There could be a couple of things going on here since the Roadmaster Battery Disconnect # RM-766 doesn't typically need to be installed on a 1998 Jeep TJ Wrangler. I would check the fuse box with the ignition turned off and see what fuses are still showing voltage and what the amperage is when the ignition is off. The other thing to look at is the Roadmaster Brake Light Relay Kit # RM-88400 that you've likely got installed; it's possible that the relay may be constantly energized and is... view full answer...
It could be that the lights # TLL160RK are malfunctioning but since the problem only occurs when the headlights are switched on for your 2003 Jeep TJ I think there is either a faulty connection or ground. Have you tried testing the 4-Way flat on your Jeep with your headlights on? If you haven't done that yet see if that makes a difference. You can also try testing your trailer with a different vehicle to see if it gets the same results.
Start off by checking the connector on your Jeep... view full answer...
Both trailer right turn and right brake light signals are carried on the same wire, a green wire in the case of the Hopkins adapter # 37185. Since these are the only functions not working I suggest you first test the green wire on your Jeep's 4-pole harness, the harness that plugs in to the Hopkins adapter. You'll want to look for signs of discoloration or corrosion on the contact pin for the green wire; clean as needed. If you have a circuit tester like # 40376 you can test that pin while... view full answer...
Thank you for your purchase from etrailer of the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56202. If the signals on your Jeep are not working when connected to your RV you'll want to check a couple things; we know it's on the Jeep side or the harness since your RV works when connected to your boat, so we can narrow it down.
The first thing you will want to do is unplug the harness and take a look at the Jeep's connectors just to make sure none of the pins were somehow... view full answer...
Since your 4-pole and 7-way vehicle connectors have correct signals and the trailer lights work properly when you hitch another tow vehicle, I suspect that there may be an intermittent problem in the wiring. This could still be on the vehicle side, or it could be on the trailer side. Older wiring can develop cracks and breaks inside the insulation that are not visible and sometimes the action of unplugging and plugging in a connector can make or break that circuit connection. A marginally... view full answer...
What you describe is a ground problem with the trailer wiring. Starting at the rear of the vehicle, confirm that the ground connection on the Plug and Tow Harness is securely fastened to bare metal. If there is undercoating, corrosion, or grime built up under where you attached the ground, you will not have a good connection. Next, examine the point on the trailer where the trailer connector ground wire attaches. This can usually be found on the trailer tongue. Make sure the wire is in... view full answer...
Since your electric motorcoach steps seem to be mechanically okay (the linkage and motor appear to function properly) I would suspect either a problem with the 12V power wiring to the steps or with the connectors that link the various parts. After 5 years in use these connections could loosen up and/or develop some corrosion.
The faint click could be due to a weak power connection that is not able to deliver quite enough power to the motor to activate the steps. Check your main power connections,... view full answer...
If I understand correctly, the line from the transmission to the radiator goes through a cavity in the radiator where there is coolant before the end of the line reaches the actual transmission cooler inside the radiator. Is that correct? Otherwise the coolant and transmission fluid would be mixing together and that would be very bad.
It sounds like the steel line needs to stay in the radiator and you would cut the hose and use fittings # D13028 instead of fitting something directly in... view full answer...
Even though the plug was found on the driver's side it does sound like your mechanic found the correct plug for the Hopkins # 42615 on your 2003 Jeep TJ.
If the lights on your Jeep are working normally then that leads me to believe that the wiring harness is messed up somewhere. Try piercing the wiring harness at different points to see if the signal is lost somewhere. Typically this would be a ground issue but if your ground is secure and connected to a clean, bare-metal surface then... view full answer...
