with my truck being a pretty basic model 2004, im guessing i dont have the bigger alternator for the AGM requirements. its a pia to actually view the label on stock alternator. not sure how to test it.
lol...might get a regular battery for $80 MaxxStart walmart and call it a day at this point.
reminds me of 'easy' tasks at work. careful what you wish for. hybrid bumper/winch = way more than that. light, wiring kit for light, battery, diodes, alternators, battery fitment, and im sure a few other surprised along the way |
You can just look up a 1N4004 diode, they typically come in a ribbon of 5 or more. Cathode goes towards the firewall, it's the side of the diode with the stripe on it. I DID NOT solder, I folded the leads over and inserted them directly into the fuse buss with a small screwdriver. If there's an issue, the diode will pop like a fuse.
Lead acid batteries can handle up to 14.8v, so this mod won't hurt the vehicle with the existing battery.
The only issue with the alternator is in the AMPS it's capable of producing versus the load you plan to run, and you aren't running anything big so no issue. The voltage regulator comes preset for some reason to 13.2v. hence the diode. In older cars, it was totally normal to have an alternator pumping 14.4-14.8 all day long. AGM likes at least 13.6 to be happy.
