SOURCE: 24 volt charging problems .2

A 12 volt battery is actually 13.2 volts fully charged. If you are reading 16 volts, you are probably getting extranious voltage from the system somewhere, especially if the vehicle is running when you check the voltage. The alternator will put out about 15-18 volts to charge the battery normally, and yours may put out 28-32 volts to charge them in series, but the batteries, when disconnected, should never read more than about 13.2 volts each. Typically, it will read about 12 1/2 volts when disconnected. COMPLETELY DISCONNECT BOTH OF THE BATTERIES. If you still read 16 volts when it is disconnected, you must have a bad meter because the battery can't produce that much voltage, no matter what. (Six 2.2 volt cells connected in series inside the case.) Put the meter on a known good battery on another car that is not running and see if you get the same reading. It sounds like the other battery is almost dead, regardless, and it sounds like your series/parallel switch may be malfunctioning. (That is the switch that puts the battery in series to run the 24 volt starter, then puts the batteries in parallel to run the remainder of the vehicle on 12 volts. This is all assuming that you have a diesel vehicle with a 24 volt starter and that is why you have two batteries.

SOURCE: how do I get 12 volts at the factory installed trailer connector

You are correct. There is a fuse in the underhood fuse/relay compartment that powers up the pin. It is one of the larger fuses and should be labeled as "AUX". Also check that the power wire is connected to the AUX bolt terminal. They shipped from the factory disconnected and the cable was zip-tied to something below the fuse box.

Po141 code on my 2003 Chevy s 10 and I changed my down stream sensor and reset the code about 500 miles later it came back on I reset it again and 200 miles later it is back on again what do I do now

unplug the O2 sensor. Turn the key to the run position. Check for 12 volts at the pink wire.

If there is no power check the fuse (O2 HTR). If the fuse is good you will need to find the open in the pink wire.

If there is power hook your test light to the power side of the batter (Positive lead of voltmeter to positive side of the battery. check the brown wire with the engine running. You should see 12 volts or the test light should illuminate. (the computer supplies the ground for the heater circuit).

If there is no power or illumination check the brown wire for continuity between the sensor and the computer. If there is power than either the new sensor is bad, the wrong sensor was replaced, or there is corrosion in the power side of the wiring which is a little more difficult to figure out.

Ok here goes, I'm not mechanically minded so please bear with me. I think I may have broke the connection cords that connect to the battery terminals while trying to put in a new battery as that's what I...

Use a volt meter or 12 volt test light to test for current at different places. Start with the battery terminals, then leave the one test lead on the negative terminal and test for volts further away from the battery,(on positive side of circuit) like the big bolt connection i see in the pic. then test in the fuse box for volts. This will tell you where the bad connection is..

30amp auto shutdown fuse blows is it alternater

The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements. The Fuel Pump Relay is a separate relay controlled by the ASD relay input to the PCM. Fuse #12 (10amp) provides 12 volts to the coil side of both the relays and the ignition switch. Fuse #6 (30 amps) supplies 12 volts to the output side of the relay. Fuse #16 (15 amp) from the relay output to the Oxygen Sensors and Fuse #26 (15 amp) relay output to the PCM. Fuse #24 (20 amp) is Fuel pump relay output to fuel pump. Fuse #19 (10 amp) supplies 12 volts direct to the PCM.
look for burned or melted wires in the offending circuit.
sounds like you wiggled a wire while installing new relay.

Brake lamps does not working nissan 1996

You may have a defective switch, to check remove any panel found under the dash that blocks access to the brake pedal arm, then look up above the pedal, you will see the brake light switch, with a 12 volt test light probe (about $4 at most parts stores) check the connector to the switch, it should have 12 volts at one side of the connector and 12 volts at both sides when the brake pedal is pressed. Replace switch or repair connector as needed.

I am not getting a signal to my fuel pump, fuel pump relay nor the 10 amp fuel pump relay fuse. I have checked my wiring from the ECM to the FPR and it is good. Where does the power come from through the...

The fuel pump relay is powered by a fusible link connected to the starter solenoid on the positive battery terminal. That fusible link feeds the 10 amp fuse near the relay. You can test the fusible links with a 12 volt test lamp. If the fusible link test okay check for an open circuit in the wire between the link and the 10 amp fuse. Hope this gets you fixed.

How to find positive power 12 volts and ingnition switch 12 volts

Should have said that in the first place. Use a test light and locate the wire that is hot on the ignition switch with the key off. (to avoid constant draw, turn the key to the "on position after locating the one that is hot all the time, then find the thickest hot wire on the other side of the switch that is hot in the "on" position. The switch itself is located on top of the steering column under the dash and generally is easier to reach if you remove the plastic covers and the bolts that hold the column on the dash. You can use any of those bolts to attach your ground wire.

My car phone charger broke off in the cigerette lighter n so the fuse has gone. How do i find out which fuse it is without having a manual?

But a $5, 12 volt DC test light & put clamp to ground & touch each side of tips of fuses with pointed end. If it lights up on one side, and not the other, it's blown. A multimeter will do it too. Ground meter, touch each tip & look for 12 volts or more on each side.

If you have a 12 volt test lamp, try this: Turn on the rear defroster. Attach the clamp to a good ground point; the door latch hoop is good)...Now, touch the test lamp to the extreme left and extreme right sides of the grids, on the inside of the glass. If the light does not light in either place, you probably either have a bad defroster relay, or the wires coming to the rear grids is off. Please feel free to get back to me with the results of your test.
