[VAC] Re: Charge line fuses

[Inlandrv@xxxxxxx]

12 volt self resetting circuit breakers are used in charge lines. Typically 
40 amps. NEVER, EVER, use any form of any kind of fuse in a brake line. To do 
so is asking for disaster. If a short in the brake system did develop, some 
braking would still take place. It might not be enough, but it certainly is 
better than zero.
Shorts in 12 brake systems are almost always related to poor or lack of 
proper care. Magnets do wear out and must be replaced, before they wear into 
the plastic insulator. When a major brake is done every 10,000 miles, as it 
should be, worn magnets will be caught before they can short out. Magnets are 
normally good for about 20,000 miles, on an average. Additionally, if someone 
has towed through high grass or weeds, or rocks, it would be very wise to get 
underneath the trailer and check the wiring for damage.
There is no substitute for proper maintenance. Fuses and circuit breakers are 
great, but only if they are used correctly.
