Basically the fuse in the rear is to protect from any short due to an unforseen mishap (like getting in a car accident for example) If one does not believe in fusing a battery in the rear of the vehicle, then this same person may as well forget about a fuse under the hood just the same.
Thank you! This is the variable that everyone seemed to be missing, the unforeseen accident. All batteries, no matter how many you have, must be fused within 12-18 inches for safety reasons. I am using "fuse" to also include circuit breakers and fusible links. Whatever the means they are doing the same thing. To stop the flow of juice where a short occurs. Vehicle collisions happen more than we like to think about, protect ALL of your components by correctly fusing.
I am a fireman and have seen on several occasions collisions that were electrically devastating to the vehicle and all of it's electrical components due to the unforeseen. It is standard procedure to disconnect a battery from all vehicles at a collision scene. It protects all persons involved from trapped occupants to emergency personnel. I have also disconnected batteries and had the vehicles electrical system still fully functional! Second battery you say? No, the body of the car actually pierced the side of the battery and completed the circuit for the disconnected ground cable. Just disconnected the positive and no more problem.
Safety and protecting your equipment, that is what this is aboot. Who gives a crap about the rules?
I agree as well, I thought there was only one person arguing the opposit and I still do not believe that the rulebook says any different then this.
As an installer I have seen when people have not fused power wires and there is a black burn in their carpet from the batt to the the point it shorted and they were lucky it didn't catch fire.
what else can I say I am a grumpy asshole most of the time.
I am back and please let me be the first to admit that I was WRONG, DEAD (SHORT) WRONG on the rear fuse issue. Hey if a plumber from NY can prove information loss in a black hole is an impossibility to Stephen Hawking then I can certainly be wrong as well.
The fuse at the rear will prevent the rear battery from discharging if the front fuse has been compromised and the short happens in that wire run. The fuse is still there to protect the wire but I did not think about the rear battery continuing to discharge and "short" in a catastrophic failure of the front fuse. Please accept my apologies...
