I solder instead of crimp just because I don't have any other reason to buy a crimper. I buy the ends that fit the tightest and sometimes I need to,drill,them out a tiny bit to get the best fit. I use the fluxed solder lugs and I add a little extra No Korrode flux and a few more bits of wire solder to make sure they solder fully. Then finish them with self sealing heat shrink.
The negs. already go to the block but I also run both pos. cables to the starter for less voltage drop to it. There's plenty of room on the starter lug and plenty of room to installi it.
True one can solder , but i always fear of the solder wicking up the wire , making it stiff . But this is just a matter of Technique + skill + to me solder is a higher resistance connection .
To each his own. I think once you get the solder thing down , its def a viable connection.
I greatly like crimping better , with glued shrink tubing , and TINNED copper lugs .
But then there is the crimper and the dies. Dies are expensive . BUT being an electrician a crimper set up is not an issue for me.
The hammer , die crimper is useless .
BUT there is a CHEAP 39$ ( yes ) yellow china 3 ton hyd crimper on Ebay that can and will work for several sets of cables. Comes with metric dies , just take an educated guess on which is correct and make a test crimp.
I have made my own cables and military battery terms for 2 trucks AND pre fabbed a set for my son in Colorado , and sent the china crimper .
So all in all , 3 sets which i believe is a life time achievement . No more please . lol
Materials are expensive ( also ebay ) and will cost 180-230$ depending how far you go .
