Turn Signal Wiring

[Curt Sprenger]

At the top of our Gen. Fan Compartment there is a 12V panel. In that panel there is marked "RH DIR" and "RH FRONT DIR (WL)", "LH DIR" and "LH FRONT DIR (WL)". The WL isolators are powered the same as the R/L DIR. What is the purpose of the WL isolators? Seems redundent but then it is a BB.

[Scott Forman]

I wondered that too, found these when I was trying to figure out a way
to separate the rear turn signals from the rear brake lights. I was
not successful.

That's exactly where I'm at today, trying to separate the rear turn signals from the rear brake lights.

I believe a brake light switch is located near the drive/tag axle. I'll check that out.

Curt, wonder if one is to the loom that goes to the trailer plug and
the other for the set that does the bus mounted lights. should be
an easy test to prove?

The front blinkers in the bus do not come on with the brakes 'the
wire to front blinker' would be a spot to trip a relay for blinker
only trailer. the brake light switch I believe is a air pressure
over electric switch on the service line???? just find the relay?
and use that signal to trip a relay.--- In

I spent an entire afternoon studying the blue prints and chasing
wiring trying to figure out a way to do it and came up with zilch.
One would think the turn signal circuit would be faily simple, but in
reality is has 8 or 10 relays and about a mile of wiring.

Take good notes, because if you figure it out, I am going to want to
know how.

Curt, if you have a electric brake controller, test that the 4 way
flashers dont bleed back to throw the brakes on and pulsate with the
flasher. the fourway flashers may be one other relay in the
mix????? here is a product to protect the bus from a ground
shorted trailer

tsbyvalley.html

it does what the fuse relay setup you built for my bus does except
thy need to fuse the battery input from the tug or tow vehicle(not
to be confused with 'toad'.

Curt & Scott,

If you are able to figure something out let us know please. I was not successful when I put the l.e.d.'s on awhile back. I ended up using the yellow lights to replace the back-up lights on the bottom. They are brighter than the old white ones were. Still would rather have the yellows for the turn though.

Gregory,

Sounds good. But, wouldn't you still have the reds coming on during a turn in the rear along with the yellows? And, what about the 4-ways?

Dick, I found this link for a signal-stat controller. the front directional and rear directional are wired independent. front blinkers dont carry thestop signal .thestop signal makes its way into the appliance. you would need one more wire to the rear to carry the brake only signal. unless you have a wire for a brake controller that is not used

[Curt Sprenger]

Brake and Lighits control to the trailer... Thinking out loud...

I''ve made up a new wire loom (6 wires). It will be installed, and it will run from the front of the coach to the rear of the coach. The brake controller "brake wire" (utilizes wire #1 in the new loom) from the brake controller unit, that is mounted in the drivers area, to the rear of the coach. Loom wires 2, 3, 4 (L, LT, RT) will carry their signal to the rear of the coach as well. At the rear of the coach, loom wires 1, 2, 3, 4 will be wired to a "4 wire to 3 wire" converter. The output side of the converter will be wired to the relay(s) signal (on) pole for the trailer wiring. The relay(s) output pole provide Brake, L, LT, RT.to the 7 pin trailer receptacal. Loom wires 5 & 6 are for "if needed" future wiring. I may use one for trailer back up lights.


How does this SOUND ???
