Will dangers described apply to following? Tow 2013 Ford cmax auto transmission behind 2024 Itasca sunstar 27N class A. Installed Demco Stay in Place permanent supplemental brake system. It has a toggle switch located in rear of car to turn on when in use. If system on while completely hooked up and key breaks when test, will turning off toggle switch keep me safe from electrical danger until can get replacement? Would other better option be to test key with supplemental system off, car off, and car not hooked up to tow at all?
Maybe, but test if for yourself. Next time car is to be towed and is hitched up, leave the switch off with the key pulled and see if the brakes hold or not. Do not move very far ahead or move ahead at all, just see if there is any more resistance than normal when trying to pull forward with very light throttle, especially if having a powerful diesel engine for the coach. If the towed cars brakes do not hold, key pulled and switch off, then you know the switch shut the system down. If the brakes do hold, switch off, and key pulled, the switch will not help in a broken key pulled situation. I however wonder when a key breaks, where does it break? Inside the switch so the switch fails in a breakaway and the brakes do not apply? I had a 25-year-old trailer and pulling the key never broke it. Well, maybe it was not made so cheaply as those today.
Looking forward to the e-current draw testing you referred to in today's article. Thanks.
I think there’s an easy way to do this. I’ll test it on my GeoPro RV and shoot a video as well.
