Testing Break Away Switch
Can I test the break away switch on my Argosy?? I know they are "cheap", but if I can put a meter on it and test the one thats there why spend the $25?

I think the easiest way is to be hitched up to your trailer, then:
1. Disconnect your 7-way umbilical (this will prevent damage to your brake controller)
2. Pull your brake pin. Note that this pin should never be out for long, so be ready to proceed with step 3 immediately.
3. Gently try to move your trailer. The wheels should be locked.
4. Go and put the brake pin back into the breakaway switch.
If the wheels did not lock, check to see if your trailer battery is connected (this is what powers the brakes when the pin is pulled).
There are several postings on this subject if you need better help than this.

If one person is placed near the axles and one pulls the breakaway switch, shouldn't the brakes start to hum? While this wouldn't detect effectiveness of the brakes, it should determine if they are getting power.

Breakaway test
Put a test light to the non powered side of the switch and pull the pin, or pull the pin and put a compass close to the wheel, it will deflect to the drum because of the magnet, or the surest test is to jack up a wheel and try to spin the wheel with the pin pulled.

Testing break away
Whats the Worst that would happen, if for example, the pin had been removed from the switch for an extended period of time..( days...)? Would it create a " mystery power drain"... and also, would any damage come to the elec. brake system of the trailer or brakes?

If the brake system is in good condition, then all that would happen is that the batteries would go flat trying to keep the brakes applied. Inconvenience? Yes! Damage? Probably not.

DO NOT leave a break away switch pin pulled for more than 5 minutes.
If left in the pulled mode long enough, it can burn up the magnets and detemper the axle spindles.

We tested ours once. Sandwiches near a big truck stop, and decided to turn sharp and go fill up afterwards. Slight bind in the pull line, and zonk! We were stopped deader than a doornail. Boy, were we ever glad to discover that the pin can be reinserted!

OK. Well, I'll guess I'll find out this weekend ( when I have the time investigate further). Thanks!

What the world needs is a breakaway switch that not only applis the trailer brakes, but also disconnects the line to the brake controller so as not to fry it when testing.

I know it is an inconvenience to send it back but there a lifetime warranty on Prodigy according to their web site:
