the problem. I had the jeep for 2 more years and the problem never repeated itself. But every 4 months I would go into that relay box and inspect and clean all the relays.
