We have a 97 International with a Blue Bird body and when the door is opened, the stop arm starts to come out a little bit then slams closed, and keeps doing so until the door is closed. I tried a new motor, plastic clutch, and switch. I figure it's grounding out somewhere keeping it from staying out but no such luck finding a bad wire yet. Any tips are appreciated! |

Does this bus use a Weldon Block? |

I hate to display my ignorance on here, but I'm not sure what a Weldon block is. I trained with the mechanic here for a couple years before he retired and now I'm on my own, just doing what I can and trying to gain experience. |

Is it an SMC stop arm? being a 97 I would assume it has the Weldon 7000 flasher unit in it(I believe is what Bfaulkner is refering to).. so stop arm receives power from that flasher, when reds are activated.. it should be under left dash/switch panel beside driver, non of my Bluebirds that old had a side door on them so had to remove dash panels to access flasher and test.. most electric arm problems I had here were due to bad micro switches or motors ..the way you explain yours sounds like a micro switch inside arm malfunctioning to me.. sounds like arm is getting power...but could be ground issue too.. If it is an SMC electric stop arm, the ones I had were always problematic with micro switches and or parts/cam that rotated to activate micro switches... They offer a solid state unit that replaces all the plastic switches and other junk inside of the stop arm.. I prefer the air units and don't have any electric arms anymore but had switched all of mine I did have over to the solid state units long before they were retired from fleet... had much less problems with stop arms after that! Doesn't seem like solid state unit was that expensive per-say compared to all the labor we put into keeping them working before switching over...Good luck |

yep, what slippert said. I would ad that you might suspect the "block" (never heard the Weldon 7000 called that either). Can you try one from stock parts or from another bus? |

We had one doing something very similar and it was the Weldon unit that was the problem. However, ours are air operated not electric, so a bit of a difference there. |

Yes, its old and does not have the side door on the outside. I already removed the dash panels looking for bad wires, so I will definitely check that unit next. Thanks for the comments guys! |

So it did turn out to be the inside unit, only I didn't have another 7000 series but the SBF90 model (the skinny black one.) The stop arm and ambers are working fine but the right side reds are not coming on. Could that be anything besides a short in a wire? Wires seem fine but if that's pretty much the only case it could be then I'll do some more digging. |

The Weldon unit has a tab for right side reds. I would say you have a problem with the new unit being not compatible or not good. Change the wire to put power to the right reds to see if that eliminates wire issue. ED |

I've changed the wires around and ended up with more issues. I did question if it was compatible or not and just assumed it was since everything worked, minus that one problem. I'll try one from another bus to find out. |

The InPower flasher referenced is a direct replacement for the Weldon 7000. Do you mean the arm deploys and BOTH lights work or is one light also out on the arm?
Sounds like you got a defective one (flasher) or there's a dead short in the red circuit for that side. I'll put my money on a short.
Do you have a light monitor? Those newer ones have on board fuses to check. |

No light monitor. Yes, there is also one light out on the arm. No red lights on the right side of the bus or the bottom light on the arm. |

As dumb as this may sound, did you happen to replace the lower stop arm bulb? I had one that I put the wrong bulb in and one side of the upper red lights would not work. |

Certainly does sound like a dead short opening the circuit protection in the flasher. Good tip on the sign bulb, I got burned by that once too. |

I changed the bulb and still nothing. I also put a different flasher in to see if the other was defected and that didn't change anything either. Seems like the things you expect to be simple always become the biggest projects. |

But is it the correct bulb, an 1156DC (double contact) or did you put an 1156 bulb. Common mistake, usually only once per person though :) |

Unfortunately, yes it is the correct bulb. I was hoping it would have been that easy. |

I'd pull each fixture from the affected side and check wiring at that point. Could be as simple as the hot wire fell or broke off of the bulb and is dead shorted. These new seal beam bulbs we get now have such sloppy soldering for the terminals that sometimes the things are laying loose in the box when you open it. |

or have solder boogers so huge they touch the housings they go into. had that one happen on a fog light i replaced. |

I thought it was just our shop buying cheap bulbs! Glad I'm not the only one to get crappy parts! :P |

One of my favorite things to do is look at both the old and new bulbs and see if they are stamped CHINA or MEXICO. I haven't seen a USA for years. I'm easily amused. |

Funny thing is, we would all love to see USA again! Problem being, we don't want to pay the price. If you were to talk to me personally, you would know I'd be talking about voting for a certain presidential candidate right now so we can get more USA parts like that. lol But I will keep the politics out of it like the people who own this forum want. |

You can still get bulbs made in USA. I try for made in Canada 1st, then USA. Can we say names here? Starts with S ends with a, I have been getting made in USA at a cost the same or slightly more than china. |

Glad this wasn't wheel of fortune with a $30,000 prize because I'd have just lost out. |

So I know it's been a long time since posting this, but things piled up and I hadn't had the time to work on this until this morning. First thing I did was touch a jumper wire to the right red wire on the module, and what do you know, it worked... That simple the whole time. But oh well, glad to get it all put back together and out of my hair! |
