Anyone here have any experience with headlights and relay issues. Got a 01 RD688s that when the DRL relay is installed I have headlights that won’t cut off. Old relay was bad, replaced it with an updated factory replacement and now the lights won’t cut off. Pin 87a is always hot when relay is out. When probing with power probe and applying 12V to pins 30 and 85 I have low beams on one pin and high beams come on on another pin. Was told by my FIL that switch to left of dimmer controlled headlights only. Right side of dimmer knob does park lights. Coming from the car industry the way the relay pins are configured make no sense to me on this truck. I do not know if this truck is ground activated or power activated. I’ve tried doing continuity test with DVOM and have had inconclusive results. Same Flash to pass switch on top left corner works, headlights still remain on when the supposed headlight switch is disconnected. Headlights were working fine and then went out one day. Got a relay buddy to test relay and found it was bad, which turned into me replacing relay with AutoZone 5 pin, and then Volvo(Mack) relay with new part number since one in truck was superseded. At this point I don’t know if I have a bad switch or something else since lights still stay on when switch plug is disconnected. Only thing not working now is center cab light. Switch to left of dimmer turns on 2 outside cab lights, switch to right of dimmer turns on the 2 middle excluding the center cab light since we thing bulb is burned. this may or may not help but the high beam button on turn signal combo switch does not do anything to lights, at this point it is INOP. A few days ago we had an issue where right turn signal was not working, relay would click 1 time and then stop. Left hand turn was working as normal. I disconnected 7 pin plug from turn switch and disturbed some wires and has been working since. Could this be a bad turn signal combo switch or should I look elsewhere? I also ordered a USB drive from eBay with wiring diagrams for this truck, still waiting on diagrams but figured I ask on here first.

Never tried carrot chips, but I never met a sweet potato I didn't like. We make sweet potato fries- or chips- a lot. I never planted sweet potatoes but my dad grew them every year, and Zina just ordered some sweet potato slips from somewhere so we're going to plant a few this year. I never planted any because they take up so much room.

We both like the dill pickle chips you can find a some restaurants here in the south.

Bob,, I had a Tonya toy when i was around 22.

And yes blasters are amazing… bob

Not sure Joey,,,, I’ve had many Tonya toys ,,, somehow that one doesn’t look familiar…. Have a ball bud

There's this stuff called 303 Graphine. Comes in a small bottle more like something you'd find mustard in (black). I think it works great for bringing back plastics that are discolored.

becuase nyc is $4.2 billion IN DEBT. so it only stands to reason he should hire a freak that does not even know what sex he is for an alleged pay of $500,000 per year.

When I moved into my new shop I purchased a blaster cabinet and I had a 5 hp. Ingersoll shop compressor boy could that cabinet suck up air after 20 years of waiting for the air to build back up I found a 10hp. job with a 100 gallon tank it shuts off when I'm using the cabinet but it does make the meter run

I like sweet potato chips, we don't call them fries out here Even chips outta carrots are okay Paul

Yes, I didn't want to crack it! I was very careful with the heat.

Your hard on your toys Joey Struth, your tougher than a Tonka, wonder if thats like Chuck Norris type of tough Paul

Dam that loader brings back memories...had one as a kid.Great job Joey...Love the blaster too..... Paul

For what it's worth ? I keep a pack of birthday cake candles in the tray on the torch cart. I use them instead of WD40 or something when heating something like that stubborn stud.

If I didnt have this tool, I couldnt do it.

Eric Daugherty @EricLDaugh HOLY CRAP! Virginia Democrats just voted to EXEMPT THEMSELVES from their coming tyrannical gun control laws 2A ONLY gets violated for citizens: “The provisions of this section shall not apply to any member of the General Assembly who leaves a handgun in an unattended motor vehicle pursuant to § 18.2-308.7:1 when such vehicle is parked in any parking structure reserved for members of the General Assembly under § 2.2-1172.” This is insane. Elections have consequences, Virginia!

And check for the corrosion working its way back under the insulation breaking the wire??

Yep... I have been in the situation several times.. drilled out a few as well. Good jod sir..

Well, one step forward, one step back. The nuts on the turbo studs were marginal so I bought new locking nuts. As I was just snugging the last one.....zip.....stud came loose. 🤦 So off comes the turbo and I used heat to remove the other three studs to see there was barely any rust holding them into the manifold either. 🤦 Glad I hadn't folded the lock tabs on the exhaust manifold studs😲 Guess I will be installing helicoils in all four as the rest were not much to look at also once I unscrewed them. Ya, M10x1.5 threads. Why? Just because the stud threads for the nuts were m10x1.25. Ya, that is about the most odd thread ever. Just you can't get them at the local Ace hardware. Lucky for me I have two major bolt houses and it was something they carry. So, no more running until I get this to work and use the mill so they are nice and straight so the studs fit the turbo. Well, at least it wasn't in the truck? The last stud is being a real pisser. Letting cool and try later. I don't want to crack the manifold! I did loosen it off the motor so it could move around easier.

Sorry I thought someone would reply by now…. Your problem might be right there just pull everything loose and scrape everything. Nuts wire ends.Washers sometimes big issues are a very small. Fix Good luck.bob

I totaly agree.....

Probably. If I were to do it over again that’s probably what I’d do. Stupid though. Shouldn’t have to mess with that bs
