I recently did the big 3 and have a couple questions.
First, I had a hard time crimping my 1/0 Ring terminals. I thought I did a good job and then the wire slipped out - so obviously I didn't. Then I did it again and added some solder to the connection, but this also did not work for me. Reason being - after it cooled and looked all great and super secure, I could just flick off the solder! It wasn't sticking to the ring terminal!
I tried some different solder and the new kind worked a little better - but still I am not too confident.
So, question: What is the best kind of solder to use in this situation?
(I've seen a lot of different mixes and have no idea what to use)
Second question, how to do I test my grounds with a multimeter?
And please, sorry for being totally clueless, but I am - so please explain this to me like I know nothing.
I went to home depot and bought one for $36. It's the Sperry DM-4100A - and I have no idea how to use it. For one, is this one good enough for using with my car battery and all? Don't want to "blow" it or something like that.
And I've read some people talk about connecting a part to your battery and another part to your ground location for your amps, but it's still a little vague to me exactly what to do here. What do I set my multimeter to? And what part of the battery to I connect one end to (+ or -). And do I need to disconnect the positive side of the battery before doing this? (sounds like so from others but not sure if that's what they meant).
Thanks for clarifying this all for me!
