Electrical solderless or soldered connectors

I will say it again: a soldered joint is the most reliable way to connect electrical components/wires together. Reliable mechanically & electrically [ least amount of resistance in the connection ]. In some cases where vibration & movement is possible, mechanical support may be needed by way of a sheath or heat shrink, but that in NO WAY detracts from the benefit of a soldered joint. Wires in an alt, starter motor, sol, rel etc are soldered...& there is a very good reason for that. It is a no brainer....
