I noticed that fuse in the photo of Martin's jeep. Which wire should the fuse be installed on, and what size fuse?

Hey guys,

I want to thank all those who do not hesitate to step in this thread. Your guidance and sometimes your questions are leading me through some new things to learn for me. My learning curve is very steep… I would like to get the manuals but they are not easy to find.

So, I spent almost 24 hours on this Jeep in the last 2 1/2 days and it was really great. Full of good news. The future looks really good for this one.

First, we flushed the old gasoline from the tank. It was just awful and was close to get a nice buzz with, even outside of the garage. In fact, the tank was full… I looked twice on the invoice to see if it was written that the Jeep came with a full tank, and it was not! The gas is not cheap today, I was not expecting this special attention. :happy: However, I will have to change the tank or to bring to a place where they can apply a coating inside it. The tank is way to complicated to scrub. I don't think I can do it myself.

So, as soon as I can get a switch (I found one near me) I will go try the electrical system. The general shape of this Jeep is really stunning. Not a single screw did resist to be remove. The floor is all in great shape, except where the batteries drooled. Then, I'll try to find the gasket kit for the carb and resolve the problem with the gas tank.

I don't know yet how I will thoroughly clean the Jeep. How you guys do to have the cleanest engine compartment as possible? Are you putting the whole beast in pieces?

Finally, few pictures I took of the cleaning/assessing session.

Few other pictures. If you see something wrong on the pictures, feel free to let me know!

Other pictures.

The carb that I will try to make it shine!

Finally, the cleaning until next time...

Wire number 460/461, which is the power in to the signal system. I am currently away from my manuals (Mexican Mayan riviera) so the fuze amperage will have to wait.

Yes Rob, in the case of my short it was a light on the flasher that stayed lit. What it turned out to be was the wire running from driver side to passenger side turn signal across the top of the rad shroud/grill. The wire was bared from rubbing which caused the short. I also ended up replacing the solid state signal switch as it was NFG as well as a few light bulbs here and there.
For those not familiar with 24v military wiring, a good study of the schematic in the manual is always helpful.
Once again, as in past comments, I strongly suggest guys look at their wiring harnesses very carefully. Repair if possible with new wire where needed, tape, wrap and secure in place. If in doubt, get off the wallet and buy a new harness.
Electrical fires happen all too easily on old vehicles with tattered wiring.

What?! You really flew the nice cold winter season of Shilo to this poor little place to ended up with sand in your shoes and risking a sun burn?!

I have no idea what this nice cold that you speak of is. There are too many young ladies running around in skimpy bikinis to allow any thought process of what winter involves.

Well… I'm a little bit disappointed to see how fast you can change your focus but let's say I can understand if there are big guns around with very tiny canvas on them. I heard rust is not a big problem in this part of the world! The more I think, the more I could be distracted too.

Have a great time there and always keep your sunglasses on...

Cheers,

I really enjoyed checking out the pictures for this project. Excellent information provided by all.
Nice memories with the R. Wpg. Rif. and our AD Platoon, back in the 80's, I will dig up some pictures.
Where is the latest update on your vehicle Martin?

Got it, thanks Rob. Since there is already a connection in the 460/461 wire at the firewall, the fuse can be installed without cutting the wire. This sure beats the cost of replacing a flasher unit if a fault occurs. Also as Chris mentioned, it is way better than having a fire.

Enjoy the sun in Mexico! Its sunny here too, but -21C... and I don't see any girls like the ones you speak of.

Wayne Hingley · #14 11-01-17, 01:31

Bonjour Martin. Can you check the fuse for your flasher unit to see what its amperage rating is? Thank you for your help!

Martin Dauphinais · #15 11-01-17, 04:15

Wayne, I will but sadly, it'll take time as I will not go work on the Jeep until February. The Jeep is not near me as I do not have the place to keep it. It is in my friend's garage. That's a cheap answer I agree...

Wayne Hingley · #16 11-01-17, 05:50

Ok, no problem Martin. I don't really need it immediately anyway. Rob said he has the information in a document, and if he decides to come back from Mexico, I'm sure he will post it.

Keeping your jeep that far away is some form of self-punishment, isn't it? I'm sure you will have a list of things you will want to do when your next visit comes along. Cheers!

Martin Dauphinais · #17 13-01-17, 19:09

If I need a carb kit to restore mine, do I go on eBay or elsewhere. Like everything else, is there quality grades in these things?

Thanks.
