No Toad Brake Lights
Gary's thread (about diodes) has reminded me of a nagging problem that exists when towing our Honda Accord. When Smitty's (in Houston) set up the tow bar receiver on the Honda (7 years' ago), they installed a separate bulb in the tail lights. At the time, we had all functionality: turns, running, and brake lights. However, within the past 2-3 years, the light does not come on when the brakes are pushed. I replaced the "converter" box connected to the inside of the bumper, whose wires go to the 5-pin receiver on the rear end of the coach, thinking that would solve the problem, but no change. Since I use a Brake Buddy, when the coach decelerates enough to activate the auxiliary brake, the regular brakes on the Honda do light up.
The harness that plugs in to the 5 pin receiver "necks" down to a 4-pin plug that inserts into the front of the Honda. However, I am fairly certain that we initially had toad brake lights for the first few years.
I have had auto mechanics "look" it over, but none really wanted to delve into it, once they realized that separate wires and bulbs had been installed. Both bulbs work fine for the turn signals and running lights.
I am open to all suggestions, however, I am fairly "electrically challenged". I do know how to use some aspects of my digital volt meter, but not all.
