You were measuring the voltage in the wrong place. If you had measured on the pump side of the corrosion you would have seen the lower voltage.dodgerammit wrote:Voltage and amperes are different.

I also did it on my Dodge I had.
Why put fancy, spendy lights in, when for about $40 in parts, you can make the factory setup much brighter?
In both cases I ran a stock style sealed beam. No silverstars, no H4s, etc. The lights on both my truck and the Jeep are very impressive. They are brighter than most newer cars with composites. And definitely brighter when those composites have a few years of age to them.
No light is going to show its full potential without proper amperage going to it.
Last time I measured, I was losing .4V between the alternator and the headlight plug, while the lights were on, so I am good on power.
I measured at the terminals on the headlight connector. That is why I said power, not voltage. P = VI.REDONE wrote:Yep, it's true CSU Engineer, it's called Ohm's Law, and it works like this.

If this thread survived the previous nonsense just to get resurrected now, I might as well get ahead of this one. Better to go off in the weeds than down the toilet!
Dude, no. Just no. You have a garden hose with the water on and on /off nozzle. The water is voltage. Turn the nozzle on. That is electron flow and amps. Just don't tell anyone which way the electrons actually flow.REDONE wrote:Yep, it's true CSU Engineer, it's called Ohm's Law, and it works like this.

Measured at pump. In fact, pump was plugged in and I was probing the terminals. Voltage WAS there. Just above 12 iirc. Again, the wiring was just badly corroded. Know what color copper turns when it corrodes? Yeah, the wiring was that color. I even cut it in half in the middle. Corrosion wasn't as bad, but it was still there. Basically, the wire size had been reduced over time, building resistance.SJTD wrote:You were measuring the voltage in the wrong place.

Say you have badly corroded battery posts on a fully charged battery. If you measure the voltage while cranking on the post itself you'll see the full battery voltage. Move to the clamp which is past the corrosion and you'll see what the starter sees. (Yeah, yeah, what the starter sees plus the drop across the cable)

Thanks.csuengr wrote:Hellas.
Some of Hella's E-code H4's have a large seperation between the high beam and low beam. Depending on which model and the hieght of truck you can probably strike a balance that suits you. In a car that sits lower its more dificult to do with those models.csuengr wrote:...Had to re-aim them as on high they were pointing into the trees. Not much else to say at the moment.
