Locating the 7 pin alternator power wire

[Guest]

On one of the diesel sites, a guy was converting a horse trailer to an RV. For the brakes, he did something he called a "super capacitor" to power the brake EOH actuator then a NC valve between the EOH and the calipers so it would stay locked. There is always an option to do something similar with the break away switch. Power it from the TV to a capacitor that will apply and hold the brakes for XX seconds. Based on his studies, the brakes had to hold for 5 minutes (someone may know the exact spec).

If I get the specs on the capacitor, I'll post them.

Joseph,

A 5ah battery is a minimum for holding the brakes. The requirement is 15 minutes where in some cases for situations like a tri-axle or EOH a 9ah battery could be used.

So I asked about the capacitor. Here are the specs on them. He was using a bank of them for various things. Basically he was building a battery from them.
