Ballast resistor


Recommended Posts

I've done it,

I also replaced it as soon as I could (= as soon as I got home).

 

My understanding has always been,

the pump is designed to run at 12-13v.

When you're starting off battery power, you're in the right range,

once the engine fires, and the alternator starts producing, you need the ballast resistor to bring the voltage back into range.

Well said, and exactly right. Unless you enjoy replacing fuel pumps prematurely, keep it in the circuit, and keep the contacts clean. jamminz.gif
