Landcruiser V8 100 2003

Thanks everyone for the helpful advises - yes the electric brake controller is a Tekonsha Voyager! I will front up to an auto electrician for the doings.
Cheers / Carl

Yep. Just had to change mine. As soon as I disconnected the Voyager the problem stopped.

When the diode was installed did the vehicle & van brake lights still come on when only the brake controller manual control lever was used

Hi Don
The brake controller and brakes work as they normally would.
The events leading up to a diode being installed was that they (the son in law) were away from home for a week. The land-cruiser was in the carport locked up and their neighbor phoned me to say the brake lights were on in the LC. I pressed the brake pedal and the light went out so I left it. The next night the same thing so I disconnected the battery. On his return home he took it to an Auto electrician and a diode was fitted. Where or how I don't know.

I don't doubt that the controller & brakes will still operate as normal but are you sure the brake lights on the vehicle & van will still come on when the manual slide lever is operated

Hi Don
Give me 24 hrs and I'll ask the boy. he sleeping, come off night shift. He is an electrical fitter.

No worries

Hello again Don
The diode is fitted between the brake pedal switch and the Voyager brake unit. Cost is about $15 --- + some solder and heatshrink. The silver band on the diode goes on the brake unit side ie. the direction of current travel when the brake pedal is pushed. The problem arises when feedback from the brake unit occurs and lights up the brake lights. With the diode in the line the current becomes a one way street. The electric brakes work manually and with the foot pedal.
Hope this is of some help.

Stan

I understand where & why the diode is fitted but when the diode is fitted does it prevent the brake lights (on the vehicle & trailer) coming on (what you want to have happen) if only the manual lever is operated to apply the trailer brakes

Imagine this situation

You are leaving a van park & decide to operate the manual lever on the brake controller to confirm the trailer brakes are working & someone is driving to close behind you & runs into you because the brake lights did not come on

With a correctly operating controller the lights will come on but when the diode is installed do they still come on ????

Regards Don

Hi Don
I'll do a test on Saturday afternoon.

Hello Don
Your correct Don, the brake lights do not come on when the controller is manually operated. The lights only come on when the footbrake is used.

Yes i thought they probably would not work

I worked at a place where fitting a diode was the fix instead of replacing the controller but i am not sure this is the best way to fix the problem
