Hey - Sperry or anyone else who knows what I should do,
I did the traditional 4-way brake mod with the diodes to trailer harness and I'm having trouble with my trailer lights when hooked up. There is a serious delay, if my turn signals even blink, when I brake and use my turn signals. You had mentioned LED lights w/o load resistors; where you talking about the trailer's lights or the AVs brake/turn lights? If you were talking about the trailer, would it go back to normal if my trailer had the LEDs brake/turn lights?,
Any help would be greatly appreciated,
Troy
Yes, relays are only needed on large trailer brake/turn loads.
Mine worked the same with or without a trailer connected. The diodes I added were for the upper to operate with some more logic: Both will show on turn or brake. The brake overrides turn on the upper and the turn overrides brake on the lower.
If you just brake, both will light (each side) OR if you just have the turn sig on, both will flash.
You need the (3 to 6 Amp) diodes if you want this (upper) functionality added to the lower turn/brake mod.
However, fot those whom hadn't done it yet, and If you want to just add brake light function to the lower lamp's turn function, you route the trailer turn & brake signal wiring to the lower lamps, and remove their original wire connection. No diodes needed for this.
The fuses for the trailer turn & brake (in the left dash fuse panel - 03+) are just 10Amp for each side. A brake light filament draws around three amps each and with a simple trailer, you are running up to three filaments through those fuses, in turn signal mode each side, with how I did the (complete) mod.
So far, I hadn't needed the LED mod.
In brake "mode" the upper filament is sourced in combination with the original wiring, isolated with the diodes..
If you used 1 Amp diodes such as a 1N4001 through 1N4007, per se', you could have overheated it with the load and shorted it. Now the circuits have lost their isolation from one-another and weird things can occur.
If a "trailer brake and turn" fuse is removed or blown, with this mod, the turn flasher will flash rapidly.
I hope I didn't leave you too confused.. Perhaps more info as we proceed...
