Ok, so I know a bit about car mechanics, but not much about busses, but being a small church that makes me the one in charge...

We have a 93 international 3800 amtran, that has a Weldon 7000 light flasher system, and one- the lights do not flash at all, and two- there is a buzzing coming as if the emergency door was open..

The weldon had 2 wires disconnected, and 3 open pins- pins 8, 9, and 10.. one wire is a thicker red wire and the other is a thinner white wire.. any ideas?

On your first question: is it legal in your state for a bus not transporting school students to use 8-ways? Perhaps the seller disabled them for legal purposes. If it is legal, terminal 8 is the start switch, so probe for +12V when you press the switch to start the lights. Terminals 9 or 10 are hooked to a door switch which goes to ground so you can either have the reds come on only after the ambers have been activated, or any time the door is opened. All our buses are wired the former way, to terminal 9.

Here's the manual for the flasher if you want to know more: http://www.akronbrass.com/media/pdf/File-1326141540.pdf

Second question: if it sounds like an emergency door, then maybe it is an emergency door. Check the switch.

well, not sure that it is legal or not, but I was just wondering if that might have been causing the buzzers. But, I just did another walk through, and one emergency window's latch was open, and on the emergency back door there was a little latch at the bottom of the door that wasn't latched open so it thought the door was locked shut... but closing that fixed it!

If those door hasps aren't open, your bus won't start. Safety thing so kids can escape...

The laws do differ some state to state, here your bus would no longer be required to have the flashing red and amber(yellow) lights. Since it is not being used in the capacity of transporting school kids to and from school to home. A bus being used by a church would be classified as an activity bus and does not require a working 8way system. The small latch on the bottom of the door should be a vandal lock. These are used for anythime you have the vehicle parked and dont want anyone to gain access by opening either the emegency door or the emergency window from the outside of the bus. These locks will sound an alarm and lockout the starter. That is a requirement on a school bus. In the event you want the 8-way system working check your red wire with a test light. Start the vehicle activate your 8-ways with the switch and see if your red wire has power. This should be your start switch power, pin #8. Then the thinner white wire should go to either pin #9 or #10, depending on what sequence you would like for your 8-ways. I have buses wired both ways.
