1 wire internal or external oem alternator

But anyway, I forget some have fallen in love with electronically controlled cars and accessories. I am going backwards because it’s too complex in many ways, especially a road side repair
Your not going backwards...

The parts you don't add don't cause you no trouble!

Modern cars are VERY reliable in spite of their electronics, now let's check back in 50 years and see if you can take a 2024 car with 320,000 miles, that sat in a garage for 4 years without being started and and was only started occasionally for 15 years prior and have it start and keep running.
