    Charging Problem

    Just finished installing the new alternator from rockauto.com, ign light came up as normal and the off. But I was getting low voltage, 12.40 at idle, and 12.16 revving. Then, ign light came back one. Decided to do a test running a wire from fuse box to alternator to check. No I'm getting 13.76 at idle. Problem is that I'm over 17.09 when revving. I'm guessing I have a bad wire in the wire harness and I need a new voltage regulator. Any suggestions?

    Autozone kept selling me the wrong one(system says external regulated but they are internally regulated). They took it back and gave me my money. Ordered one from rockauto.com I'll keep you guys posted.

    I read your post, for the dragon 521, that's why I made the fuse box, followed your instructions. Same way to removed the amp meter, you explained how to install it, I just went backwards and removed mine(previous owner made a mess with the wires) I just bought a Pathfinder alternator to match your post and fix this charging mess in my 521 I'll do the test light to the "L" terminal tomorrow morning. Thanks

    Both VR smoked out. This alternator is extremely weird, makes a ticking sound when truck is off. Also, there's a ticking sound behind the dash, near the key (like a solenoid sound) So, bypass everything, just connect the pos and the neg? Don't worry about the t plug?

    Been stranded at night (not once, but twice) in a high traffic area in Orlando, FL with my 11 year daughter and no battery, so no emergency lights, deadly and scary... People don't care... But what can I do I learned to carry 2 extra batteries with me

    Ground, checked! Both, the ground from block and ground from VR are there, made new wires and clean bolts.

    Honestly, I ordered an external regulated alternator, that's the one pictured. I did the installation and light turned off, a week later, truck died, dead battery

    Even if I go with a internal regulated newer alternator, how would I know I'm not getting a junk?

    Yes, they were wrong. I followed my wires instead of VR wires, now my light is on (constantly) at least now the truck is telling me is not charging 😉

    I meant the testing light is brighter. I'm getting over 16 volts at white/black stripe
