Can a voltage regulator be put in a jeep?
I’ve seen few videos on the regulators but none put in to a Jeep, so here it is. On these Jeeps and a few other vehicles the voltage regulator has been moved from the alternator to the computer. Not a bad thing as long as it doesn’t stop working. As far as I know this is the only way to bypass the problem incase the internal regulator fails.
Where can I find a voltage regulator for my car?
There are 14 references cited in this article, which can be found at the bottom of the page. Voltage regulators are commonly found in vehicles and other electronic equipment. A voltage regulator will limit the maximum amount of voltage from a power source and prevents a device or alternator from shorting and overheating.
What are the signs of a bad voltage regulator?
Signs of a bad voltage regulator in a vehicle include dimming or pulsing lights or a dead battery. If you have electrical equipment that won’t turn on, that could also indicate a bad voltage regulator—the regulator could either be letting no power through or letting through too much and damaging the other components.
What should the voltage be on a battery regulator?
The regulator should cap the output of your battery at around 14.5. If the voltage reads over 14.5, it probably means that you have a faulty regulator. If your voltage reading is below 13.8 volts, you have a weak battery and will need to replace it soon. Read the schematics that came with the voltage regulator.
Where is the voltage regulator located on a jeep?
Great for Late Engine to early vehicle swap. Since 1987 for Dodge and Chrysler and 1991 for Jeep, vehicles have external regulator alternators that are controlled by the Alternator Voltage Control Module inside the Engine Control Unit, ECU (computer) . This is often called the ECC, ECM, EEC, or PCM.
Can you use an external voltage regulator on a 1987 Dodge alternator?
This kit can be used on Standard and High Output Alternators with External Voltage control. Also, this product can be used as a wiring harness and external voltage regulator replacement kit for any 1987 and earlier Chrysler Family vehicle alternator with dual insulated brushes.
Why is the alternator on my Jeep not charging?
Looks like the field coil of the alternator isn’t getting power. There are 3 wires attached to the alternator. One is a big fat wire that goes to the battery, this is the alternator output. The other two wires feed power to the field coil.
Where are the fuses on a jeep alternator?
If you don’t see voltage on the field coil terminals, you might have a blown fuse. The field coil is powered by a box called Powertrain Control Module, and there are 3 fuses that might be of interest, numbered 6, 19, and 26 according to the schematic (see below).
Where to test the PCM on a Jeep Wrangler?
3-Test for reference voltage (5v) coming out of the PCM at pin 17 ( orange wire) at the black connector and pin 31 (violet/orange wire) at the white connector. If the power input leads and grounds are good, but nothing is coming out of the two reference leads, then the PCM is smoked. Period.
Is the O2 sensor on a Jeep Wrangler NTK?
Hopefully the O2 sensors are NTK and not Bosch which is known to cause problems in our Jeeps. I’m having some problem as fireman posted earlier in the thread. Don’t have power to pin 2 orange wire. Have power to all fuses in fuse block.
What is 5V output on Jeep Wrangler?
The 5v output is power for these: TPS, MAP, speed, crank & cam sensors. A sure sign you have lost that output is when you turn the key to the on position & the gauges do not move. You also lose communication with the OBDII data port & a scanner will not “communicate” & not read.

Which is the fuse on a Jeep Wrangler?
As to which fuse, I don’t know but if there is no power from that wire I would check the fuses. I think in the earlier XJs that was fuse 11 in the junction block & in the ’04 TJs it is fuse 12 in the fuse block. If the fuse is good see if you are getting 12v power to the fuse which comes from the ignition switch.
Why is my alternator not working with an external voltage regulator?
Often, especially after installing a high output alternator with external voltage regulator, the alternator voltage control module in the ECU will fail , leaving you with a dead charging system where your external regulator alternator doesn’t work , or doesn’t work the way it should , yet your engine runs fine.
What kind of voltage regulator for Denso alternator?
Modified Driver for Denso Alternators that have the plug coming out of the side of the alternator Used in conjunction with External Voltage Regulator kits ERCKFRM, ERCK AND ERCKE kits Repair Connector for Denso and Mitsubishi units.
