hello can anyone help me going mad. trying to install 1985 taillight assembly in my 1986 244. put the newer circut board on the 1985 taillight. almost everything is functioning properly brake light works with the running lights off. with the running lights on it appears that both filiments are lit it is wery bright.then when u hit the brakes the bottom right brake light goes out and you get nothing. and the running light goes out in the same square.when the brake light goes out. wasted alot of time. sometimes fuse blows when trying different fixes. cleaned the ground screw location real good. maybe this 1986 circut board wont work with the 1985 taillight assembly. also put bulb grease on the connections.electrical not my best quality. 1985 244 162'000 1986 244 106'000 thankzalot.
