Can someone tell me if my volts are fluctuating with the rpms when the car is surging because of an injector with bad resistence?

Would the volts fluctuate with the rpms if the resistance were good and the injector(s) were clogged?

If the resistance were bad would I need a new injector?

 

Have your car get a free electrical check at Checkers or wherever, that will rule out your battery being half-dead and it will also check the charging system. My car did that and it was due to the regulator being on the fritz. Still didn't change it out... only a beater anyway.

 

It is normal for the volts to fluctuate with rpm. When the engine isn't at higher rpm the altenator isn't turning as fast reducing the amount of voltage. When you increase rpm, in turn increaseing speed of altenator, it produces more voltage. This is seen often on a car with underdrive pulleys. I hope this is what you were talking about, at least thats what I got out of the question.

 

yeah i guess thats what I'm talking about. It was a terrible description.

That makes sense.

 

Unhook the small wires going to your alternator and then start the car. Does it still surge?

 

Whoa! Don't unhook the wire going from the AC generator. That could cause many problems that I am sure you don't want to deal with. When cars had DC generators, you could just unplug them or unplug the battery while the car was off, no harm no foul. But now that we use AC generators, it is not recommended to unplug either the battery or the generator.

 

Yeah okay why is that?
Now I suppose when your alternator dies you just have to get a whole new car because "that could cause many problems".


Let the man troubleshoot his problem already. If someone is that scared to touch something on their car then they'd go to a mechanic and probably not ask for tips here.

FYI the car will start and run just fine without an alternator. It just won't be charging the battery while it's running but that's okay as long as it's temporary.
