I have an 89 International Bluebird TC2000 Flat nose bus.
It has 4 tail lights with independent filament combo bulbs, with separate turn and backup lights.
recently I attempted to put a temporary 4 wire trailer plug on it at the tail lights. That endeavor eventually failed for the need trip as the weekend trip progressed. It all worked fine when the trip started. When we attempted to return home we found no functional tail lights as we attached the trailer. After removing the temporary harness and returning it to factory I now am faced with no tail lights and brake lights that only work on the drivers side. After the bus sits for a short period (one or two days) all the brake lights work. All of the tail lights work until, you combine the two. With the lights turned on and all working then applying the brake the passenger side does not work as before only the drivers side illuminates. After it sits for between 5 to 10 minutes with only the tail lights not the brake lights. The tail lights start to dim until out. They will not come back it seams for a day or two.

Your probably looking at a weak circuit breaker. |

Question(s). So you are saying, that if you apply the brakes, the brake lights work or if you turn on the tail lights by themselves they work. But if you turn on the tail light and apply the brakes thats when things get stupid ? If this is the case, it puts me in mind of a ground issue, pull your lens off and check the ground straps, loosen and retighten the ground screws. Or possibly back feeding B+.
One other burning question, and don't get me wrong, but what state are you in that allows you to hook a trailer to a "School Bus". If I tried that in Iowa, I would be chewed up spit out and booed off stage.

Your understanding of the problem is correct. It is a privately owned bus, and I am in Georgia. |

Dang sure check your grounds, ground screws. After all electricty is FM ! Or so it seems that way.
It could very well be that you are dealing with two problems that started at the same time. The tail lights suggest a load issue just like Bwest said, weak breaker tripping and then cooling down. |
