Voltage regulator and ballast resistor

[Shut]

Hello to all

I see that the Voltage regulator and ballast resistor dont work fine and I need to replace

What is the right that I need to buy? No references or numbers in the parts

Thanks to all

The car looks freshly painted. Do you have a good ground ? You need good metal to metal contact. The paints should be scraped off where the regulator is bolted to the firewall. only enough to get a good ground.

Thank you moparleo

I will do the better ground in the firewall, but the ballast resistor its broke...

What makes you think it's broken?

The ceramic of the spring is broken. And when vibration is high the terminals move and stop the engine
