Does Your Car Seem Sluggish
#1
Check the alternator and regulator.
We had charging issues so the alt and reg
were replaced. Not only does the car start
easier on cold mornings but has a LOT more
pickup.
For the tech guys; How is juice from the alt
divided between charging and spark plugs?
I would not be posting this thread if there was
not a significant difference in performance with
the new reg and alt.

I should move this thread to the one already
discussing the issue, but I never graduated from
moderator school so I don't know how to do that.

It isn't. The alternator supplies the battery according to the voltage regulator and current to the rest of the car in combination from the battery. The battery acts as a stabilizer for any spikes in voltage. Once voltage has reached the ignition switch, one line runs out to the coil, where it is amplified and sent to the sparking plugs.

I have seen most original engine gauge feed harnesses fail good continuity from the 3 or 4 pin plug out to the coil, primarily due to high internal resistance within the molded connector. The crimps inside the molded connector fail a bit, and reduces your voltage at the coil itself.

If you think this is a problem, hook up a wire (temporarily) between the battery and the coil post and see if the car performs better. If it does, then suspicion is pointing towards lower voltage being delivered to the coil.

Let me check your shorts!

voltage and grounds or lack of is everything.

Everyone needs to have a digital multimeter

To recap, on cold mornings (40) it would take several seconds cranking and sometimes
tapping the gas pedal to start rough at best. With new alt/reg, tap gas, turn key two seconds =
1700 RPM steady.
