help me Plz I'm abt to put a bullet in this thing
So I have an 00 durango I did this setup today the only thing that was different was the back of the alternator I have a clip on mine so o did it the way you said now my volts are going to 14.7 ish when it's turned on the lights are pulsing and it just seems to generally be overcharging ant ideas? Do I need a different regulator?

Yes!! This worked for me, and saved me from buying the $20 yellow resistor. It really pays to read and consider every post. Thanks Madore33

Voltage gauge
I installed this bypass on my 2001 ram 1500 with the 5.9 gas engine. The bypass worked and is charging the battery and I’m getting 14.5 volts. The only issues I’m having is the voltage gauge pegs out sometimes at 18 volts but the battery is still at a normal 14-14.5 volts. The gauge doesn’t max out all the time. Sometimes it pegs out and then after a few minutes it will return to the normal reading. Sometimes it will peg out and stay pegged out for the entire ride. Has anyone had this issue or know of anyway to fix it?

2001 5.9 2500 4x4. Same problem. When it first happened I got a "check gauges" alarm, the voltmeter was pinned. When the PCM detects a high voltage condition it sets the alarm and pins the voltmeter. I assumed it was legitimate and installed an external regulator. Same problem. This time I checked the voltage with the external regulator. Normal. So, I'm assuming that there is something wrong with the voltage sensing circuit in the PCM. It's a PITA having the alarm go off periodically, but there is nothing wrong with the voltage, so I just drive it. It seems to be worse in hot weather, but not consistently.

Diy conversion
Hi so my son did the conversion on my 89 ram 250 5.2 liter van.started and tested good. Drove 50 miles to work with check engine light on. Drive home with check engine light off.checked battery it has a low voltage checked regulator and its not working. Any thoughts... Thanks
