Electric or Electric Over Hydraulic?

[FeatherFam]

Our RAM's factory brake controller has setting options for Electric and Electric Over Hydraulic. I am not sure which one to use for our 2016 Jay Feather. The RAM manual does not clarify which one to use. When do you use either setting?

Your TT has just electric brakes.

What is EOH for?

[Witt74]

EOH = Electric Over Hydraulic
I have seen kits available to convert your TT drum brakes to disk brakes. TT drum brakes are activated by electrically controlled magnets, the more current applied, the more braking achieved. The disk brakes, like the ones on your tow vehicle, are hydraulically operated, the more hydraulic pressure, the more braking achieved. The disk brake conversion requires a brake fluid reservoir controlled by an actuator controlled by the brake controller. Just as brake controllers are rated by the number of axles, not all brake controllers are not rated for electric over hydraulic.

So, the EOH setting is for towing a trailer with disk brakes, and Electric is for trailers with drum brakes - Do I have it right?

I have two electric settings: Light Electric and Heavy Electric. How do you determine which setting to use?

[Wireman]

I can't tell you that. Check the manual. I would assume it is related to the trailer weight you are towing.

Hey All,
Recently new here. Quick question. I have a 2011 F250 Xlt 4x4 with the 6.7
Hooked this up to our 17 Eagle 314BHDS, and I have no running lights. Have brake, hazards, and turn signals, but no running lights. I’ve checked all the fuses, replaced most, as well as one relay, but no luck. Replaced the port on the back of the truck, and nothing. Tested the port, and no light in the trailer light. Any ideas?
There is a setting in the trick for electric /eoh. It’s currently on the electric setting. Should I switch it to eoh? Or, leave it on electric? Would this have anything to do with the running light issue? Thanks in advance.

The brakes are totally independent of the lights. So you controller should not be the issue. Only common item it has 1 wire in the 7 pin harness and the ground.

I would recommend determining if the issue is with the tt or tv.

My 1st thought, is a loose wire connection where the 7 pin harness connects to the tt wires. Simple test of the tt side, place a 15 amp fuse in the 7 pin harness, across the two terminals, that span the "key". One side is the aux power from the tt battery, the other terminal is for the running lights. Lights turn on, the issue is with the TV. If not, the issue is with tt side. With all the light not working, follow the 7 pin wire harness, to where it transitions to regular wires. Take a photo! The issue should be with the brown wire, and probably a loose connection.

On the TV side you can do the same thing at the pins, but you need have the tv lights on, and a multimeter. Much easier the test the tt side.
