The front blade hydraulics are done!! Kind of congested but they work!!

It's ALIVE ....finally

Everything works but but I have two problems.

A couple of hydraulic leaks on the just rebuilt cylinders. Time for a conference with the hydraulic shop.

One electrical problem to chase down. When connecting the battery, I get a good spark...with nothing turned on?? Any ideas where to start??

Looks great gus. Such a nice job on this build.

Finally got it on youtube....

This was the first drive. The hydraulics are soft as I was working the air out. I had to remove one cylinder today and have it re sealed by the hyd shop that had just rebuilt it. I haven't put it on yet.

I have all the small problems resolved. The hydraulic shop found the problem and fixed the leak. I chased electrical for 2 hours and finally found that the regulator had a short. A new regulator has fixed that. You might have also noted in the video that the right track is tight. These tracks have been sitting for several years (not original to this crawler) and I'm going to run it some to see how much is rust. Once it's been run some, I'll readjust them. I've also made some tracking adjustments. The clutch needs a little adjusting too. It needs to be worked!!

Question??? I special ordered the 6V positive ground regulator (must not have been too special I had it out of stock the next day) and it came with a resistor to put inline on the F terminal. I did and everything works, but why??? Why the resistor?? The regulator is an exact duplicate of the one I had (minus the short

).

A resistor limits the amount of electrical current that passes through the circuit.

Think of kinking a garden hose. The kink "resists" the flow of water same as a resistor limits voltage.

Do you need to reduce the voltage past the resistor location in the circuit? If yes, leave it in. If no, you can run without it.
Where is the resistor in the circuit?

Just to add to what 2006 said. You have to watch terminology here.
If the resistor is in line with F (F wire hooks to one end of resistor then other end of resistor hooks to "F" terminal on regulator (and that's the only connection on "F" terminal)) then it is like a series circuit and will change the Voltage, not the current.
If the F wire AND one end of the resistor are on "F" terminal of regulator and the other end of the resistor is attached to another terminal then it is like a parallel circuit. In this instance it would change the amount of current and the voltage would stay the same.
Sounds like you are adjusting the voltage. It could be that the regulator is a 12 volt regulator and your dropping the voltage down to 6V for the regulator to function properly.

It is in line. Drop from 12 to 6??? Nothing 12V in this system. The regulator has a sticker on it that says 6V positive ground. I'm still not sure what it is for and if I ever open the dash again, I might remove it to see what happens. It seems like I'm getting less amps on the guage.

It likely is a universal VR and was on there to cover various applications.
Look in the service and parts book. That would be my guide.

I'm thinking like 2006. It's universal for 12 or 6 volt and when it got down the assembly line they put a 6 volt sticker on and packed a resistor with it. At least it works good.

No resistor needed to go from 12 volt to six, a resistor would be used if it was the other way around. My guess is that it is not a resistor, possibly a diode.

I just looked at the instructions again.

It is a resistor but....my generator is NOT on the list is says to use it with.

I think I'll be removing it.

I think it might be for older tractors that used a cutout or old style regulator. There are diagrams for rewiring them included.

I would get the correct regulator for your crawler before it wrecks something else, they are readily available, no sense chancing it.

The regulator is OK. It's just the resistor kit with it that was different and had a list for older units that mine is not on. My gen is not on the list and is to be used without it. Appearance wise, it is exact with the one that was on it, same size and terminals.

I removed the resistor and it is working fine. No real change on the amp meter and it shows charging as needed.

Question... I have an extra generator and it is missing the small spring which pushes the brush finger down. I think it also holds the finger on at the same time. I will want to clean it up and check it out for future use should I need it. I have 3, all the same, and this one would be the spare.

Must be for some odd application, glad it is working.

Well, I just HAD to find out if it is to wet to work ....

The answer is, yes, it is

Ok...that's not all I had to find out.... this was after I removed most of the mud in the track frames.

This is the first work done...my regular video op was gone
