Got 4/0 cable and terminals and made all new from the starter to the batteries. I also replaced the boost solenoid and the isolator. When trying to remove the nuts holding the cable terminal to a component most of the time it twisted off. Good luck with your problem.

I think I will do the same. Thanks again Ron

We used a strap around heavy starter and then over something above starter allowing us to lift the heavy starter by pulling on strap from outside coach.

Good idea. I will remember that.

Most important thing, particularly considering both your time and $$$ is to VERIFY the problem and solve it rather than approach it by just replacing parts.

If you do decide to pull the starter you'll probably need a 5/8 or 3/4 twelve point socket and a foot square piece of 1/2 inch plywood. You go underneath put the wood on your chest and slide the starter out toward you then onto the wood, they only weigh 20/25 pounds. So if you don't drop it on your head or something else you value it'll go back just as easily.

I had a starting problem on my 99 U295. I added two 4/0 cables, directly from batteries, one to the starter and other to frame and left everything else as is. I also added another battery. It solved my problem. I did this about 5 years ago and never had a problem since. Might be worth a try before removing starter .
Just my two cents

Ron,
So, if i understand correctly. When you say you "added" two 4/0 cables, did you leave the existing cables in place and just added the new cables or you replaced those two cables?

Thanks everyone for your input, much appreciated as always.

I know I will probably have to get my old cables off for accuracy but, for those of you who have replaced yours, do you recall the total lengths for each cable? I am planning to order these online. I can guestimate the lengths but I rather not buy cable I won't use. At the moment, I am not able to get  under the coach to run down the dimensional lengths.
Thanks

I added the extra two cables. I drilled and tapped a new hole for the ground. This gave a direct flow from batteries to starter and ground. I didn't like the looks of the terminals by the batteries. they were the originals. Be sure and secure cables all the way so they won't rub on anything.

Sounds like a plan. thanks Ron. I have discovered in cleaning my cables, the insulated standoffs on the frame @ the batteries, the stud is really too short. Drilling a hole in the frame for the negative side, i can do, but what did you do for the pos. side? I saw online where I can use a triple standoff and that is what I am considering at the moment. Ideas?

If you want to add a new tool to your kit (both literally and figuratively) then you could learn how to make your own HD cables.  At the urging of other Forum members I picked up this skill.  It's not hard, but it does require spending some coin for tools.  I know I risk derailing this thread by mentioning this subject, but hopefully others will resist the impulse to start another raging debate over "which crimping tool is best".  You can search for old threads on this subject to read the pros and cons.  Just be aware that you can make your own cables if you wish.

One way I use to find bad connections is after starting the engine or trying to start the engine
is to go back to the battery right away and see if I can fined any warm connections.

+1 on the purchase of battery cable crimper. I purchased a premium one and you'd have to pry it out of my cold dead fingers. Handy for solar also. Save so much money.  Sorry to derail.

I agree completely Chuck. I had looked at them once before but seemed a bit pricey. I will take another look as I prefer to do it myself anyway.

I know there are many qualified people who work on these things for a living but having been a auto mechanic my whole life, I am just biased I guess and prefer to all the work I can myself. Strangely enough, out of all my tools, a cable crimper is some I never had but it looks like it may be time to get one. Thanks for mentioning that,

looking into my battery compartment, look at the lower left cable. It is cracking and deteriorating like this from one  end to the other. Looks like it got super hot at some point.

Definitely need to replace that one.

I removed all of the old cables and installed all new. I didn't trust the old cables to not short out. I have a crimping tool that I have had for years. I made all of the cables. If you do your own cables, much cheaper. If you do them, be sure to get a cutter for cutting the cable so that it is nice and smooth so that it will slide into the terminal. I used red for positive and black for negative. Foretravel had used all black cables with red heat shrink on the positive.

The way things are going this "Winter" that will probably be in a couple weeks.

In Midland all the fruit trees are full bloomed out and the fruitless mulberry trees are budding.  They think it's Spring!

Hey Chuck
Here in Longview, we are already having 70 degree and up humid days. It is ridiculous.  We are taking the coach out for the first time for a test run to a local lake 25-30 miles up the road on 3/16-17. If that all works out ok, I will start on the cables the following weekend if I can borrow Mike's pit, LOL

Zach, be sure that if you still have the OE serrated anti-rotation lugs, they must be changed out, or at least filed down if they are not paired to the same type of serrated connector.  It looks like that's what you have on the end of that old cable connected to the new standoff lugs.  I had massive overheating when I connected these to flat brass ends of a shunt...loss of surface contact and high resistance.

Yes, those are what I have. Wen I get new cables, I am planning to change all the lugs out to the smooth surface ones. Thanks for mentioning that, I never thought of the overheating issue but it makes perfect sense. 👍
