Re: Alternator v. no alternator - 10% gain @ 70 km/h

Thanks for the feedback. It's always interesting to try something new and see what happens. Did you monitor battery volts to see when the electric choke is activated?

Re: Alternator v. no alternator - 10% gain @ 70 km/h

That's a good question. I know that newer computer controlled cars have tables that look at battery volts to keep the engine running right so volts can fluctuate without affecting the way it runs. ...

Re: Alternator v. no alternator - 10% gain @ 70 km/h

Oh, another idea. The Prius, Tesla and other hybrids seem to prefer using a great number of small batteries instead of a few large batteries. I don't know the benefits of that strategy, it could be...

Re: Alternator v. no alternator - 10% gain @ 70 km/h

If your lights are significantly dim, what is the battery volts at that time?
Do you think the battery is going bad?
From what I've seen, a good battery will hold a higher charge after the...

Re: Alternator v. no alternator - 10% gain @ 70 km/h

Dunno, what are the specs on the battery?
Do the batteries have model numbers on them? Or at least, what are the dimensions?
Here's a good site to correlate battery size and capacity; ...

Re: Alternator v. no alternator - 10% gain @ 70 km/h

I can't tell you with certainty how long those batteries will run your car, but I ran my car without an alternator once relying solely on a lightweight 13 pound battery. I was watching battery volts...

Oh, one more thing. The Mitsu ECU stops trying to run the car at around 9 volts. There may be a similar cutoff point on other cars. YMMV :)

On the Mitsu ECU it uses something called 'deadtime' to adjust injector pulsewidth as system volts varies. Deadtime is a set ammount of pulsewidth added to the calculated injector open time. In...

I have a downsized battery in my Laser. Originally it called for a 525CCA battery which weighed 35 pounds. I got a smaller 420CCA battery that weighs 28 pounds. Not a huge weight savings, but I...
