Continuity test doubt

[Ram__46]

It's a strange connector. Mercedes makes all things hard to repair diy. Engineered to go to a garage ?
Thanks again

Hi, I'm looking for an eyelet connector to put the new wire to ground. It's scarce in my city (not to be found), especially if I want a quality set. Do you think it's important to put certified connectors or it's enough using cheap chinese ones? I'm no expert about it and I'd like to avoid my car being on fire Thank you

To be honest, as long as it is solid and well crimped I would say you would be fine. Make sure you do a 'tug-test' to make sure the wire is firmly held.

Fire is not an issue in this case as the current is very low, but you don't want a bad connection giving you reliability problems.

Thank you a lot. I don't know what a tug-test is but I'll make sure is firmly crimped.

Ah, yes that's a UK term sorry!

Try and pull the wire out of the crimp. It should be virtually impossible.

We get in trouble with a Good yank , or an impulsive jerk !

(if you are building the skill with a crimp , allow for extra crimps
and spare cable and destruction test a few samples ..
( I completely distrust cheap crimp tools now )

Thank you. In fact today I tried crimping a few times with random wires just to try and the result was quite good. I only have a wire stripper that is also a crimper, so it won't be a professional result but who cares. I didn't find eyelet connectors of the perfect size but it doesn't matter. Tomorrow I'll do the repair

Let us know how it goes.

Sure, I hope the CDI (it's a diesel) ecu will come back to working order. Thanks for help

Do you think it could be a good idea to sand the free ground point (at least I suppose it's a ground point) until it's bare metal? The already occupied one seems to have little room for a new connector. Thanks again

Wouldn't do any harm yes. Cover it with a bit of grease when you've bolted the terminal up.

Lithium spray grease? Like in car batteries connectors? ?

To be honest any grease will be OK. Just to prevent any corrosion.

I just cut the ground connector's wire and the conductor is damaged. I don't know if it was the wire stripper or it was already like this. Do I have to cut in Another point or can I continue like this even with a reduced copper wire section? Thank you

I'd try and cut back a bit further if there's enough spare. Not critical though.
