towed lights hookup?

[ernesttumbleston]

Here is a brain teaser! I have an 80FC with dual filiment 1157 bulbs
on the bottom and single 1156 bulbs on the top. The following is true
at the rear of the bus!

1. Running lights on bottom lights only as expected.
2. Brake lights work on all both top and bottom right side but only
bottom on the left. This also goes for the emergency flashers
3. Turn signals work top right or top left when selected as expected.

Why does the brake light not work on the top left side? This also
causes the left brake light on the car not to work. Note: this was
true before the car was hooked up.

Any help would be appreciated....And....It's good to be back...Todd
