12 volt connections... in your opinion what is the best? In the past I've used these linked below. Is there anything that makes a good connection and is removable? Thankshttps://www.delcity.net/store/Terminals/https://www.delcity.net/store/Vinyl-Insulated-Butted-Seam-Butt-Connectors/p_805413.h_801846.r_IF1003?mkwid=sJf2vX39z&crid=38094426869&mp_kw=&mp_mt=&gclid=EAIaIQobChMIr-zZjO7G2gIVBKrsCh27mw-HEAQYBCABEgLw9fD_BwE

Where possible I use solder and heat shrink tubing to make a secure connection.

I use ones that have solder in the middle and heat shrink, heat with a heat gun and it's soldered and sealed in one step.

If you properly swage (crimp) connections, they actually cold weld to the copper or tinned conductors and as such are gas tight and internal corrosion will not be an issue. This is very hard to do with the tools that leave the external insulation undamaged. Those tools that have a single tooth will always do a better job of this. This also requires that you use first quality terminals. Those with a heat shrink insulating sleeve will reduce corrosion of any exposed conductor and serve as a better bend relief. The vast majority of connection failures are at terminal connections. The reliability of these connections can be significantly improved by covering all the surfaces with a silicon "dielectric" grease. This product is grease, but is different than any lubricating type grease in that it has zero film strength. This means it is useless as a lubricant, and when it is in an electric connection will not interfere with any of the metal to metal connect that is required in this situation. Why do I know all this? As a ship's engineer by trade that ran a small vessel maintenance company up until the administration caused depression put us out of business. I sold of most of my expensive inventory, but kept the field boxes of terminals and tools and several tubes of silicon grease for my own use.Matt

I just finished a 1300 mile tow of my car. Which hasd a lube pump. about 500 miles into the tow the pump alarm went off. I was only a few miles from Parked so I fired up the car's engine to pump the fluid and finished the trip

There have been a few issues with this pump. The original pump failed. so it was repalced. this one blows fuses. So I tried a circuit breaker, Promptly blew the controller.. I should have de-engineered further on the controller and found if I could just beef up what failed but alas. I did not.

So I added a relay The power to the relay contacts is tapped into the power to the controller line with FOUR, count them FOUR "Stocth lock" type connectors ALL FOUR FAILED

now spliced and soldered SOLID.

Either use non-insulated splices/terminals and a separate piece heat shrink or splices/terminals that have shrinkable insulation.

Done correctly a crimped connection is just as good and some way netter than solder.

If you are running new wire, use "marine", pre-tinned wire. This greatly reduces corrosion.

I hate Scotch Lock taps ! I will not use them and if I find them i critical places I replace them !!

They are the worst.

I use butt/bullet connectors and put heat shrink tubing around them. If I need to take them apart I slit the heat shrink and pull them apart.

Yes; Weatherpack connectors.

We use them on race cars and I will not use anything else now. They are the best. Yes, they are expensive but they also won't come apart and they are water proof.

I knew the brake wiring on my new utility trailer was undersized so I thought I would look a little closer before I run a 12 G blue wire from the 7 way harness back. Another problem is that they used a cheap 7 way cord that is 16 G.

They did use heat shrink....

These work great.
