BETTER! As they don't lead to strain hardening failures or corrosion.

And way better still when a person has literally hundreds of wire ends to terminate.....

My crimps have always seemed a little hit and miss to me. I guess I need to do a bit of practice first. I never heavily researched until recently though.
Dimple goes opposite the seam!
Can you crimp more than 2 wires in crimp caps, how would you crimp 3 wires together?

I crimp up to 4 wires in the appropriately sized cap. First, twist the wires together and fit the cap on to the twist.

Next, crimp once near the wire entry.

Next, crimp again on the opposite side of the first dimple slightly higher on the cap.

A have started using bare metal brazed crimps with no seam. After double crimping, I do 2 layers of adhesive filled heat shrink. I feel better about dimple crimping bare metal rather than nylon insulated crimps.

When talking about crimping, all crimpers and terminals are NOT created equal.

A good set of crimpers and the right terminals make a huge difference.

Most sold at Wal Mart and parts stores pretty much suck, I wont use them.

Ugh!
Wish I hade gotten into this a long time ago, ie before I soldered some smaller joints that are now in the walls. They were in place of wire nuts that were there originally and were causing problems, figured a soldered end joint would be strongest best electrical contact. I zip tied the wires together back a few inches so there wouldn't be any strain on the solder joint itself, if that makes sense. Hope they last.

This will be one of my 2 regrets, not in order of regret.
1. Not crimping those connections.
2. Not using stranded wire for the 120v. The original was solid and had no real issues except there weren't enough outlets and I really HATE those push on RV outlets. I was really careful routing the replacement wire, lots of grommets, and split loom to help add additional protection and all attached to the skins so they aren't moving around. Not sure how I would have attached stranded to regular outlets though. I guess crimp rings. They're all attached with really solid connections in the shallow blue boxes.

What sort of adhesive do you fill with prior to heat shrinking?

You don't. The heat shrink I use is pre-lined with heat sensitive adhesive that activates as the tube shrinks. Be sure to buy the adhesive-type heat shrink tubing, not the plain type.

Brake wir junction

Thought I would share this with others. Took lewsters idea on the junction block studs from Waytek and ordered the studs, heat shrink terminals and heat shrink to connect my brake wires. Got my invoice today and the studs are on back order, they shipped 60 wire terminals and my 1/4", 3/8" X 48" long heat shrink tubes for $28.00 and charged 32.00 for shipping UPS ground for these parts and would ship the studs later with an additional shipping charge for them. Canceled the studs. The lady was very nice and is emailing me a 10% coupon for the studs when they come in around September, will look elsewhere. I told them to ship the cheapest way. They will ship USPS but I was told shipping would be about the same. So be careful if you order from them because they can't give you a cost to ship prior to shipping. They do have reasonable prices on parts but shipping is unreal. Live and learn.

Thanks Agent 86 for the site. I had forgot about them. Ordering the terminal blocks and shipping will be between $7 and $8. Big difference. They are now in my saved list.
