I never had success with the ELD bypass on my car. My case the resistor probably wasn't enough to trick the ELD into a higher output. For those who may wonder. The bypass is very safe and will not put any more strain on a alt. It would last just as long as without this feature. As far as fuel economy. You may or may not see much of a difference. Even with the HO alt I have there wasn't any notable drop in MPG. One thing people don't tend to do and don't realize is that IF your battery is weak the voltage out of the alt will sag over say a strong battery. A alt is essentially a trickle charger/power supply. When the vehicle is running the alt is supplying the power. The battery at this point is storage/backup and the alt will maintain charge of the battery. Also whenever you get a new battery, if you can, always use a external charger to charge the battery fully. In many cases the battery is roughly 80% charged to increase shelf life.Honda-ELD
Here it's an ELD Electrical Load Detector that was screwing me, and a way to get around it and still pass emissions (bypass with resistor).
This car I purchased for $1400, I would simply never pay $450+ for this electrical system that now doesn't drop below 13.4V at retarded deafening volumes (although they are GREAT QUALITY alternators). Just picked up a rebuilt alternator I found at a junkyard for $30 lol 3 month free warranty, and keeping my fully functional one as a backup. I'm well aware 99% of companies rebuild them to only last a year so you have to keep paying them. Stinger I've heard great things about, same with Mechman, Ohio Gen, Iraggi. Probably some of the only reputable alternator companies left that don't advertise their 220A output at 6k RPM's like the crooks do.
My alternator swap for me took only 30 minutes, I actually saw this genius DIY write-up who took his axle off when all I did was take a fuel line and power steering hose off, two bolts then pulled it out the top lol. Dropped it back in and done, it's taken me longer to change my oil before(darn Jiffy lube purposely over-tightening it, make me stick a screw driver through it)... Not against these companies, and I realize it costs money for REAL quality. But I'm 24 and poor, and happy to take 30 minutes to swap alternators when needed (probably about a half year from now). Again I'm not trying to say HO alternators from Stinger and other reputable companies aren't worth every penny. They custom build these things and that costs not only money but time, and I give respect when it is due, they are great units.
Perhaps five years from now when I can afford a car that's not a beater, I will invest in the Stinger HO. But I want to have the sound system to suck the juice, mine is only 2,360 watts RMS pretty whimpy.
I can understand not wanting to toss more money into a beater but on experience with my brothers truck (went through 4 remanufatured alts of varying issues) and with talking to Mike himself and actually seeing/feeling what crap goes into remanufatured alts. I can honestly say the price is worth it. In many cases your getting something that will most definitely last a lifetime. You may be supprised how little a rebuilt alt can be. Just to give you a idea. My stock alt rebuilt is under 200.
