Maybe the "smart start" boxes have a relay or FET switch controlling the starter. Unfortunately I have not found any board level documentation, there are allot of different boxes. This does not mean they are not out there!!:) I generally just go in and trace the circuit I am having issues with.

Have you tried it with the inside plug pulled off of the EESS and the outside plug connected? If so then it must be in the box, could be full of water among other things. If you only have the inside plug removed and there is no start signal then it is in the dash wiring.

Good question!!

Not likely the EESS, the start circuit just passes through the box, You can disconnect both connectors and try. You can also slide under it and disconnect the start lead from the starter. BE VERY CAREFUL!! that arc at the battery can cause a battery explosion, wear safety gear when messing with...

OK, in my world they call that reverse polarity, nothing electronic that operates on DC likes that, I would suppose the HMMWV 12V tap (the only one that can get subjected to reverse polarity) probably has some protection because everyone that is using a single switch on the ground side of their...

What do you mean by false ground

Bunches have turbos, they are the ECV and the REV. that measly 30 more HP is not allot of help. Have you ever driven a HMMWV? If not try to find one and drive it, I suspect you will give up any hope of pulling a horse trailer at highway speeds

Its got EVERYTHING to do with power and the Detroit just does not have it.

Swapping to 2.56 gears will make it worse, you can in theory go faster but that Detroit ain't got the guts to pull a horse trailer

Not going to happen unless you are going down hill, even with 30 more HP

Not at all true,,,, You can have all the gears you want but if you do not have the horsepower there will be no speed just bog. Otherwise we could set world speed records with lawn mower engines, it takes horsepower to go fast, that is why as aerodynamic as a Bugatti is it still takes 1000HP to...

What it is like passing a stock HMMWV with a M998 with a 475+HP Duramax :ROFLMAO: https://www.bing.com/videos/search?q=ludicrous+speed&&view=detail&mid=16147C4A926C5C1334FF16147C4A926C5C1334FF&&FORM=VRDGAR&ru=%2Fvideos%2Fsearch%3Fq%3Dludicrous%2Bspeed%26FORM%3DHDRSC3

Yes, the turbo has a higher rear end gear ratio than the NA

The advantage to using a ground side switch for the 24V is if any of the cable or connections accidentally finds ground it will not start a huge fireworks display. If you use a dual switch, one on the ground side of the low side battery and one disconnecting the 12V connection between the...

Then you have to have two switches or a dual switch. If you break the connection between the batteries and leave the 12v connected to the high side battery (neg) you have the exact same situation you had when you disconnected the ground side of the low side battery the 24v stuff will seek ground...

No

If you disconnect the ground and the lead to the connection between the batteries (12V) nothing will have power, you do not have to disconnect the connection between the batteries.

That switch is made for a dual battery system like a boat with dual batteries, not meant to switch a 24V system and the 12V component. That requires two separate switches, completely isolated from each other weather or not it is controlled by one mechanism, It would require 4 poles not three...

It boils down to how much sweat equity, time and your tolerance for risk, buying a surplus truck is a crap shoot and as stated can take up to a year for all the paperwork. It is much more challenging to work on than a Jeep, access to just about everything is much more limited, you will loose...
