Re: Brake light switch
Perhaps you can find LED globes that operate 3v to 30v.

Re: Brake light switch
This project is to have a switched brake signal down the motor home, thru a connecter, into the toads connecter and then to actuate the electric braking system I have fitted to the toad. That braking system is a Blue Ox 12V system. LEDs wont cut it. I agree they are great, I have just bought some led replacement dash bulbs for dash gauges in 50 year old sports cars. They have come a long way.SteveW wrote:Perhaps you can find LED globes that operate 3v to 30v.
Re: Brake light switch
Zipid de do dah, zipid de day, dam good day. Thanks very much to Bruce & Terry for their valuable help in my problem. Today I removed the leads I ran to the earth side of the brake switch (I thought it was the light side). I then connected a lead to the other side of the switch showing 24V on the multimeter. That lead went to the relay coil. On the very large fuse/relay panel behind the dash I found a 5A fuse for the emergency bell. This 5A fuse is now the non emergency relay fuse. With everthing connected it works perfectly. The MH brake lights work as they shoud. The 12V from the relay is controlled by an illuminated toggle switch on the dash. It lights up as it should with the brake applied and feeds 12V to the rear 7 pin trailer connection. Now have to make up the cable between the MH and the toad. Was thinking of using curly cord but the prices are to high.
A lot happier than yesterday. Shows patience and good advise solves most problems.

Re: Brake light switch
Terrific news indeed.
Truck wreckers is about the only place I can think of that might have a curly cable laying around.
In the past I've just used a bungy cord to hook the cable up on my trailer. Originally got the idea from my Father............ he used to cut rubber rings from motorbike tubes when they really were rubber!

Re: Brake light switch
Cheap air compressor lines might do the job. Probably a PIA getting the wire down the guts though.

Re: Brake light switch
How does the whole electric brake thing work in the toad? when it gets a brake light signal does it just apply the brakes.... how hard?

Re: Brake light switch
Bloody hard if its set on the higher level. I have the Blue Ox older unit, can't remember the name, (all blue box) but I managed to get my hand between the pedal and the brake unit and hit the test button. Lesson learn't keep fingers out of areas where you should know better. Haven't tried it on the road yet but it sure does push the pedal down and bloody hard. Would love to see some brake meter reading on these units.

Re: Brake light switch
Have not used mine except for test, yes it pulled the brake pedal down well. I believe the instructions show adjustabe screws for speed of close and speed of release. They even say you should have someone in the toad to operate the switch and check both operations. They are then adjusted by the trim pots.Kelvin12 wrote:Bloody hard if its set on the higher level.

I am extremly happy with the older Blue Ox braking system. I have fitted mine to a Feroza 4WD and it is great. Just got to get the Blue Ox A frame mounted, maybe this week. Know I got the electrical right. ( I think)

Re: Brake light switch
There is an electric operated vacuum pump available for petrol engines to maintain the vacuum assistance on braking. Diesels already have vacuum pumps. Wouldn't be hard to hard wire the pumps if needed to operate and maintain the vacuum assist.

Re: Brake light switch
Hi Dirk, the older Blue Ox remote braking unit has its own vacuum pump that is plumbed into the toads vacuum line. This powers the power brakes even while the toad has no Independent power. Before anyone asks, yes the Blue Ox unit has a check valve so it cannot feed anything into the line when not operational. I have checked the latest Blue Ox unit and it does not need any plumming or extra wiring. Sit it behind the drivers seat, reach the claw foward to "grab" the brake pedal and turn it on. Don't know how it assists boost. Also don't expect to buy it for less than $AU1,600.Kelvin12 wrote:There is an electric operated vacuum pump available for petrol engines to maintain the vacuum assistance on braking.
